QSFP+ optical transceivers for Ethernet apps

Tyco Electronics has launched highly compact 40Gbps QSFP+ optical transceivers, for use in switches, routers, data centres and other Ethernet applications.

The parallel-fibre optical modules have four independent optical transmit and receive channels for increased board density.

This extension to TE's QSFP product portfolio for the broad Ethernet and Infiniband standards marketplace combines the high-density and low-power benefits of parallel modules with some of the key advantages normally associated with SFP+-based modules, such as digital diagnostic monitoring for improved systems management.

They provide more than a 60 per cent increase in faceplate PCB density and simplify heat management through reduced power consumption (power dissipation of 0.8W) of more than 50 per cent compared with the use of four individual SFP+ modules.

Offering a digital diagnostic monitoring interface, the transceivers allow customers to easily manage and monitor key module parameters of a system through alarm and warning flags for module performance.

QSFP+ MSA- and SFF-8436-compatible, the transceivers are electrically hot-pluggable, allowing for port population on demand and in the field.

The latch mechanism eases insertion into board-mounted cages and optical connectivity is enabled via industry-standard MPO/MTP-terminated fibre ribbon.

The QSFP+ optical transceivers will be part of a live interoperability industry demonstration at the Ethernet Alliance booth at OFC/NFOEC 2011.
