DWDM Athermal Arrayed Waveguide Grating:Dense Wavelength Division Mux/Demultiplexer Athermal Arrayed Waveguide Grating(AAWG) Modules are part of a series of high performance products based on silica-on-silicon planar technology and a unique athermal packaging design requiring no electrical power, software or temperature control for a completely passive DWDM solution.

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.

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).

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.
