LOS ANGELES -- MEL announced today that the company plans to produce a low-energy consuming DWDM SFP transceiver (TRx), leveraging its patent-protected Chirped Fiber Bragg Grating and its athermal structure technology. The new tunable TRx, named as MLT (Mechanically Locked Tunable), excludes energy consumption for holding a tuned wavelength through mechanically locking the wavelength. As a result, the MLT SFP TRx consumes half of the existing EML-based transceivers and one third of the new tunable transceivers. Making this announcement, Dr. BW Kim, the CEO of MEL, stated that this product will be the world's first mechanically tuned SFP transceiver for telecom networks, providing green-energy conscious network operators with opportunity to save huge OPEX. He added, "Today's tunable transceivers are the products of lab engineers who had a fixation of changing wavelengths as many as possible, but in reality and practice, you need to seldom change wavelength while in operation for broadband data transport and access network."

The MLT SFP transceiver can be tuned to a desired wavelength via an electro-mechanic tuner by typing in a wavelength number on the panel of the tuner. Although the wavelength is mechanically locked for the end of transceiver life, if necessary, the wavelength can be re-tuned at different wavelengths repeatedly to support for any network performance or operational adjustment. Thus, with this dynamic and flexible wavelength provisioning functionality, the MLT SFP TRx will ease the cost of holding expensive inventory required with current fixed wavelength SFP products. The MLT SFP transceiver will support multi-data rate up to 10G, and it also represents powerful tuning range of 40 wavelengths with 100GHz spacing in C-band or L-band in a compact and low-power SFP platform.

"MEL is a leader in WDM-PON technology. The invention of the MLT SFP transceiver is the latest example of how MEL's focus on R&D has translated into innovative yet practical new products into the telecom marketplace," said Dr. Donald Yu, COO of MEL. MEL will be exhibiting the MLT SFP transceiver (TOSA only without the actual tuner) at the forthcoming ECOC show in Geneva, Switzerland, Sept. 19-21.
