Description

Compact 70x90 mm Variable Gain EDFA

F-tone's Compact 70x90 mm Variable Gain (VG) EDFA is a micro processor-controlled module for C-band amplification. The Compact VG module is packaged in a 70x90 mm amplifier package, providing drop-in replacement software and hardware compatibility to line cards already designed to accommodate fixed gain EDFA.

   Features

  • Up to 15 dB dynamic gain range with excellent gain flatness
  • Up to 21 dBm output power
  • Low noise figure over a large dynamic range
  • Fast transient suppression
  • Supports FG amplifier with VOA configurations 
  • RS232 and I2C communication
  • Laser safety - Class 1M

   Applications

  • Long-haul, regional, and metro WDM networks
  • Booster, in-line and pre-amplifier applications
  • ROADM system requiring full East/West separation
  • Improved link budget and OSNR-sensitive applications
  • Small footprint and low power consumption systems
