data and to provide linear, non-retimed data from d igitally modulated SDH/
SONET STM-64/OC-192 optic al si gn als , a s well as signals em ploying forward
error correction (FEC) at 10.664 Gb/s (option 106). The receiver is based on
an amplified PIN re c e iv er to produce a linea r ou tput with AGC stabiliz a tion.
The receiver is designed to provide –16 dBm sensitivity with PRBS lengths to
31
–1 with BER performance of at least 1E-10.
2
The recovered clock can be used as a trigger input for the Ag il en t Infi ni iu m
DCA to allow optical eye diagram measurements when no external clock signal is available for triggering. The recovered clock also provides the required
clock input for the error detector of the Agilent 71612B error performance
analyzer. The non-retimed data output can be used with an er ror detector to
measure and optimize BER. The output of th e re c eiver is also appropriate for
eye contour and Q-factor measu re m ents.
The Agilent 83434A can be combined with the Agilent 83433A 10 Gb/s lightwave transmitter to create a complete optical link for system or fiber testing,

Fiber-Optic Connectors
Today, advances in measurement capabilities make connectors and connection techniques more impor tant than ever. Damage to the connectors on calibration and verification devices, test ports, cables , and ot her device s can
degrade measurement accuracy and damage instruments. Replacing a damaged connector can cost thousands of dollars, not to mention lost time! This
expense can be avoided by observing the simple precautions presented in this
book. This book also contains a brief list of tips for caring for electrical connectors.
Choosing the Right Connector
A critical but often overlooke d fa c t or in making a good lightwave meas urement is the selection of the fiber-optic connector. The differences in connector types are mainly in the mechanic a l assembly that holds the ferrule in
position against another identical ferrule. Connectors also vary in the polish,
curve, and concentricity of the core within the cladd ing. Ma tin g one st yl e of
cable to another requires an adapter. Agilent Technologies offers adapters for
most instruments to allow testin g w ith many differen t c a bl es. Figure3-1 on
page 3-9 shows the b a sic components of a typical c onne c tors.
The system tole ranc e for reflection and in se rtion loss must be kno wn w h e n
selecting a connector from the wide variety of currently available connectors.
Some items to consider when selecting a connector are:
• How much insertion loss can be allowed?
• Will the connector need to make multiple connections? Some connectors are
better than others, and some are very poor for making repeated connections.
• What is the reflect ion tolerance? Can the syst em take reflection degrada tion?
• Is an instrument-grade connector with a precision core alignment required?
• Is repeatability tolerance for reflection and loss important? Do your specifica-

tions take repeatability uncertainty into account?
• Will a connector degrade the return loss too much, or will a fusion splice be required? For example, many DFB lasers cannot operate with reflections from
connectors. Often as much as 90 dB isolation is needed.
Figure 3-1. Basic components of a connector.
Over the last few ye a rs, the FC/PC style c o nne c tor has emerged as th e most
popular connector for fiber-optic applications. While not the highest performing connector, it represents a good compromise between performance, reliability, and cost. If properly maintained and cleaned, this connector can
withstand many repeated connections.
However, many instrument specifications require tighter tolerances than most
connectors, inc lu ding the FC/PC style, can delive r. These instruments cannot
tolerate connectors with the large non-co nce ntr ici ti e s of the fiber common
with ceramic style ferrules. When tighter alignme nt is required, Agilent
Technologies instru ments typical ly use a connector such as the Diamond
HMS-10, which has concentric tolerances within a few tenths of a micron. Agilent Technologies then use s a spec ial universal adapter, which allows other
cable types to mate with this precision connector. See Figure 3-2.

Figure 3-2. Universal adapters to Diamond HMS-10.
The HMS-10 enca se s the fiber within a soft nic kel silver (Cu/Ni/Z n) center
which is surrounded by a tough tun gs ten carbide casing, as shown in
Figure 3-3.
Figure 3-3. Cross-section of the Diamond HMS-10 connector.
The nickel silver allows an active centering process that permits the glass fiber
to be moved to the desired position. This process first stakes the soft nickel
silver to fix the fiber in a near-cen ter location, then uses a post-a c tive staking
to shift the fiber into the desired position within 0.2 µm. This process, plus t he
keyed axis, allows very precise core-to-core alignments. This connector is
found on most Agilent Technologies lightwave instruments.

Fiber-Optic Connectors
The soft core, wh ile allowing precise cent ering, is also the chief lia bility of the
connector. The soft material is easily damaged. Care must be taken to minimize excessive scra tching and wear . Wh ile minor wear is not a problem if the
glass face is not af fected, scratches o r grit can cause the glas s fiber to move
out of alig nment. Also , if unke yed c onnect ors a re us ed, th e ni ckel silver can be
pushed onto the glass surface. Scratches, fiber movement, or glass contamination will caus e loss of s igna l and in creas ed re fl ect ion s, res u ltin g in p oor retu rn
loss.
Inspecting Connectors
Because fiber-optic connectors are susceptible to damage that is not immediately obvious to the naked eye, poor measurements result without the user
being aware. Microscopic examination and return loss measurem en ts are the
best way to ensure good measurements. Good cleaning practices can help
ensure that optim u m c onnector performa nce is maintained. With glass-toglass interfac e s, any degradatio n of a ferr ule or the end of the fibe r, any stray
particles, or finger oil can have a significant effect on connector performance.
Where many repeat connections are required, use of a connector saver or
patch cable is recomme nd ed.
Figure 3-4 shows the end of a cle an fiber-opt ic cable. The dark circle in th e
center of the micrograph is the fiber’s 125
the light. The surrounding area is the soft nickel-silver ferrule. Figure 3-5
shows a dirty fiber end from neglect or perhaps improper cleaning. Material is
smeared and gr ou nd i n to t he end o f t he f ib er ca usi ng li ght sc att eri ng an d poo r
reflection. Not only is the precision polish lost, but this action can grind off the
glass face and destroy the connector.
Figure 3-6 shows physical damage to the glass fibe r end caused by either
repeated connections made without removing loose particles or using
improper cleaning tools. When severe, the damage of one connector end can
be transferred to anothe r good connector endface that comes in co ntact with
the damaged one. Periodic checks of fiber ends, and replacing connecting
cables after many connections is a wise practice.
The cure for these problems is disciplined connector care as described in the
following lis t an d in “Cleaning Connectors” on page 3-15.

Use the following guidelines to achieve the best poss ible performance when
making measurements on a fiber-optic system:
• Never use metal or sharp objects to clean a connector and never scrape the
connector.
• Avoid matchi ng gel and oils.
Figure 3-4. Clean, problem-free fiber end and ferr ul e.
Figure 3-5. Dirty fiber end and ferrule from poor cleaning.

Reference
Fiber-Optic Connectors
Figure 3-6. Damage from improper cleaning.
While these often work well on first insertion, they are great dirt magnets. The
oil or gel grabs and holds grit that is then ground into the end of the fiber.
Also, some early gels were designed for use with the FC, non-contacting connectors, using small glass spheres. When used with contacting connectors,
these glass balls can scratch and pit the fiber. If an index matching gel or oil
must be used, apply it to a freshly cleaned connector, make the measurement,
and then immediately clean it off. Never use a gel for longer-term connections
and never use it to improve a damaged connector. The gel can mask the extent
of damage and continued use of a damaged fib er can trans fer damage to the
instrument.
• When insertin g a fiber-optic cable into a connector, gently insert it in as
straight a line as possible. Tipping and inserting at an angle can scrape material
off the inside of the connector or even break the inside sleeve of connectors
made with ceramic material.
• When inserting a fiber-optic connector into a connector, make sure that the fiber end does not touch the ou ts ide of the mating connector or adapte r.
• Avoid over tightening connections.
Unlike common electrical connections, tighter is not better. The purpos e of
the connector is to bring two fiber ends together. Once they touch, tightening
only causes a greate r f or c e to be a pp lied to the delicate fibers . With connectors that have a convex fiber end, the end can be pushed off-axis resulting in
misalignmen t a nd excessive return loss. Many measure ments are actuall y
improved by backing off the co nnector pressu re . Also, if a piece of grit does
happen to get by the cleaning procedure, the tighter connection is more likely
to damage the glass. Tighten the connectors just until the two fibers touch.
3-13
Reference
Fiber-Optic Co nnectors
• Keep connectors covered when not in use.
• Use fusion splices on the more permanent critical nodes. Choose the best con-
nector possible. Replace connecting cables regularly. Frequently measure the
return loss of the connector to check for degradation, and clean every connector, every time.
All connectors should be treated like the high-quality lens of a good camera.
The weak link in instrument and syste m reliability is often the inappropriate
use and care of the connector. Because current connectors are so easy to use,
there tends to be reduced vigilance in connector care and cleaning. It takes
only one missed cle a ning for a piece of grit to perm a nently damage the gl a ss
and ruin the conne c to r.
Measuring insertion loss and return loss
Consistent measureme nts with your lightwave equipment are a good indication that you have good connections. Since return loss and in s ertion loss are
key factors in determining optical connector performance they can be used to
determine connector degradation. A smooth, polished fiber end should produce a good return-loss measurement. The quality of the pol ish establishes
the difference bet w een the “PC” (physical contact) and the “Super P C ” connectors. Most connectors today are physical contact which make glass-to-glass
connections, therefore it is critical that the area around the glass core be clean
and free of scratches. Although the major area of a connector, excluding the
glass, may show sc ratc hes and wear, if the glass has maintai n e d its polished
smoothness, the connector can stil l provide a good low level return loss connection.
If you test your cables and accessories for insertion loss and re turn loss upon
receipt, and retain the measured data for comparison, you will be able to tell in
the future if any degradation has occurred. Ty pical values are less than 0.5 dB
of loss, and somet im es as little as 0.1 dB of lo ss wi th high performance co nnectors. Return loss is a measure of reflection: the less reflection the better
(the larger the return loss, the smaller the reflection). The best physically
contacting connectors have return losses bette r than 50 dB, althoug h 30 to
40 dB is more common.

Visual inspection of fiber ends
Visual ins pe cti on of fi ber en ds c an be hel pfu l. Cont amin at ion o r im perf ect ion s
on the cable end fa ce c a n be detected as well as cr a c k s or chips in the fiber
itself. Use a microscope (100X to 200X magni fi cation) to inspect the entire
end face for contam ina tion, raised meta l, or dents in the metal a s well as any
other imperfections. Inspect the fiber for cr a c k s a nd ch ip s. Visible imperfec tions not touching the fibe r core may not affect performance (unl es s the
imperfections keep the fibers from contacting).
WARNI NG Always remove both ends of fiber-optic cables from any instrument,
system, or device before visually inspecting the fiber ends. Disable all
optical sources before disconnecting fiber-optic cables. Failure to do
so may result in permanent injury to your eyes.
Cleaning Connectors
The procedures in this section provide the proper steps for cleaning fiberoptic cables and Agilent Technologies universal adapters. The initial cleaning,
using the alcohol as a solvent, gently removes any grit and oil. If a caked-on
layer of material is still present, (this can happen if the beryllium-copper sides
of the ferrule retainer get scraped and deposited on the end of the fiber during
insertion of the cable), a second cleaning should be performed. It is not
uncommon for a cable or connector to req uire more than one cleaning.
CAUTION Agilent Technologies strongly recommends that index matching compounds
not be applied to their instruments and accessories. Some compounds, such as
gels, may be difficult to remove and can contain damaging particulates. If you
think the use of such compounds is necessary, refer to the compound
manufacturer for infor mation on application and cleani ng procedures.

To clean a non-lensed connector
CAUTION Do not use any t ype of foam swab to clean optical fiber ends. Foam swabs can
leave filmy deposits on fiber e nds that can degrade performance.
1 Apply pure isopropyl alcohol to a clean lint-free cotton swab or lens paper.
Cotton swabs can be used as long as no cotton fibers remain on the fiber end
after cleaning.
2 Clean the ferrules and other parts of the connector while avoi ding the end of
the fiber.
3 Apply isopropyl alcohol to a new clean lint-free cotton swab or lens paper.
4 Clean the fiber end with the swab or lens paper.
Do not scrub during this initial cleaning because grit ca n be caught in the
swab and become a gouging element.
5 Immediately dry the fiber end with a clean, dry, lint-free cotton swab or lens
paper.
6 Blow across the connector end face from a distance of 6 to 8 inches using
filtered, dry, compressed air. Aim the compressed air at a shallow angle to the
fiber end face.
Nitrogen gas or com pressed dust remo ver can also be used.
3-16
Reference
Fiber-Optic Connectors
CAUTION Do not shake, tip, or invert compressed air canisters, because this releases
particles in the can into the air. Refer to instructions provided on the
compressed air canister.
7 As soon as the connec tor is dry, connect or cover it fo r later use.
If the performance, after the initial cleaning, seems poor try cleaning the connector again. Often a second cleaning will restore proper performance. The
second cleaning should be more arduous with a scrubbing action.
To clean an adapter
The fiber-optic input and output connectors on many Agilent Technologies
instruments employ a universal adapter such as those shown in the following
picture. These adapters allow you to connect the instrument to different types
of fiber-optic cables.
Figure 3-7. Universal adapters.
1 Apply isopropyl alcohol to a clean foam swab.
Cotton swabs can be used as long as no cotton fibers remain after cleaning. The
foam swabs listed in this section’s introducti on are small enough to fit into
adapters.
Although foam swabs can lea ve filmy depo sits, these d eposits are very thin, an d
the risk of other conta m ination buildup on the inside of adapters greatly outweighs the risk of contamination by foam swabs.
2 Clean the adapter with the foam swab.
3 Dry the inside of th e ad a pter with a clean, dry, foam swab.
4 Blow through the adapter using filtered, dry, compressed air.
Nitrogen gas or compressed dust remover can also be used. Do not shake, tip,
or invert compressed air canisters, because this releases particles in the can
into the air. Refer to instructions provided on the compressed air canister.
