    LIGHTCONNECT Intros 100-GHz metro Dynamic Channel Equalizer

    Oct. 30, 2003
    30 October 2003 Newark, CA Lightwave -- LIGHTCONNECT today introduced a MEMS-based Dynamic Channel Equalizer (DCE) with 100-GHz ITU grid spacing and what the company claims is industry leading optical performance, including high extinction, low polarization dependent loss (PDL) and large useable bandwidth.

    30 October 2003 Newark, CA Lightwave -- LIGHTCONNECT, supplier of dynamic components and modules for optical networks, today introduced a MEMS-based Dynamic Channel Equalizer (DCE) with 100-GHz ITU grid spacing and what the company claims is industry leading optical performance, including high extinction, low polarization dependent loss (PDL) and large useable bandwidth. The 100-GHz DCE builds upon LIGHTCONNECT's 50-GHz DCE currently designed in at several major OEMs worldwide.

    "The overwhelming customer acceptance of our 50-GHz DCE in the long haul market validates the significant opex cost savings experienced by service providers when deploying fully reconfigurable OADMs [optical add/drop multiplexers," contends Yves LeMaitre president and chief executive officer of LIGHTCONNECT. "This new architecture is becoming the preferred solution in metro networks as evidenced by several recent RFPs. With the introduction of the new 100-GHz DCE, LIGHTCONNECT enables optical system manufacturers to offer ROADM solutions with best-in-class optical performance at the price of older static OADMs."

    The LIGHTCONNECT 100-GHz DCE can independently equalize or block up to fifty DWDM channels on a 100-GHz grid and is the ideal building block for designing cost-effective Metro ROADMs. These demanding applications require the most stringent optical performance, which the LIGHTCONNECT device is able to offer with an extinction of greater than 43 dB, useable bandwidth in excess of 55 GHz, and very low PDL, insertion loss, and in-band ripple, assert company representatives. The LIGHTCONNECT DCE is designed for reliability, ruggedness, and low cost manufacturing.

    The 100-GHz DCE communicates with the host system through either a Dual Port RAM or RS232 interface. For evaluation purposes, the DCE can be operated in automatic or manual mode with a user-friendly command set through a Graphical User Interface (GUI) running on a PC.

    The 100-GHz Dynamic Channel Equalizer is shipping now and is expected to U complete Telcordia qualification by first quarter of 2004. It is priced below $200 per channel in volume.
