QSFP28 100GE-eLR4 OTU4 SM 13xxnm 20km 10dB LC
A QSFP28 form-factor transceiver for 100G Ethernet and OTU4 applications.
Product information
The SO-QSFP28-LR4-20D is a QSFP28 form-factor transceiver for 100G Ethernet and OTU4 applications. It is intended for use in inter- and intra-connect applications within and between data centers between switches, routers, storage equipment etc. The optical performance supports optical distances up to 20km over a SingleMode (SM) fiber according to the 100G 4WDM-20 MSA.
For Ethernet services, Forward Error Correction (FEC) is required to be implemented by the host in order to ensure reliable system operation. The FEC type shall be as defined in IEEE802.3bj, i.e. Reed Solomon RS(528,514). The optical parameters will provide a bit error ratio (BER) of 5 x 10-5. FEC will render in the required BER of better than 1 x 10-12.
SO-QSFP28-LR4-20D uses four optical channels/lanes @ 25.78Gbps to transport the Ethernet signal and 27.95Gbps for the OTU4 signal. Digital diagnostics functions are available via an I2C interface, as specified by the QSFP28 MSA.
