Finisar HFE4080-321 1pc(s) Grey fiber optic adapter

850nm, VCSEL, 1.25 Gbps 850nm, TO-46 Flat window Component, no back monitor, unattenuated (HFE4080-321)

The HFE4080-321 is a high-performance 850 nm VCSEL (Vertical Cavity Surface-Emitting Laser) packaged for high-speed data communications.The HFE4080-321 is a high radiance VCSEL designed to convert electrical current into optical power that can be used in fiber optic communications and other applications. As the current varies above threshold, the light intensity increases proportionally.
