The AE20MRCAA uncooled XENPAK-compliant 10Gb Ethernet transceiver from Agere Systems is claimed to transmit up to 40km over optical fiberfour times the distance of standard uncooled devices.

Designed for use in MANs and long-haul market, the 1,310nm serial transceiver was developed using the same platforms as the company's 10km 10Gb Ethernet transceiver. The 40km device uses an uncooled laser and meets the reach typically achieved with 1,550nm cooled laser transmitters.

"With Agere's uncooled transceiver platform, customers using short-reach XENPAK transceivers can upgrade to longer distances without making a jump to more expensive technologies," said Mark Granahan, VP of Agere's Optical Access and Transport division.

The AE20MRCAA can send and receive data, optical-to-electrical and electrical-to-optical conversions, and deliver network management features such as an adaptable power supply and a programmable link alarm status.

It uses an integrated PHY IC to multiplex data in a 10Gb XAUI format (four 3.125Gbps electrical data lines) to one serial 10Gbps optical output on the transmit side, and make the reverse conversion on the receive side. The transceiver also features wide-open laser eye patterns that ensure high-quality transmission over the entire reach.

The AE20MRCAA is front-panel-pluggable and uses an industry-standard 70-pin electrical connector and SC duplex fiber optical connector. It consumes a maximum of 5.5W allowing improved system airflow and component reliability.
