Multi-rate solutions for networks

Intel has introduced a new optical networking subsystem designed to deliver 10 Gigabit Ethernet and OC-192 Sonet/SDH communications on a single line card.

At the European Conference on Optical Communications, Intel introduced a new optical networking subsystem designed to deliver 10 Gigabit Ethernet and OC-192 Sonet/SDH communications on a single line card.

Intel also announced what it claimed was the world’s first complete CMOS Physical Medium Dependent (PMD) chipset for 10 Gigabit per second (Gbps) applications.

The Intel solutions support two key data transport standards for high-speed networks – Sonet/SDH and 10 Gigabit. While Sonet/SDH is the primary optical data transport standard deployed today in the telecommunications industry, 10 Gigabit Ethernet is becoming a desirable option for metropolitan area networks because it offers similar bandwidth at significantly lower cost.

The Intel TXN13303 operates at 9.95, 10.3, and 10.7 Gbits/sec by incorporating three customized jitter filters. By operating at all three rates, the product supports OC-192 Sonet/SDH, 10 Gbit Ethernet and forward error correction (FEC)-enabled optical systems.

Intel TXN13303 combines a laser source and receiver module with the Intel LXT16784/85 Serializer/Deserializer in a 300-pin, MSA compliant package. The TXN13303 is currently sampling and will be in full production in the first quarter of 2002.

Intel also disclosed development of a new product family that integrates an OC-192 Sonet/SDH Framer and 10 Gigabit Ethernet Medium Access Controller (MAC) on a single device. The new Intel component family will offer variations to support OC-192c, Packet Over SONET, 10 Gigabit Ethernet, and General Framing Procedure (GFP).

The new MAC/Framer product is designed for simple integration with an Intel TXN13303 SerDes transceiver to produce a complete line card solution supporting multiple networking protocols. This solution is applicable in systems such as core switches and routers, multi-service provisioning platforms, and enterprise gateways.

Intel’s 10 Gbps CMOS PMD chipset provides a solution for optical-electronic interfaces in OC-192 Sonet and 10 Gbit Ethernet applications. The chipset consists of the Intel LXT17001 Laser Driver, Intel LXT14002 Transimpedance Amplifier and the Intel LXT13002 Limiting Amplifier.

All three components are designed in CMOS process technology to reduce total power consumption of the chipset to less than one watt. The 10 Gbps CMOS PMD chipset is currently sampling.
