Active optical cable assemblies

12 June 2013 Interconnection

Molex is supplying QSFP+ low-power 56 Gbps ‘fourteen data rate’ active optical cable (AOC) which delivers a reliable solution for aggregated data rates up to 56 Gbps over reaches up to 4 km. It requires less than 1 W per cable and provides the flexibility of traditional optical modules by interfacing to systems via a standard MSA (multiple source agreement) QSFP connector.

Featuring four bidirectional optical data links per end, each operating at data rates from 1 to 14 Gbps, the cables are compatible with multiple protocols including InfiniBand FDR, 10 Gb Ethernet, SAS 2.0 and 3.0 (6 and 12 Gbps), Fibre Channel (8 and 10 Gbps).

A low bit error rate (BER) of 10e-18 provides increased data reliability and a robust link compared to standard transceivers with 10e-15 errors per link. The cables are also available in a low-loss pigtail version, which allows customers to install the single-mode fibre separately and connect to the pigtail version to avoid constant high-cost cable upgrades as bandwidth increases.

The AOC cables are available in lengths up to 4 km. The firmware is field flashable via an I²C bus so cables can be reflashed while in the host system.
