Y-Cable Splitter Job Aid - Adtran

Product P/N: 1184015L1
DESCRIPTION
The Y-Cable Splitter connects two optical devices to a single fiber
span, or routes a single optical signal onto two different fibers.
The Y-cable can only transmit one signal at a time (does not
provide a multplexing function), so use with two optical devices
is best accomplished in a redundant configuration where only
one device is online at any one time.
The Y-cable is bi-directional and can be used in either the
Transmit (Tx) or Receive (Rx) direction, at either end of a fiber
span, depending on the function it is to provide.
Y-Cable Splitter
The Y-cable supports the following features:
♦ Fiber leads are 1 meter each in length
♦ SC connectors
♦ Optical loss of 0.5 dB

CONFIGURATION OPTIONS
The Y-cable can be used in any application where it is desirable
to split an optical source. The following two configurations are
provided as examples of possible applications:
♦ Single span redundancy
♦ Test kit lead
Single Span Redundancy
When an existing optical path is upgraded from a stand-alone configuration to a redundant configuration, using Y-cables can
eliminate the need to run new fiber spans for the Protect modules. Installing Y-cables at each end of the existing spans allows
Working and Protect modules to share the same fibers.

Test Kit Lead
Installing a Y-cable between the existing fiber and optical device enables a test kit to be attached to the second lead of the Y-cable.
In this configuration, a test kit can be attached without disrupting traffic.

PRE-INSTALLATION
Inspect the Y-cables. If damaged, file a claim with the carrier and
then contact ADTRAN Customer Support.
Identify the fiber leads on the Y-cables to be used for Tx and Rx
as necessary for the intended application.
INSTALLATION
The following installation procedure is an example of how to
install four Y-cables into a legacy, stand-alone configuration
when upgrading to a redundant configuration. Refer to “Single
Span Redundancy” for details.
NOTE: Although the OPTI-3 is cited in this procedure, the Y-cable
can be used with most ADTRAN optical equipment.
CAUTION: This procedure interrupts traffic. Near-end and
far-end upgrades should be coordinated to minimize
the resulting loss of service.
This procedure involves two modules and two Y-cables
at each end of the fiber spans. Make certain each item
is clearly identified.
To upgrade from stand-alone to redundant, using Y-cables
instead of two new fiber spans, complete the following steps:
1. Remove the stand-alone module from the legacy system.
2. Disconnect the Tx fiber from the legacy module.
NOTE: The legacy module becomes the Working module in the
redundant configuration.
3. Connect the single-fiber of Y-cable #1 to the Tx fiber.
4. Connect one of the dual-side fibers of Y-cable #1 to the
Working module Tx jack.
5. Disconnect the Rx fiber from the Working module.
6. Connect the single-fiber of Y-cable #2 to the Rx fiber.
7. Connect one of the dual-side fibers of Y-cable #2 to the
Working module Rx jack.
8. Re-install the Working module.
NOTE: If all connections have been made properly, the module
should turn up as normal.
9. Connect the second Tx fiber (Y-cable #1) and Rx fiber
(Y-cable #2) to the new, Protect module.
10. Install the Protect module.
11. Complete the steps at the far end. Repeat steps 1 – 10,
substituting Y-cable #3 for Y-cable #1, and Y-cable #4 for
Y-cable #2 in the instructions.
