VI Systems offers the T80-DRV-TB evaluation board with a new generation of single channel laser driver for non-return-to-zero (NRZ) modulation at bit data rates of up to 80 Gbit/s  “ON-OFF” keying (OOK) enabling low latency optical data transmission. The test board features two electrical 1.85 mm high-frequency connectors for differential signal input. The laser driver chip is also available as bare die chip for the assembly into transmitter optical assemblies. The driver chips are suitable for different types of directly modulated micro-lasers such as VCSELs or miniature DFB lasers having a high modulation bandwidth and can be applied for multi-mode and single mode data transmission.
