W.L. Gore & Associates IBN4800-01 Rev C QSFP QDR InfiniBand Cable, 1m, Lot of 5: This is a 1-meter QSFP-to-QSFP InfiniBand cable assembly designed for QDR (Quad Data Rate) InfiniBand fabrics at 40Gb/s aggregate (4x 10Gb/s). Manufactured by W.L. Gore & Associates, who supply integrated copper and fiber assemblies into the InfiniBand ecosystem. This is a Rev C revision of the IBN4800-01 part. This listing is for five (5) refurbished units.
Engineering Context
QDR InfiniBand operates at 10Gb/s per lane across four lanes for a 40Gb/s aggregate (32Gb/s data after 8b/10b encoding). At 1 meter, QSFP QDR cables are typically passive copper assemblies; T.E.S can confirm the exact construction (passive copper versus active fiber) of any specific lot on request before shipment. The integrated EEPROM identifies the cable to the host adapter so the link can come up without a vendor-specific transceiver. The QSFP form factor follows SFF-8436.
Deployment & Use Cases
QDR InfiniBand HPC clusters using Mellanox IS50xx-series switches and ConnectX-2 / ConnectX-3 host adapters. Short intra-rack server-to-switch links where 1 m is sufficient. Replacement of failing 1 m QDR cables in legacy clusters that cannot easily be migrated to FDR or EDR. Lab and test-rig setups for QDR InfiniBand validation.
Technical Specifications

Compatibility & Hard Constraints
Compatible with Mellanox IS50xx QDR switches and ConnectX-2 / ConnectX-3 host adapters operating in QDR mode. Will physically mate with QSFP+ FDR ports and the link will negotiate down to QDR (40Gb/s); it will not deliver FDR or EDR rates. Not a breakout cable; QSFP-to-QSFP only. Not compatible with QSFP28 100GbE Ethernet ports at full rate. Verify cable construction (passive copper or active fiber) with T.E.S before deployment if your fabric design depends on a specific construction.
Why Choose T.E.S IT-SOLUTIONS
