Products; hot type AWG device uses thermal AWG module with a unique package design based on planar optical waveguide (PLC) silicon substrate grating technology, the key modules, reducing power consumption, the AWG kit, use reliable thermal plastic, low thermal conductivity and precise working temperature control for accurate channel coupling, low insertion loss, high channel isolation, and high stability. Features: Channel spacing 100GHZ (0.8 nm) up to 48 channels can be reused; low insertion loss, insertion loss ≤5dB, a typical value of 4.5dB, high channel isolation, adjacent isolation ≥25dB; non-adjacent isolation ≥ 35dB high stability, dual power supplies, hot-swappable, 1 + 1 protection; perfect indicator status;
