The Prisma II optical network allows for best in class architectures with increased reliability, scalability, and cost-effectiveness. The High Density (HD) Erbium Doped Fiber Amplifier (EDFA) is designed to fit into a Prisma XD chassis or a standard full height Prisma II chassis (with the use of a host module). Up to two HD EDFA modules can be populated into a host module which requires a single service slot in the Prisma II chassis.
Figure 1. High Density EDFA
Features
• EDFA modules for optical amplification
• High density design allowing up to 16 EDFAs in a Prisma II XD chassis or up to 24 in a full height Prisma II chassis with redundant power supplies
• Energy-efficient design with low power consumption
• EDFA modules have both constant power and constant gain modes of operation
• Master/Slave redundancy using Controller Area Network with no external wiring needed
• Multiple setup and control options
– Local Control via Local Craft Interface (LCI)
– Local monitoring via Intelligent Communications Interface Module (ICIM)
– Remote monitoring via ROSA status monitoring and control element manager

Notes:
1. The output power is measured after a typical jumper loss of 0.2 dB.
2. Gain flatness measured under default gain conditions.
3. Non-condensing external to the Prisma II or XD chassis.
