10%/90% coupler
Environmental & Mechanical Stability
Good Channel-to-channel Uniformity
The AOM is installed in fiber laser cavity
The coupler is a 2x2 1310 nm/1490 nm/1550 nm 50/50 three window coupler
200 GHz L -band 40 CH Thermal/Athermal AWG Optical Switch/VOA 10%/90% couplerThe Athermal AWG (AAWG) have equivalent performance to standard Thermal AWG (TAWG) but require no electrical power for stabilization. They can be used as direct replacements for Thin Film Filters (Filter type DWDM module) for cases where no power is available, and are suitable for outdoor applications over 30 to +70 degree in access networks. WDMs Athermal AWG (AAWG) provide excellent optical performance, high reliability, ease of fiber handling and
