Overview
Eoptolink's OSFP 1.6T DR8 family is the mainstream third-party option for 1.6T AI fabric links. The module runs eight electrical and eight optical lanes at 212.5 Gb/s (106 GBd PAM4), giving 1.6 Tb/s aggregate, and — crucially — it does not need optical-side FEC, which keeps both latency and power consumption down relative to retimed designs.
The ordering logic is simple: the fifth-to-seventh characters set the reach and the connector. EOLO-13T-5H-… is the 500 m DR8; EOLO-13T-02-… is the 2 km DR8-2. The suffix then selects MPO-16 (one 1.6T point-to-point link) or dual MPO-12 (two independent 800G-DR4 breakout links). The EOLO-16T-02-XXX is the CWDM 2xFR4 variant on duplex LC for structured cabling, and EOLO-85T-01-DX is the 850 nm multimode 2VR4 for short in-rack multimode runs.
Because the port semantics differ — 1 × 1.6TbE versus 2 × 800GbE on physically identical modules — the breakout decision has to be made before the fibre plant is ordered, not after. QS Compute supplies the full EOLO-13T / EOLO-16T / EOLO-85T set together with the matching OSFP224 cages, DACs and ACCs.
Key Benefits
No optical-side FEC means lower latency and lower module power than fully retimed alternatives. One family covers 500 m and 2 km, so DR8 and DR8-2 spares stay interchangeable in form factor and management. Breakout flexibility — the same 1.6T port can present as one 1.6TbE or two 800G-DR4 links. CMIS 5.0 management gives standard diagnostics on any modern switch line card.
Applications
1.6T leaf-spine links in AI/ML training clusters; 800G breakout from 1.6T switch ports to existing 800G NICs; cloud datacenter fabric upgrades; and multimode 2VR4 in-rack connections on 850 nm infrastructure.
