800G OSFP to 4x200G OSFP-RHS Passive Direct Attach Cable

This cable connects one 800G OSFP host port to four 200G OSFP-RHS ports. The 16 differential pairs on the OSFP end are split into four groups of eight lanes, each terminating at one OSFP-RHS connector. Each lane carries a 50 or 100Gb/s PAM4 signal at 53.125 GBd/s, in accordance with IEEE P802.3ck.

Each of the five connector ends carries an EEPROM accessible over I2C, allowing product information to be read or written independently per port. The cable is available in three lengths: 0.5m and 1m using 30AWG wire, and 2m using 26AWG wire. Operating case temperature range is 0°C to 70°C; storage temperature range is -20°C to 85°C. Operating humidity is rated up to 85% RH (non-condensing).

The OSFP end uses the CTHS (Close Top Heat Sink, finned-top) housing. The four OSFP-RHS ends use the RHS (Riding Heat Sink, flat-top) housing, which sits lower than the CTHS housing of the same connector type. The cable complies with OSFP MSA and IEEE P802.3ck, and is RoHS compliant.
