F-tone's 70x90 mm Fixed Gain EDFA product line supports a full range of C- or L-band fixed gain WDM EDFAs, as well as narrow band, CWDM and single channel EDFAs. The products support either cooled or uncooled pumps, allowing the optimal combination of size, power consumption and performance to be achieved for each application.

High Power Variable Gain / Fixed Gain EDFA:F-tone's High Power Variable Gain / Fixed Gain EDFA module provides up to 26dBm output power using standard telecom grade single-clad broadband technology. This high output power is critical in applications requiring an improved optical signal to noise ratio (OSNR), such as long repeaterless links, long span masking in multi-span links, and high capacity systems.

Raman Amplifier Module:F-tone's Raman amplifier module is an intelligent pump unit for distributed Raman amplification. The Raman amplifier module can accommodate two or three pumps (multiple wavelengths) for C or L-band amplification, and includes full and comprehensive electronic control. The dual and triple-pump models have a maximum output power of 700 mW and 1 W, respectively. Using patent pending technology, the Raman pump unit can operate in full automatic gain control (AGC) mode, thus allowing the Raman gain to be set with an accuracy of +/-0.7 dB.
