SEPTEMBER 18, 2007 — Finisar Corporation (Sunnyvale, CA) will demonstrate interoperability between its chirp managed laser (CML) and optical duobinary (ODB) technologies at Booth 17048 during ECOC, September 17–19 in Berlin. The CML and ODB products result from Finisar's AZNA LLC and Kodeos Communications Inc. acquisitions earlier this year.
This is an emerging market area for Finisar, notes Rafik Ward, senior director of product marketing at Finisar. AZNA provided CML transmission technology; Kodeos the ODB products. Finisar will use the ECOC demonstrations to prove interoperability for secure 10-Gbit/sec. DWDM traffic, showing transmission over 200 km of single-mode fiber at the exhibition. These complementary products offer telecommunications system vendors an increased portfolio to meet performance, reliability, and cost requirements for metro, regional, and long-haul applications, Finisar claims.
The CML for extended reach transports 10-Gbit/sec. traffic over longer reaches without requiring dispersion compensation and is narrowly tunable, offering reduced supply-chain complexity as compared to fully tunable lasers, Finisar reports. It boasts a high output power of 4–7 dBm, low power consumption, and a small footprint in an industry-standard butterfly box format. CML is supplied as a cost-effective product for a range of applications.
Finisar's 300-pin MSA ODB transponders for extended reach at 10 G are broadly tunable in the C or L band and multi-rate (9.953 to 11.096 Gbit/sec.). With a built-in dispersion tolerance of ±3200 psec./nm and pin- or APD-based receiver configured with different decision threshold options, ODB transponders enable system vendors increase robustness and configurability of network architectures.
