Splicing/Patch Panel TrayLoose tube Pigtails

The shelves are designed to be mounted in the FIST-GR Optical TerminationRack.

This shelf is designed to operate in ETSI1 climatic classes 3.1 - 3.3. This

covers weather-protected locations. This would typically be in exchanges,primary distribution points and the customers premises such as building

basements, telecommunications equipment rooms, computer rooms, etc.

The Shelf consists of a metal chassis with a drawer and accomodates a series ofhinged Patch Panel Trays to house splices, passive optical devices, receptaclesand connectorized pigtails.

The Patching Shelf allows for selective access for maintenance and upgradeswithout affecting live circuits.

Control on fiber management is maximised during installation, operation,maintenance and upgrade:

pigtail routing is controlled with bend controls on the Patch Panel Tray.

pigtail routing is controlled with bend controls in the transition from theTermination Rack side ducts towards the Patch Panel Trays.

Various connector receptacles (SC, FC, ST, E2000, etc.) can be easily installedand replaced in the Patch Panel Tray.

Sample description

The Shelf shall be mounted in the FIST-GR Optical Termination Rack.

The optical test sample shall be constructed in the following way:

Three (3) splicing/Patch Panel Trays are made active with 12 splices (between primarycoated fibers from loose tube to 900 m connectorized fibers) and 12 connections to 2.4mm reinforced patch cords, randomly distributed over the 3 trays. The fibers and patchcords are spliced and interconnected in such a way that the optical signal runssequentially through the selected fibers.

Test Procedure for addition of Loose Tubes and Patch Cord Cables

Open the shelf and hinge the trays.

Select one tray with active patch cords.

Add a new loose tube to the tray and plice 2 fibers to connectorized 900 m pigtails.

Add 2 patch cord cables to the tray and route the cables through the shelf.

Repeat this operation for the other 2 active trays.

Hinge and secure the trays.

Close the shelf.

Axial Pull on Pigtails

This test simulates the effect of pulling accidentally on the patch cords during

installation and re-entry. It is intended to stress the connections between pigtailsand shelf.



Three (3) splicing/Patch Panel Trays are made active with 12 splices (between primarycoated fibers from loose tube to 900 m connectorized fibers) and 12 connections to 2.4 mmreinforced patch cords, randomly distributed over the 3 trays. The fibers and patch cordsare spliced and interconnected in such a way that the optical signal runs sequentially throughthe selected fibers. The rest of the trays is loaded to full capacity with non-active fibers orconnectorized pigtails.

The optical signal will be monitored during the test at 1550 nm. Transient loss (see

page 17) and change in optical loss (see page 11) after the test will be checked. After completion of the test the pigtail attachment inside the shelf shall be checked for

cable pull-out.


11/68


Change in Optical Loss

This is the criterion test for optical measurements.


This is defined as a measured attenuation which is exhibited by stable transmissionmeasurements taken before and after a test.

It shall be measured using an optical source and a detector operating at 1310 nm and1550 nm.

The in and outgoing fibers of the test sample are spliced onto the connection fibers ofthe equipment. Splices shall be made using good-quality fusion splices.

During the test the optical signal in each fiber circuit shall be measured with the lightsource and detector at both wavelengths. A change of more than 0.3 dB per incomingfiber (during the test) from the initial value constitutes a failure.

After the test the optical signal in each fiber circuit shall be measured with the lightsource and detector at both wavelengths. A change of more than 0.2 dB per incomingfiber (after the test) from the initial value constitutes a failure.

All test samples will be installed with ruggedised internal optical pigtail cable of 2.4 mmoutside diameter containing a LSZH jacket and aramid strength member (Kevlar).

Testing is at room temperature4unless otherwise specified.When a test is specified at another temperature, samples shall be preconditioned for aperiod of 4 hours at that temperature.

Stabilisation periods between: test set-up and initial measurements, and after testing and final measurements,

shall be 2 hours ( 10 minutes).

Appearance

Three (3) splicing/Patch Panel Trays are made active with 12 splices (between pigtailcable fibers to the 900 m connectorized fibers) and 12 connections to 2.4 mmreinforced patch cords, randomly distributed over the 3 trays. The fibers and patchcords are spliced and interconnected in such a way that the optical signal runssequentially through the selected fibers.

Statistically based in-process control is practiced on all production lines whereappropriate, and is conducted on all parameters that govern end-productfunctionality and performance.

The frequency of such control and follow-up is evaluated during capabilitystudies on new equipment and shop floor implementation of the results isdetermined by the Quality Engineering Department.

In addition, the information is documented and controlled in the computerizedmanufacturing specification system.

Sourced Components

All suppliers of materials, components or systems manufactured outside the TycoElectronics facilities are included in the Vendor Evaluation and EducationSystem.

As a consequence of this, Tyco Electronics audits relevant suppliers on a regularbasis in order to ensure conformance TQM progress and conformance tospecification requirements.

Suppliers who do not reach the minimum level of approval are given help toimprove their systems.

Suppliers who do not reach the minimum level of approval are given help toimprove their systems.
