Radiant Shines With Release of DL-227 Transceiver

Huntington Beach, Cal. — Today at SCTE’s Conference on Emerging Technologies, Radiant Communications announced the launch of the industry’s first truly universal fiber optic transceiver, the DL-227. This single unit enables auto negotiation of various transmission speeds including 10, 100 and 1000 mbps.

Radiant’s copper-to-fiber media converter transmits up to 1 gigabit of data per second, a speed previously achieved only by purchasing and installing additional hardware. Additional benefits include the fact that the DL-227 is space economical and plug and play ready for easy installation. The fiber port of Radiant’s newest transceiver operates in full duplex mode, so the transmission distance is only limited by the power of the optics.

The DL-227 transceiver meets IEEE standard 802.3z/ab requirements and is backwards compatible with previously released Radiant products. In addition, it has the ability to automatically configure MDI crossover and can detect and self-correct common wiring problems including pair swaps, skew and polarity issues. Options are available for one and two fiber operation.

“Radiant Communications has employed cutting edge engineering to develop the highest performing transceiver currently available in the broadband market. The DL-227 offers a cost effective solution for MSOs seeking a transceiver that is designed to support current and future applications,” stated Lou Nagorksy, Radiant’s national sales manager.
