March 10, 2016
VI Systems GmbH has unveiled a fiber-coupled 850-nm vertical cavity surface emitting laser (VCSEL) transmitter module for PAM-4 and PAM-8 test applications. The VM64-850M can support data rates of up to 80 Gbps, the company says.

VI Systems GmbH has unveiled a fiber-coupled 850-nm vertical cavity surface emitting laser (VCSEL) transmitter module for PAM-4 and PAM-8 test and measurement applications. The VM64-850M can support data rates of up to 80 Gbps, the company says.

The transmitter module features a V-connector for the electrical input signal. A 50/125-micron multimode fiber handles the optical output a 50/125 multi mode fiber; a standard FC/PC connector terminates the fiber.

The VM64-850M transmitter module has a footprint of 62.5x16.7 mm. The height of the module is specified as 8 mm. The fiber cable length is typically 1 m.

The maximum optical output power is specified at 4 mW. The typical operating voltage is 2.4 V.

VI Systems will present the module at OFC 2016 this month in Anaheim, CA.
