Description

Farsince 100G QSFP28 Active Direct Attach Cable is a shielded twinax assembly with integrated signal conditioning to maintain eye margins over copper runs. Both ends present hot‑pluggable QSFP28 connectors and carry four 25G NRZ lanes (100G aggregate) for direct connections between TOR switches, server adapters and storage platforms. Designed for short‑reach 100G Ethernet inside racks or between adjacent cabinets, the cable delivers deterministic latency and straightforward deployment without the power and management overhead of optics.

The 30 AWG construction and PVC (OFNR) jacket support a 33 mm minimum bend radius for clean routing in dense cable trays, while low‑power electronics limit consumption to 1.5 W per end. Pull‑tab latches simplify service operations, and the assembly aligns with QSFP28 MSA mechanics and SFF‑8665. Each unit is electrically tested for insertion loss and crosstalk. Farsince can provide multi‑vendor port coding, custom lengths and private labeling with lot‑level documentation to support volume rollouts in enterprise, cloud and edge environments.
