SFP28 WDM 25G module, LC Simplex, 20 km, 1330 nm — intended for a 25G link over a single fibre. The medium is G.652 single-mode fibre with an LC pair, or a single strand for bidirectional modules.

Specifications

Single-fibre modules only work in pairs: one end transmits on one wavelength, the other on the opposite one. Order both modules of the pair — on its own the link will not come up.

On compatibility. Switches from many vendors check the coding in the module EEPROM and may reject a third-party transceiver or accept it with a warning in the log. Tell us the switch or server model before ordering and we will supply a module with the right firmware and check it against the compatibility list.

How connectors map to speeds and why a link fails to come up is covered in our network cards and transceivers guide. Network cards with prices are in the network cards, transceivers and DAC selection.
