World’s first optical cross-point switch

Philips Electronics has introduced a 12.5 Gbps single-chip asynchronous optical cross-point switch that will bring protocols such as SONET and SDH to Metropolitan and Wide Area Networks.

Royal Philips Electronics has introduced the TZA2060 – a 12.5 Gbps single-chip asynchronous optical cross-point switch that will bring protocols such as 10 Gigabit Ethernet, SONET and SDH to Metropolitan and Wide Area Networks.

The new generation of optical cross-connect systems for which the TZA2060 is designed will replace older generations of digital cross-connects by enabling switching at native line rates up to 12.5 Gbps. Optical cross-connect systems are one of the fastest growing application domains in optical networking. The TZA2060’s power consumption and jitter characteristics also make it suitable for other applications such as backplane switching, storage area networks, high-speed test equipment and video switching.

The TZA2060 is a 20×20 asynchronous cross-point switch with unicast, multicast and broadcast switching capabilities. It’s internal design, which uses Philips’ QUBiC4’G’ transistors, maintains highly symmetrical rise and fall times and reduces jitter to less than 2 picoseconds per switch.

A low jitter level enables designers to cascade as many as three TZA2060 switches without the need to insert clock/data recovery and re-timing logic in between them. In complex systems such as Clos switches, the result is lower component count, PCB area, and equipment manufacturing costs.

The TZA2060 operates from a single 2.5V supply and consumes less than 4W, resulting in typical power dissipations of 16W per Terabit of aggregated bandwidth. The TZA2060 also allows therouting of much smaller amplitude signals, resulting in lower parasitic coupling within the system. All the TZA2060’s 12.5 Gbps serial data inputs and outputs are CML compatible.

Evaluation samples of the TZA2060 are available now. In volumes of 1k units, the TZA2060 is expected to sell for around US$ 1,950.
