Prisma II EDFAs
 Prisma II Optical Amplifiers offer a wide range of configurations and output
powers for architectural flexibility.
 Erbium-doped fiber amplifier modules are available in two categories:
Broadcast and Narrowcast Gain-Flattened.
 Broadcast EDFAs are typically used for the amplification of broadcast
signals which are carried by a single optical channel anywhere between
1530 nm and 1565 nm
 Narrowcast Gain Flattened EDFAs are designed for use in multiple
wavelength systems. This highly versatile EDFA maximizes system
performance and flexibility by providing constant gain control while
maintaining gain flatness for up to 40 wavelengths
