CMOS Photonics-based 40G Optical Active Cable

Wed, 08/29/2007 - 7:08am
ec79pi904a-LLuxtera, Inc. introduced a 40 Gigabit optical active cable (OAC), Blazar, which is said to be the world’s first CMOS Photonics product. The cable combines the characteristics optical modules and copper cables to provide a high bandwidth interconnect. The target markets are high performance computing InfiniBand and 40G proprietary rack to rack interconnect applications. With support for quad data rate (QDR), Blazar’s 40G bandwidth and extended reach of up to 300m overcomes the speed and range barriers that have limited InfiniBand applications to small computer clusters. The product’s power consumption is 2.2W per cable-end, resulting in 0.05W per gigabit of data. This reduces the overall power consumption that datacenters require to power the network equipment, according to the company. By permanently attaching fiber cable to optical transceivers, and powering four transmitters with a single hermetically sealed laser, Blazar’s features include a preassembled plug and play solution to reduce installation and maintenance costs. The cable connects to a system via a QSFP MSA-compliant connector cage. The electrical interface is SFP+ compliant, which enables it to support data rates of one to 10.5 Gigabits per transport lane for a total throughput of up to 42 Gbps. The company will begin sampling Blazar in Q4 2007, with production quantities available in 2008.
