SUNNYVALE, Calif. -- Finisar Corporation (Nasdaq: FNSR), a technology leader in gigabit fiber optic solutions for high-speed data and telecommunication networks, announced today that it has made its first customer delivery of XFP 10Gb/s optical transceivers. These first XFP transceivers use a 1310nm DFB laser, and comply with 10km 10-Gigabit Ethernet (10GBASE-LR per IEEE 802.3ae) and SONET OC-192 SR-1. XFP transceivers feature a serial 10Gb/s electrical interface called XFI, which removes the need to place electrical mux/demux chips inside the module. This results in significant space, power and cost savings for datacom and telecom system manufacturers. The XFP is an application-agnostic ultra-small 10Gb/s optical transceiver module being standardized by the XFP MSA Group. Its small footprint and low power dissipation enables the highest board density applications in the industry. These factors, in addition to its protocol independence, provide the lowest overall system cost solution for OEMs. The Group currently has more than 65 member companies. Its founding members include Broadcom, Brocade, Emulex, Finisar, JDS Uniphase, Maxim Integrated Products, Ciena, ICS (a Sumitomo Electric company), Tyco Electronics and Velio. "We are extremely excited by the strong customer interest in XFP," said Rudy Hofmeister, Director of High-Speed Optics Development at Finisar. "This 10km XFP transceiver is just the first of an entire suite of XFP products supporting up to 80km links," he added. Finisar Corp.
