Multiple Device Assemblies
PD-LD offers bi-directional laser modules, as well as laser combiners and triplexers, which combine 2 or 3 wavelengths respectively.
Bi-directional
PD-LD offers a family of bi-directional transmitter and receiver modules operating in the 1310 and 1550nm optical windows.
Laser Combiners
Laser combiners combine 2 emitters (e.g. two lasers with different wavelengths) into one fiber.
Triplexers
Triplexers combine 3 emitters, usually laser diodes, e.g., 1310 nm, 1490 nm and 1550 nm devices, so that all 3 are coupled to one fiber (SM or MM).
