Notes:
1. Installation temperature is the range over which the cable can be bent and pulled without damage. Below -20°C the cable becomes brittle and
should not be subjected to mechanical stress.
2. Short Term Tensile Force is for less than 30 minutes.
3. Short Term Bend Radius is for less than 1 hour nonoperating.
4. 90° bend on 25 mm radius mandrel. Bend radius is the radius of the mandrel around which the cable is bent.
5. Typical data are at 25°C.
6. Propagation delay constant is the reciprocal of the group velocity for propagation delay of optical power. Group velocity is v=c/n where c is the
velocity of light in free space (3xl08 m/s) and n is the eective core index of refraction.
7. Note that aR rises at the rate of about 0.0067 dB/°C, where the thermal rise refers to the LED temperature changes above 25°C. Please refer to

Plastic Fiber Connector Styles
Connector Description
Four connector styles are avail able for termination of
plastic optical ber: simplex, simplex latching, duplex
and duplex latching. All connectors provide a snap-in
action when mated to Versatile Link components.
Simplex connec tors are color coded to facilitate identication of trans mit ter and receiver connections. Duplex
connectors are keyed so that proper orientation is
ensured during insertion. If the POF cable/connector will
be used at extreme operating temperatures or experience frequent and wide temperature cycling eects, the
cable/connector attachment can be strengthened with
an RTV adhesive (see Plastic Connector ing Instructions
for more detail). The connectors are made of a ame retardant VALOX UL94 V-0 material (UL le # E121562).
SIMPLEX CONNECTOR STYLES
HFBR-4501Z/4511Z – Simplex
DUPLEX CONNECTOR STYLES
HFBR-4506Z – Duplex
HFBR-4526Z
Duplex connectors provide con venient duplex cable
termination and are keyed to prevent incorrect insertion
into duplex congured modules. The duplex connector
is compatible with dual combina tions of horizontal, vertical or tilted packages (e.g., two horizontal transmitters,
two vertical receivers, a horizontal transmitter with a
horizontal receiver, etc.). The duplex non-latching connector is available in parchment, o-white (HFBR-4506Z).
HFBR-4516Z – Duplex Latching
, HFBR-4525Z
The simplex connector provides a quick and stable connection for applications that require a component-toconnector retention force of 8 Newtons (1.8 lb.). These
connectors are available in gray (HFBR-4501Z) or blue
(HFBR-4511Z). The simplex connector is compatible with
horizontal or vertical or tilted packages.
HFBR-4503Z/4513Z – Simplex Latching
HFBR-4525Z
The simplex latching connector is designed for rugged
applications requiring a greater retention force — 80
Newtons ( 18 lb.) — than provided by a simplex nonlatching connector. When inserting the simplex latching
connector into a module, the connector latch mechanism should be aligned with the top surface of the
horizontal package, or with the tall vertical side of the
vertical package or with top surface of tilted package.
Misalignment of an inserted latching connector into
either module will not result in a positive latch. The connector is released by depressing the rear section of the
connector lever, and then pulling the connector assembly away from the module housing.
The simplex latching connector is available in gray (HFBR-4503Z) or blue (HFBR-4513Z).
DUPLEX
CRIMP RING
HFBR-4526Z
The duplex latching connector is designed for rugged
applications requiring greater retention force than
the nonlatching duplex con nector. When inserting the
duplex latching connector into a module, the connector
latch mechanism should be aligned with the top surface
of the dual combination of horizontal, vertical or tilted
packages. The duplex latching connector is available in
gray (HFBR-4516Z).
Feedthrough/Splice
HFBR-4505Z/4515Z Bulkhead Adapter
The HFBR-4505Z/4515Z adapter mates two simplex
connectors for panel/bulkhead feedthrough of HFBR4501Z/4511Z terminated plastic ber cable. Maximum
panel thickness is 4.1 mm (0.16 inch). This adapter can
serve as a cable in-line splice using two simplex connectors. The adapters are available in gray (HFBR-4505Z) and
blue (HFBR-4515Z). This adapter is not compat ible with
POF duplex, POF simplex latching, or HCS connectors.

Step-by-Step Plastic Cable Connectoring Instructions
The following step-by-step guide describes how to terminate plastic ber optic cable. It is ideal for both eld and
factory installation. Connectors can be easily installed
on cable ends with wire strippers, cutters and a crimping
tool.
Finishing the cable is accom plished with the Broadcom
AFBR-4594Z Polishing Kit, consist ing of a Polishing Fixture,
600 grit abrasive paper and 3 µm pink lapping lm (3M
Company, OC3-14). The connector can be used immediately after polishing.
Materials needed for plastic ber termination are:
1. Broadcom Plastic Optical Fiber Cable (Example: HFBRRUS500Z, HFBR-RUD500Z, HFBR-EUS500Z, or HFBREUD500Z)
2. Industrial Razor Blade or Wire Cutters
3. 16 Gauge Latching Wire Strippers (Example: Ideal
StripmasterTM type 45-092).
4. HFBR-4597Z Crimping Tool
5. AFBR-4594Z Polishing Kit
6. One of the following connectors:
a) HFBR-4501Z/4503Z Gray Simplex/Simplex Latching
Connector and HFBR-4525Z Simplex Crimp Ring
b) HFBR-4511Z/4513Z Blue Simplex/Simplex Latching
Connector and HFBR-4525Z Simplex Crimp Ring
Step 2
Place the crimp ring and connec tor over the end of the
cable; the ber should protrude about 3 mm (0.12 in.)
through the end of the connector. Carefully position the
ring so that it is entirely on the connector with the rim of
the crimp ring ush with the connec tor, leaving a small
space between the crimp ring and the ange. Then crimp
the ring in place with the crimping tool. One crimp tool is
used for all POF connector crimping requirements.
For applications with extreme temperature operation
or frequent temperature cycling, improved connector
to cable attachment can be achieved with the use of an
RTV (GE Company, RTV-128 or Dow Corning 3145-RTV)
adhesive. The RTV is placed into the connector prior to
insertion of the ber and the ber is crimped normally.
The connector can be polished after the RTV has cured
and is then ready for use.
Note: By convention, place the gray connector on the transmitter cable end and the blue connector on the receiver cable
end to maintain color coding (dierent color connectors are
mechanically identical).
c) HFBR-4506Z Parchment (o-white) Duplex Connector
and HFBR-4526Z Duplex Crimp Ring
d) HFBR-4516Z Gray Latching Duplex Connector and
HFBR-4526Z Duplex Crimp Ring
Step 1
The zip cord structure of the duplex cable permits easy
separation of the channels. The channels should be separated a minimum of 100 mm (4 in) to a maximum of 150
mm (6 in) back from the ends to permit connectoring
and polishing.
After cutting the cable to the desired length, strip o
approxi mately 7 mm (0.3 in.) of the outer jacket with the
16 gauge wire strippers. Excess webbing on the duplex
cable may have to be trimmed to allow the simplex or
simplex latching connector to slide over the cable.
When using the duplex connector and duplex cable, the
separated duplex cable must be stripped to equal lengths
on each cable. This allows easy and proper seating of the
cable into the duplex connector.
Simplex connector crimp rings cannot be used with duplex
con nectors and duplex connec tor crimp rings cannot be
used with simplex connectors because of size dierences.
The simplex crimp has a dull luster appear ance; the duplex
ring is glossy and has a thinner wall.
5
Page 6
Step 3
Any excess ber protruding from the connector end may
be cut o; however, the trimmed ber should extend at
least 1.5 mm (0.06 in) from the connector end.
Insert the connector fully into the polishing xture with
the trimmed ber protruding from the bottom of the
xture. This plastic polish ing xture can be used to polish
two simplex connectors or sim plex latching connectors
simultane ously, or one duplex connector.
Note: The four dots on the bottom of the polishing xture
are wear indicators. Replace the polishing xture when any
dot is no longer visible. Typically, the polishing xture can
be used 10 times; 10 duplex connectors or 20 simplex connectors, two at a time.
Place the 600 grit abrasive paper on a at smooth surface,
pressing down on the connector, polish the ber and the
connector using a gure eight pattern of strokes until
the connector is ush with the bottom of the polishing
xture. Wipe the connector and xture with a clean cloth
or tissue.
Step 4
Place the ush connector and polishing xture on the dull
side of the 3 µm pink lapping lm and continue to polish
the ber and connector for approximately 25 strokes. The
ber end should be at, smooth and clean.
This cable is now ready for use.
Note: Use of the pink lapping lm ne polishing step results in
approximately 2 dB improve ment in coupling performance
of either a transmitter-receiver link or a bulkhead/splice over
a 600 grit polish alone. This ne polish is comparable to the
Broadcom factory polish. The ne polishing step may be
omitted where an extra 2 dB of optical power is not essential,
as with short link lengths. Proper polishing of the tip of the
ber/connector face results in a tip diameter between 2.5
mm (0.098 in.) minimum and 3.2 mm (0.126 in.) maximum..
