1.4 Cyan L-AMP Shelf
The Cyan Z-Series Lambda Amplifier (L-AMP) is a fully self-contained 1 RU module that functions as a
bi-directional mid-span optical amplifier / repeater. Each L-AMP shelf supports bi-directional physical
layer amplification of multiple DWDM wavelengths where node-to-node optical spans are greater than
80 kilometers.
Traffic enters the L-AMP shelf from an East or West Cyan node, is appropriately attenuated, and processed
through a high performance two-stage Erbium Doped Fiber Amplifier (EDFA) for transmission to an
upstream Cyan Z-Series platform.
The shelf also provides a 1510nm add/drop port to support an Optical Supervisory Channel (OSC) carrying
Ethernet traffic for OAM.
The L-AMP shelf has all access on the front. It is designed to fit into 19-inch equipment racks, but has
extension mounting brackets for 23-inch rack installation.

Connectors on the L-AMP shelf include four types:
• System alarm outputs
• Environmental alarm inputs and outputs
• Ethernet ports (2)
• RS-232 port (reserved for future use)
