Release Information

Description
NCS2K-MF-8x10G-FO Cisco NCS 2000 Release 12.3

The MPO-12 to 8-LC fan-out module is a double slot module with two MPO-12 connector (COM) and eight LC duplex connectors (Port-i-TX/RX). It contains 16 photodiodes to monitor the power of the channel input ports.

_15216-PP-4-SMR

 Cisco NCS 2000 Release 12.3

The _15216-PP-4-SMR patch panel connects up to four 40-SMR2-C cards in a four-degree mesh node. The optical splitters inside the patch panel forward the output signal (EXP-TX port) of the 40-SMR2-C card on each side of the mesh node to the input port of the 40-SMR2-C cards on the other three sides of the mesh node.

NCS2K-MF-CL-SC Cisco NCS 2000 Release 12.2

A new passive module, the C and L-band combiner and splitter, is introduced.

The L-band addition for non-Raman assisted optical links requires a C and L optical combiner for expansion. The NCS2K-MF-CL-SC module allows Cisco to introduce any future L-band transmission system onto the existing NCS 2000 deployments.

Passive devices are used to build the optical network system. You can install them on:

  • 19 inch (482.6 mm) or 23 inch (584.2 mm) EIA standard racks

  • 19 inch (482.6 mm) IEC rack

  • 600 mm x 600 mm or 600 mm x 300-mm ETSI rack

The following table lists the supported passive chassis and passive devices:
