VI Systems offers 25G VCSEL-based TOSA and ROSA

At the OFC Exhibition next week, VI Systems will present a set of transmitter and receiver optical subassemblies (TOSA/ROSA) and the related building blocks for the next generation of 25 Gigabit Ethernet short-reach optical transceivers.

The components on display include the 25Gb/s TOSA with part number T25-850 and 25Gb/s ROSA with part number R25-850. VI Systems say these building blocks will enable a new generation of short-reach 25 Gigabit Ethernet optical receivers in a high-performance small form factor SFP28 package or for on-board assemblies.

The transmitter component features a built-in vertical-cavity surface-emitting laser (VCSEL) driver combined with a proprietary 850nm VCSEL chip. The receiver component incorporates a transimpedance amplifier chip combined with 700-890nm PIN photodetector chip.

The mechanical dimensions are 6 x 6 x 9mm (width x height x length). The power consumption of each component is specified with less than 90mW.

Visit VI Systems at OFC 2015 in booth 2637 in Los Angeles, California, from 24 to 26 March.
