Avago Technologies Introduces Four-Channel Parallel Optic Transceiver Module for High-Speed Router and Computer Interconnects

Avago Technologies today introduced a four-channel parallel optic transceiver module that operates at 3.125 Gbps per channel for an aggregate bandwidth of 12.5 Gbps and a link distance up to 350 meters. This distance and high-bandwidth capacity gives network designers the flexibility to create larger systems in central offices or large enterprises. In addition, Avago will demonstrate the industry’s first parallel optic modules to provide 5 Gbps transmission speed per channel, allowing an aggregate bandwidth of 60 Gbps.

Avago Technologies’ HFBR-7934Z parallel optic transceiver module is among the first in the industry to comply with RoHS 6 (Restriction of Hazardous Substances, EU Directive 2002/95/EC), and it features excellent EMI (electromagnetic interference) performance. The module helps network and telecom equipment manufacturers meet the growing demand for terabit data transfer in interconnects for high-end routers, server clusters (switch fabric interconnect) and other high-performance computing applications. It also solves the data capacity and space problems inherent with copper interconnects and existing optical transceivers.

“As the industry’s leading provider of high-quality parallel optic modules, our customers look to us to solve their information transfer bottlenecks with increasingly higher levels of bandwidth capacity and optical performance,” said Adam Carter, strategic marketing manager for the Fiber Optic Products Division at Avago Technologies. “This new transceiver module meets those needs, and it’s available in the high production volumes our customers require.”

The HFBR-7934Z parallel optic transceiver module is compliant with the POP4 (Pluggable Optics four-channel) multi-source agreement, and combines an 850 nm VCSEL with custom laser-driver integrated circuitry. The module provides four transmit channels and four receive channels in a single, space-efficient, pluggable transceiver package. Each channel operates up to 3.125 Gbps, compared with the 2.7 Gbps per channel bandwidth of previous POP4-compliant modules.

The HFBR-7934Z parallel optic module enables cost-effective, high-throughput interconnections between multiple chassis or racks of equipment in central offices or large enterprises. The modules can provide interconnects up to 150 meters on 500 MHz.km fiber, and 350 meters on 2000 MHz.km fiber. The transceiver receptacle uses the popular MTP/MPO ribbon fiber connector interface, and the electrical connection is made via the pluggable 10 x 10 Meg-Array connector system. Its integrated heat sink provides exceptional thermal dissipation.
