Features of the 100G QSFP28 Bidi

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.

BIDI Transceivers or BWDM Transceivers (Bi-directional Wavelength Division Multiplexing) interface carries two distinct channels in different directions on a single strand of fiber. They must always be used in complementary pairs. BIDI Transceivers are a cost effective solution by doubling the capacity of an existing fiber infrastructure.
