NEC Corporation Announces Extended Reach XFP Transceiver Based on AZNA CML TOSA.
Optical transmitter modules are optical devices used in optical interfaces of equipment such as large-capacity optical communications systems and high-speed router switches. Since conventional electro-absorption modulator integrated lasers (EML) or Mach-Zehnder modulators used in long-distance transmission are limited to a distance of around 80 km there has been demand for longer-range capability.
In a joint effort the two companies have demonstrated a compact PLC based CML TOSA, which allows further miniaturization of AZNA's CML transmitters. The Chirp Managed Laser (CML) uses a standard DFB laser and a passive optical spectrum reshaper (OSR) filter to achieve extended reach. NEC has developed a PLC-based OSR which can replace the current bulk version of the OSR used in AZNA products. The PLC based CML reduces parts count and allows passive optical alignment, which allows mass production leading to a lower cost.
The XFP transceiver with a CML-TOSA is scheduled for display at OFC 2007 (Optical Fiber Communication Conference and Exhibition) being held in Anaheim, California from March 27, 2007. It will be exhibited at the NEC FiberOptech, Inc. booth (#1241).
