Optical interfaces (AMS unit/X5IP card)

Overview

Two aggregate STM-1 interfaces are available on the AMS main board and one-gigabit interface is available on the X5IP option card.

Optical connectors

The optical interfaces can be equipped with various SFPs (Small Form-Factor Pluggable Optics). All SFPs are equipped with LC connectors. The next figure shows the variable SFP module system.

NOTES:

• Please note that Alcatel-Lucent warranty is contingent upon the use of Alcatel-Lucent specified SFPs for 1643 AMS. Use of other SFPs is not approved by Alcatel-Lucent and is fully at the customer's own risk. Any warranty obligation of Alcatel-Lucent is extinguished when non-Alcatel-Lucent specified SFPs are used.

• It is not mandatory to have an LBO (Lightguide Build-Out) between the SFP and the connected optical cable. However, in the case of measurements with optical loops and/or connecting power meters an LBO (15 dB) can be required. An LBO can also be necessary to ensure the correct input power (see chapter 8, section Connecting the fiber cables).

• If no SFPs are used, the optical line interfaces must be equipped with “Dust Plugs” (LPN: 700159437) to prevent dust and EMC emission. The dust plugs are part of the 1643 AMS delivery.
