VI Systems offers 64 Gbit/s 4-PAM VCSEL test modules

VI Systems launched test devices for PAM (pulse amplitude modulation) optical data transmission over multimode fiber. The fiber coupled test modules is suitable for data transmission using a 4-PAM or an 8-PAM encoding scheme for data rates of more than 64 Gbit/s.

BERLIN, Germany, March 8, 2016

VI Systems GmbH introduces the fiber coupled 850nm vertical cavity surface emitting laser (VCSEL) transmitter module VM64-850M for data rates of up to 80 Gbit/s. The transmitter module features a V-connector for the electrical input signal and for the optical output a 50/125 multi mode fiber which is terminated with a standard FC/PC connector. The left picture below shows the module. The picture on the right shows an optical eye diagram at 32 Gbaud (64 Gbit/s) in a back-to-back test configuration as tested by partners at the Heinrich Hertz Institute in Berlin.

The VM64-850M transmitter module is designed for test setups aimed at development of advanced short reach optical interconnects. The module footprint size is 62.5 mm x 16.7 mm. The height of the module is specified as 8 mm. The fiber cable length is typically 1 meter.

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

VI Systems will present an update on the technology achievements at the OFC 2016 conference & exhibition from March 22-23, 2016 in Anaheim, CA, including the 2.2km NRZ transmission over multimode fiber at 54 Gb/s.  Details can be found at http://www.ofcconference.org/en-us/home/program-speakers/

Visit VI Systems at the Photonics West exhibition at booth # 3763.
