QSFP28 100GE-eLR4 SM 13xxnm 20km 11.2dB LC
A QSFP28 form-factor transceiver for 100G Ethernet 100GBASE-eLR4 applications.
Product information
The SO-QSFP28-LR4-20L is a QSFP28 form-factor transceiver for 100G Ethernet 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.
Forward Error Correction (FEC) is required in the host equipment in order to ensure reliable system operation at the specified distance. The FEC type shall be as defined in IEEE802.3bj, i.e. Reed Solomon RS(528,514). The below 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-LR4-20L uses four optical channels/lanes @ 25.78Gbps to transport the Ethernet signal. Digital diagnostics functions are available via an I2C interface, as specified by the QSFP28 MSA.
