SEI and Anritsu demo 40Gb/s serial 1310nm EML for high-bandwidth next-gen networks

Tokyo-based optical component and module maker Sumitomo Electric Industries Ltd (SEI) and Anritsu Company, the US subsidiary of Japanese communications test & measurement provider Anritsu Corp, is conducting a joint 40Gb/s technology demonstration in Anritsu’s booth at OFC/NFOEC 2010 showcasing Anritsu's MP1800 BERT signal quality analyzer and MP1821A/MP1822A external 56G mux/de-mux, as well as Sumitomo Electric’s 40G electro-absorption modulated lasers (EMLs) and 40G receiver.

The Sumitomo devices are compliant with the XLMD multi-source agreement (MSA), which defines the electrical and optical interface specifications for 40Gb/s pigtail optical devices supporting the emergence of the compact 40G transceiver module market for high-capacity networks and storage systems.

“It demonstrates the viability of extending the transmission distance of 40G serial transmission in a conventional single-mode environment, offering higher bandwidth per fiber,” says Masahiro Kobayashi, general manager of the Lightwave Devices division of SEI subsidiary Sumitomo Electric Device Innovations Inc (SEDI). “This demonstration paves the way for a rapid commercial development of 40G systems.”

SEI’s 40G EML suits 43Gb/s serial applications and will be capable of distances up to 40km with an integrated modulator driver IC. The 40G receiver is housed in an 8-pin package with PIN and TIA and supports 30GHz bandwidth.

Anritsu’s 40G test solution supports testing from 0.1Gb/s to 56Gb/s serial BERT with the 3.5Vp-p high-amplitude output and cross point adjustment. The solution provides what is claimed to be the fastest Tr/Tf and minimum intrinsic jitter. The flexible and expandable configuration of the MP1800 BERT allows users to customize the system to fit their specific applications. The solution not only supports the 56G serial BERT but also 100G applications, such as CFP testing (25.78G x 4) and DP-QPSK.
