HANSUN The common types of BiDi transceivers used in today’s networks are 1G/10G BiDi SFPs. The most common optical wavelengths for this transceiver are 1310/1490 nm, 1490/1550 nm, and 1310/1550 nm. They are designed for 1/10 GB deployment and can reach up to 80km distance. BiDi variants are also available for the form factor XFP X2 for 10G, GBIC for 1G.
The 25G SFP28 BiDi transceiver supports connections up to 10km over single-mode fiber and uses LC connectors. The wavelengths are 1330TX/1270RX and 1270TX/1330RX.
The 100G QSFP28 BiDi CWDM4 transceiver supports connections up to 2km over single-mode fiber and uses LC connectors. The wavelengths are 1271 nm, 1291 nm, 1311 nm, and 1331 nm.
The 40GBase QSFP+ BiDi has two 20G channels that support connections up to 100 meters on OM3 MMF and up to 150 meters on OM4 MMF. It uses an LC Duplex connector and the wavelength is 850nm. QSFP+ BiDi is a cost-effective solution for a 10G to 40G upgrade.
