The EXponder 10Gb Ethernet module operates at 1,310nm and complies with the XENPAK MSA for 10Gb Ethernet transceivers meeting the IEEE 802.3ae standard. The device is suited for use in edge and core switches and routers, hubs, and repeaters, as well as Ethernet switches.

"The MAN is generally considered to be the worst bottleneck for efficient end-to-end data transfer in the optical transmission network and the EXponder module is targeted at opening that bottleneck," said Erwin Wolf, VP of Infineon's Communications Business Group and GM of the Fiber Optics Business Unit.

The module provides a 10km LAN PHY link with full-duplex transmission, and uses serial 10Gbps uncooled and directly-modulated 1,310nm distributed-feed laser technology. This eliminates the need for modulators, coolers or complex optical multiplexing.

It also incorporates the PHY functionality from the optical interface to the XAUI and includes both 8/10B XGXS and 64/66B PCS coding and decoding. A data management interface is also provided for the data I/Os and clock.

The company claims the hot-swappable EXponder modules allows configurations of up to eight ports per line card without compromising the stringent thermal and EMI management requirements of 10Gbps optical electronics devices.

The EXponder is expected to be priced at <$1,000 in high-volume quantities.

The company also introduced the BIDI-TRX SFF single-fiber transceiver that allows two-way communication over a single optical network fiber. This eliminates the cost of the second fiber normally required for such communication while doubling the capacity of the network without adding any new fibers.

The module is ideally suited for use in PP networks, as a media converter in access applications, and for intra-office communication between switches, cross-connects, routers and servers.

The BIDI-TRX integrates receiver, transmitter, laser driver, power control, and automatic shutdown, into a PECL/LVPECL interfaced module. Full-duplex communication is enabled at data rates from 155Mbps to 2.5Gbps over distances of up to 20km and beyond.

The 155Mbps version of the BIDI-TRX is expected to be priced at <$100.
