Product Description

1. General Description

This is a high-performance bi-directional parallel active optical cable assembly supporting 100-Gbps aggregate bandwidth, designed for InfiniBand EDR and 100G Ethernet 100GBASE‑SR4 applications. It uses 850‑nm VCSEL and PIN photodetector arrays over multimode fiber, offering longer reach, lighter weight, and improved signal integrity versus passive copper cables for simplified data center cabling.

2. Standard Compliance

• SFF‑8665 (QSFP28 MSA)

• SFF‑8636 (management interface)

• SFF‑8661 / SFF‑8679 (mechanical & pinout)

• IEC 60825‑1 (Class 1 laser eye safety)

• RoHS‑6 compliant

3. Key Features

• 4‑channel full‑duplex parallel transmission

• Up to 25.78 Gb/s per lane; 103.12 Gb/s aggregate

• Hot‑pluggable QSFP28 high‑density form factor

• Multimode fiber with 850‑nm VCSEL array

• Low power consumption: <3.5 W per end (retimed); <2.5 W per end (CDRs off)

• Round OFNP‑rated cable; LSZH available on request

• I²C‑based management interface (max 450 kHz)

• Commercial operating temperature: 0 °C to +70 °C

• Superior signal integrity and low BER
