Functional Description:

The Tributary Optical Module 2.5G, referred to as TOM-MR-Dn-LR2 (n=18-37,40-59), is a field-replaceable 2.5G Small Form Factor Pluggable (SFP) module. It converts client side optical signals to and from serial electrical signals. TOM-MR-Dn-LR2s are hot-pluggable into any of the sub-slots in the TAM (TAM-4-2.5G, TAM-8-1G, and/or TAM-8-2.5GM) and are powered through the pluggable interface. 

TOM-MR-Dn-LR2 supports OC-48, OC-12, OC-3, STM-16, STM-4, STM-1, 2.5G Clear Channel, 1G Fibre Channel, 2G Fibre Channel, 1GbE, 1.25G Clear Channel, OTU1, ESCON 200M Clear Channel, InfiniBand 2.5G Clear Channel, Video HD1.485G, Video HD1.4835G, Video SD 270M, and/or Digital Video 6000 client signals. TOM-MR-Dn-LR2 port status LEDs are located on the TAM-4.

     Note: The TOM-MR-Dn-LR2 has fixed launch power and receiver sensitivity levels specified for this TOM at the OC-48/STM-16 rate, even                   when set to the lower bit rates (for example, OC-3/STM-1, 2GFC, and/or 1GbE). Launch power and receiver sensitivity should be                       taken into consideration when connecting to interfaces at lower rates; an optical attenuator may be required
