Finisar RDH90165/1 Optical Transmission / Ethernet Optical Transmission Module

The Finisar RDH90165/1 is a 10 Gigabit XFP optical transceiver corresponding to the Finisar FTLX1412D3BCL series, built for 10GBASE-LR links over single-mode fibre at a 1310nm wavelength. This class of Finisar XFP module supports transmission distances of up to around 10km over standard single-mode fibre via an LC connector, and includes digital optical monitoring (DOM) so installers can check transmit and receive optical power, bias current and temperature in real time without taking the link down. Rated for 0 to 70C operation, it is a widely deployed module in carrier and enterprise 10-Gigabit Ethernet backbones. The RDH-prefixed part number is the stock code under which this Finisar module was supplied into Ericsson network equipment, so it typically surfaces from decommissioned Ericsson transmission and switching infrastructure. Tech-Star (UK-based, shipped worldwide) supplies this RDH90165/1 as a tested, working XFP module suitable for network engineers and telecom resellers needing a spare or like-for-like replacement for 10G single-mode fibre links.
