Two new PurePath optical switches enable carriers to more cost-effectively manage the dynamic delivery of bandwidth in metropolitan and long-haul DWDM systems. The wavelength selective switch is based on liquid-crystal technology and, according to the company, is the first high-count, wavelength-selective optical switch that offers high isolation, low insertion loss, and a bidirectional design. The current model can switch up to 40 channels individually, each at 100 GHz, with uniformity of better than 1 dB across all channels. The switch is a reconfigurable optical add/drop module, capable of individually adding or dropping specific wavelengths, at 100 or 200 GHz, without any interruption of through traffic and can be designed for 2 to 12 wavelengths, depending on configuration requirements.

The MC2064 is a highly integrated, programmable FP/DFB laser driver intended for fiber-optic-based communications systems operating at up to 1.25 Gbits/sec. According to the company, it is the first to support DC coupled output at 3.3V operation and is available in TSSOP20, QSOP16 packages, or die form. This full-custom IC, fabricated in an advanced submicron BICMOS process, has a very wide operating operation, suitable for <100-Mbit/sec to 1.25-Gbit/sec applications. The outputs may be paralleled for 65-mA modulation. Both 3.3V and 5V operation are supported. Rise/fall times are substantially below the Gigabit Ethernet requirement of 250 psec.
The TeraChannel chipset's protocol-independent architecture offers scalability into the terabit range and provides 4x increased throughput in 1/4 of the real estate requirements. A 20-Gbit/sec TeraChannel fabric card requires only three fabric chips and can reside on a printed board measuring just 7x8 inches. First-generation TeraChannel technology provides up to 80 Gbits/sec of full duplex nonblocking user bandwidth and requires only six chips per fabric card. The compact nature is possible because of a very low-power, high-speed synchronous serial transceiver embedded within the chips, which enables high data throughput per fabric chip with low power consumption. Backplane size and routing complexity are reduced compared with lower-speed alternatives resulting in less space and more cost-effective designs.
