Opnext displays CFP MSA-compliant optical transceiver at OFC/NFOEC

MARCH 25, 2009 -- Opnext touts its latest offering as the first 100GbE optical transceiver for 10-km transmission over standard SMF.

MARCH 25, 2009 Opnext Inc. (search Lightwave for Opnext), a provider of state-of-the-art laser technology, says it has achieved the first 100-Gbps Ethernet (100GbE) optical transceiver for 10-km transmission over standard singlemode fiber (SMF). The transceiver is compliant with the IEEE P802.3ba 100GBASE-LR4 standard and with the CFP multisource agreement (MSA). This MSA is the first industry standard to support next-generation high-speed interfaces including 100GbE transmission. The transceiver is being displayed at the Opnext booth, #902 during OFC/NFOEC 2009, March 24-26 in San Diego, CA.

Opnext's 100GbE optical transceiver utilizes an in-house 1,310-nm wavelength range 25-Gbps electroabsorption modulator with integrated distributed feedback (EA-DFB) laser TOSA and in-house PIN-PD ROSA. Both the TOSA and ROSA were developed in collaboration with the Central Research Laboratories of Hitachi Ltd.

The device's low power consumption was achieved by using a high-temperature-operation EA-DFB laser based on Opnext's and Hitachi's advanced technologies of using semiconductor material with a temperature-tolerant band-gap structure. In addition, Opnext says, the cost-effective structure and compact size was achieved with non-coaxial 25-Gbps connections between the TOSA, ROSA, and GearBox IC.

"The availability of the 100GbE 10-km client-side optical transceiver is key for wide spread 100GbE applications," says Kei Oki, president of Opnext Japan. "This successful demonstration exemplifies our relationship with Hitachi CRL and demonstrates Opnext's ability to drive technology within the industry."

The optical transceiver is hot pluggable and is the same length but double the width of the 10GbE industrial standard XENPAK. It has an SC duplex receptacle optical connector and a 148-pin electrical connector with CAUI 10x10-Gbps signals. The transceiver requires a single 3.3-V power supply. Samples will be available in mid-2009 and will be in generally available in mass production in mid-2010.
