SLQS28-2733-LRBD is single fiber optical transceiver module are designed for use in 100 Gigabit Ethernet links over 10km single mode fiber. The module incorporates one channel optical signal and operates on 1271nm and 1331nm wavelength.

The modules compliant with the 100G Single Lambda MSA standard and adopts the standard QSFP28 package. The modules realize a single fiber bi-directional full-duplex transmission link. The electrical interface complies with IEEE 802.3BM CAUI-4 standard and adopts 4*25G NRZ encoded signals, which is fully compatible with the electrical interface side of the existing 100G QSFP28 dual-fiber solution. PAM4 encoded signal with 53.125G baud rate (bit rate: 106.25GB /s) on the optical interface is mainly used in 100G Ethernet, 100G OTU4 and metro networks.
