QSFP-DD 400G-DR4 SM 1311nm 500m 3dB CMIS3 APC MPO
A 500m QSFP-DD form-factor transceiver for 400Gbps Ethernet applications over an 8 channel ribbon-fiber.
Product information
The SO-QSFP-DD-4C-DR4-M is a QSFP-DD form-factor transceiver for 400Gbps Ethernet applications. It is intended for use in data center interconnect between switches, routers, storage equipment etc. for optical distances up to 500m over a SingleMode (SM) ribbon fiber cable.
The electrical interface consists of eight 53.125G signals (400GAUI-8) that are converted to eight PAM4-modulated channels/lanes to transport the Ethernet signal. The transceiver can also be set in 4x100GAUI-2 mode (application code 2) to enable 400G to 4x 100G break-out configurations. Digital diagnostics functions are available via an I2C interface, as specified by the QSFP-DD MSA.
The optical interface to the transceiver is an MPO-8 or MPO-12 Angled Polished Connector (APC).
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 2.4 x 10-4.
The transceiver is compliant with Common Management Interface Specification CMIS3.0.
