Finisar is a leading manufacturer of optical communication components and subsystems, producing a wide range of SFP, SFP+, QSFP, and XFP transceivers for enterprise and data centre networking.

Copper transceivers (e.g. SFP-T) provide direct-attach copper connectivity over standard RJ45 cabling, typically supporting 10/100/1000BASE-T Ethernet at distances up to 100 metres.

850nm transceivers (e.g. 1000BASE-SX, 10GBASE-SR) are designed for multimode fibre applications, ideal for short-reach intra-building links, typically supporting distances of up to 300 metres on OM3 multimode fibre.

1310nm transceivers (e.g. 1000BASE-LX, 10GBASE-LR) are designed for single-mode fibre applications, supporting longer-reach links typically up to 10 kilometres.

Typical Specifications (varies by model):
Form Factor: SFP / SFP+
Wavelengths Available: Copper (RJ45), 850nm (multimode), 1310nm (single-mode)
