Optical transceivers for 10 Gigabit/sec networks

Intel has introduced two new optical networking subsystems that lower the power consumption and increase the density of 10 Gigabit per second telecom networks.

Known as optical transceivers or transponders, the Intel TXN13200 family and Intel TXN17401 combine high-speed electronic components with a miniature optical receiver and transmitter in a subsystem that can be placed at each 10 Gigabit/sec port of an optical network.

With a footprint about the size of a credit card, the TXN13200 targets telecom applications where high port density is of importance. Applications include multi-port 10 Gigabit line cards in routers, switches and cross-connects in metro and core networks, and the client side of DWDM terminals in the enterprise. The Intel TXN13200 comes in two versions, one for OC192 SONET/SDH and one for 10 Gigabit Ethernet networks. The TXN13200 integrates the Intel LXT16784/85 Serializer/Deserializer and has a power consumption of 6.5W, nearly 35% less than previous generations of transceivers on the market.

The Intel TXN17401 supports 10 Gigabit Ethernet applications such as enterprise switches and routers and metropolitan area network equipment. This XENPAK MSA compliant subsystem features a 70-pin hot pluggable electrical interface and frontface pluggable optics that allow field installation and replacement of the optical module without replacing the whole line card.

Intel optical transceivers are produced through an automated fibre alignment process rather than the manual techniques used by other optical module manufacturers.

The TXN17401 will be priced below $1000 in high volume. Pricing for the TXN13200 will be less than $2000 in high volume. Samples of both products are currently available.
