Compact Variable Gain EDFA
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

Hybrid Raman-EDFA
F-tone's Hybrid Raman-EDFA module enables cost-effective deployment of ultra-long haul networks as well as the extension of existing long-haul, regional and metro networks, without the need for 3R O-E-O regeneration. The Hybrid module consists of a counter-propagating Raman pump unit and a variable gain (VG) EDFA.
Variable Gain Dual Stage EDFA
F-tone's Variable Gain Dual Stage EDFA provides flattened gain across the C-band, low noise figure, and a large dynamic gain range (up to 15 dB). The product includes advanced features such as comprehensive transient control, tunable mid-stage access (MSA) loss, and gain tilting functionality. The Variable Gain Dual Stage EDFA can be implemented in all network segments (long-haul, regional, metro and access) and for all network applications (telecom, cable and enterprise).
