2. Introduction

2.1 The Complete Fiber Solution

CertiFiber™ is an advanced handheld certification tool for fiber links, and is designed to be the complete solution for professional cable installers, service providers, and network administrators.

With the push of a button, CertiFiber

certifies two multimode fibers simultaneously at both wavelengths.

Rather than just providing a number,

CertiFiber analyzes the fiber link and determines whether cabling and network standards are met.

The CertiFiber main unit and CertiFiber

Remote have an optical source that provides a consistent calibrated dual-wavelength light. The level of light injected into or emerging from the fiber network can be measured at any point so that the performance of fiberoptic transmission paths and equipment can be accessed quickly and accurately.

The CertiFiber helps you identify faulty

patch cables, failing splices, and bad couplers and connectors.

CertiFiber also accurately tests the link’s

propagation delay, which is then used to calculate length.

CertiFiber incorporates a graphical user

interface, display, menus, arrow keys and descriptive menu options that guide you

CERTIFIBER™

Page 10

quickly and easily through the completely automated process of certifying or trouble- shooting fiberoptic cabling systems.

2.2 Standard Features

•Certifies a duplex fiber link (two fiber cables) simultaneously.

•Measures Optical Power Loss in the direction of data transmission for both multimode wavelengths on two fiber cables without changing connectors.

•Measures Length and Propagation Delay for a dual fiber cable.

•Makes bidirectional measurements for duplex fiber links.

•Utilizes preprogrammed test templates to easily certify fiberoptic cabling to industry or network standards.

•Pinpoints the margin available on the tested cable above and beyond the PASS/FAIL requirements.

•Stores a thousand autotest results in memory with user-friendly alphanumeric names, job names, and unique time- and date-stamps.

•

Transmits light continuously or modulated.

•Downloads stored test results to a computer database for printing and professional record management.

•

Includes a custom-tailored, non-removable impact cover for added protection.

CAUTION!

All connectors and fiber-end faces need to be clean prior to testing. Use the appropriate optical cleaning supplies to keep connectors and adapters free from contamination.

Both CertiFiber units come with covers on their ST connectors to protect the connectors from dirt and other foreign matter. Keep the connectors covered when the units are not in use. This helps to ensure that contaminants do not affect test measurements.

4.1 Setting the Reference

4.1.1 INN

ORMALOPERATION

Accurate, repeatable measurements of optical power and signal loss are fundamental for the installation and maintenance of fiber optics.

To make an accurate measurement, you need to know the loss in your attached launch cable and the power being transmitted. (The launch cable used to set the reference value should be the same type of fiber as the cables to be tested and certified, either 50/125 or 62.5/125.)

The reference value must be stored before a loss measurement can be calculated. CertiFiber requires the reference value to compensate for the signal loss in the launch cable. This value is then subtracted from the actual

CERTIFIBER™

Page 34

measured value to determine loss.

Once the reference value is established, consistent readings for loss, delay, and length measurements are ensured.

To set the reference value, take these steps:

1. Connect CertiFiber and CertiFiber Remote using the ST-ST launch cables and couplers as shown at right.

2. Press Shift + Autotest to record the reference value. The Reference screen shown below will appear briefly. Once the reference data has been saved, the CertiFiber logo screen will be displayed.

3. Remove the couplers.

NOTES

Once the reference value has been set, make sure that both launch cables remain attached to the CertiFiber units. Try to remove the coupler without disturbing these connections.

If the test configuration changes, a new reference

value needs to be established.

CHAPTER 4: Operation: Automatic Measurements

1-m Launch Cable

Coupler

Page 35

CertiFiber will store a separate reference value for each wavelength.

The new reference value will be subtracted from the actual measured value to determine loss.

CertiFiber will store reference data for up to five CertiFiber Remote units and one loopback setup (see the next section).

NOTE

To ensure consistently accurate measurements, the reference value must be set each calendar day that CertiFiber is used. The reference value expires each day at midnight.

4.1.2 INL

OOPBACKMODE

If a single cable needs to be measured, the reference value can be set for a single launch cable. To do so, take these steps:

1. Attach one end of the cable to the CertiFiber main unit’s TX1 connector, and the other end to the RX2 connector, as shown at right.

2. Use a coupler to connect the Launch cables.

3. Press Shift + Autotest to record the reference value.

4. Remove the coupler without disturbing the connection to the CertiFiber.

CHAPTER 4: Operation: Automatic Measurements

Page 39

During Autotesting, CertiFiber measures a cable’s Loss, Length, and Delay:

Optical Power Loss is a measurement of the signal loss in a cable. A signal is injected into the fiber cable by the Remote unit. CertiFiber measures the received signal to determine loss. It displays the loss in decibels (dB), as well as the margin values, for both wavelengths.

Length measurements are derived from the propagation-delay results by using the cable’s GRI (Graded Refractive Index) at the appropriate wavelength. CertiFiber measures the full length of the fibers under test. (See

Section 3.5

for information on how to change the GRI values.) In the Autotest Results screen, the length is displayed in meters or feet depending on how your unit is set up. (See

Section 3.2

Propagation Delay is a measurement of the time required for a signal to advance from one end of the circuit to the other. When measuring propagation delay, CertiFiber measures the round-trip delay through both fibers, and then divides the result by two, assuming that the cables are equal in length. Propagation delay cannot be measured on a single fiber; duplex fibers must be used. The Autotest Results screen displays the Propagation Delay in nanoseconds (ns).

CAUTION!

All connectors and fiber-end faces need to be clean prior to testing. Use the appropriate optical cleaning supplies to keep connectors and adapters free from contamination.

5.1 Power Loss

The proper operation of a fiber network can be affected by the operation of its active components, such as transmitters and receivers. Excessive loss could actually be a result of a transmitter launching light at an unacceptable power level. Transmitters can also deliver too much light into the fiberoptic cable, causing the receiver to overload.

You can use CertiFiber’s Power Meter function to quickly verify and correct cabling and equipment problems. For both test wavelengths, Power Meter reports the overall power, the previously stored reference value, and the loss.

To perform a Power Meter test, take these steps:

1. Connect CertiFiber directly to a cable or use a launch cable to connect to the equipment to be tested.
