DECEMBER 7, 2006 -- Picolight Inc. (search for Picolight) has successfully demonstrated 1310-nm vertical-cavity surface-emitting laser (VCSEL) transceivers in a 10-Gbit Small Form Factor Pluggable (SFP+) design for the IEEE 802.3aq serial optical interface standard (search for 10GBASE-LRM).
With extended reach capability, small footprint, and low power consumption, the new transceivers satisfy a range of extended link applications on legacy multimode fiber applications up to 220 meters in enterprise networks, using electronic dispersion compensation (EDC), say company representatives.
Picolight recently conducted the demonstration as part of an Ethernet Alliance interoperability test at the Cisco Photonics Labs in Monza, Italy.
"The success of the product demonstration marks an important milestone in Picolight's continued industry leadership of VCSEL transceivers for extended reach applications," notes Vidya Sharma, vice president of marketing, Picolight. "With the recent adoption of the IEEE 10GBASE-LRM standard, Picolight is well-positioned to deliver a more cost-effective and power efficient solution for datacenters and enterprise networks as they look to extend their reach with 10G Ethernet applications."
Earlier this year, Picolight claimed to be the first company to demonstrate 10G 850- and 1310-nm VCSEL-based SFP+ transceivers at OFC/NFOEC 2006. Since the initial demonstrations in March 2006, Picolight has sampled 8/10G 850-nm SFP+ transceivers to more than 12 strategic customers and partners.
"Picolight was the first company to market 4G 1310-nm VCSEL-based transceivers for long-reach Fibre Channel applications, and this product demonstration further validates the performance benefits 1310-nm VCSEL delivers for the next-generation 10-Gigabit Ethernet deployments," explains Jack Jewell, founder and chief technology officer of Picolight. "Our 1310-nm VCSEL-based 10G Ethernet LRM SFP+ transceivers deliver lower power consumption at 450 mW, lower electromagnetic interference, and lower heat generation compared with distributed feedback lasers, resulting in increased performance and reliability of our 10G SFP+ transceivers," he says.
The 802.3aq serial optical interface standard was developed by the IEEE for the purpose of offering cost-effective and small form factor-compatible 10-Gigabit Ethernet optical links for extended reach applications on 62.5-micron Fiber Distributed Data Interface (FDDI)-grade legacy multimode fiber. 10GBASE-LRM uses EDC techniques to support transmission of 220 meters on installed legacy multimode fiber plant in data center and enterprise networks.
