Prisma High-Density Gain-Flattened EDFA Data Sheet
Available Languages
Description
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. The gain-flattened EDFA incorporates an optical filter to eliminate variations in gain across the C-band.
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 constant power or 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)

Notes:
1. The output power is measured after a typical jumper loss of 0.2 dB.
2. Nominal (Design) Gain used for specification compliance.
3. For output power range from 3dB below nominal maximum power to maximum power.
4. Non-condensing external to the Prisma II or XD chassis.
