VI Systems 850nm VCSEL chip tested up to 160 Gbit/s

14 Nov 2016 - VCSEL,equalization technology
BERLIN, Germany, Oct 05, 2016, Several test partners revealed at the ECOC 2016 in Duesseldrof, Germany record data transmission results using VI Systems fiber coupled 850nm VCSEL modules. The results have been obtained with the latest generation of vertical cavity surface emitting laser (VCSEL) fiber coupled modules (V50-850M and V100-850M) in combination with advanced modulation schemes and equalization technology.

A data rate of up to 108 Gbit/s over above 100 m with 850nm multimode VCSEL was demonstrated using pulsed amplitude modulation (PAM) with 4 or 8 levels (4-PAM and 8-PAM).
A discrete multitone modulation (DMT) was applied to single mode 850nm VCSEL for data transmission of 112 Gbit/s over 100 m of multimode fiber.
With duo binary 4-PAM modulation technology a maximum data rate of 160 Gbit/s (BTB) or 150 Gbit/s over 100 m of  multimode fiber using multimode VCSEL have been demonstrated.
