The SO-QSFP28-CWDM4 is a QSFP28 form-factor transceiver for 100 Gbps 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 is based on the 100G CWDM4 MSA industry standard with an optical performance enabling distances of up to 2km over a SingleMode (SM) fiber.
As stipulated in the CWDM4 MSA, 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) for SR4’based transceivers. 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-CWDM4 uses four CWDM channels/lanes @ 25.78Gbps to transport the Ethernet signal. Digital diagnostics functions (DDM) are available via an I2C interface, as specified by the QSFP28 MSA.
