TE Connectivity's second generation of Paralight QSFP+ was designed with internally terminatedoptics and eliminates the need to clean an optical connector. The cables'passively cooled, environmentally-friendly design have a low thermal resistancepath from the chip to the connector shell. The Paralight QSFP+ active opticalcables have a lightweight design, diameter of 3.0 mm and tight bend radius.

This second generation of cables includesfour transmit and four receive channels at 10 Gbps per channel for InfiniBandstandard SDR, DDR and QDR applications. With 850 nm VCSEL technology, the cableassemblies operate over a data rate of 2.5 to 10 Gbps per lane with anaggregate data rate of 40 Gbps. The cables incorporate electrical-optical andoptical-electrical conversion that is built into the connector shell forimprovement in PCB real estate utilization.

The cable assemblies are available inlengths up to 100 m using 50 micron fiber, longer lengths are available uponrequest. The EOE circuitry is designed for use with 8B/10B encoded data streamssuch as InfiniBand, Fibre Channel and XAUI. The QSFP connector style supportsconnections for an I2C-serial interface, which can be used to identify theproduct and performance capabilities.

Product applications include high-speedinterconnects within and between switches and transport equipment,server-server clusters, super-computing interconnections, and rack-to-rack,shelf-to-shelf, board-to-board and board-to-optical backplane interconnections.The active optical cables meet the differential I/O per InifiniBand version1.2.1 specification.
