SFP, SFP+ & GBIC Transceiver Modules
DIRECTLY supplies a full range of fiber optic transceiver modules – SFP (1G), SFP+ (10G), SFP28 (25G) and QSFP / QSFP28 (40G/100G). These pluggable optical modules are often referred to as GBICs, and cover single-mode and multi-mode fiber across SR, LR, ER and ZR reaches, plus BiDi, CWDM and DWDM variants – everything you need to connect switches, routers and servers over fiber.
Each module is coded to work in switches and routers from 80+ networking brands, including Cisco, HPE, Juniper, Arista, Dell and D-Link. Built to MSA industry standards and recognized by your specific hardware, our modules deliver original-equivalent performance at a fraction of the branded price – typically 70–90% less, and over 90% versus premium brands such as Cisco. They install as a drop-in replacement and do not void your hardware warranty.
