VI Systems debuts 56G NRZ VCSEL driver and TIA chips

VI Systems has launched its first-generation 56Gb/s laser driver and amplifier chips designed for non-return-to-zero (NRZ) modulation in latency-critical optical communication links. The chips are designed to comply with the recently completed common electrical interface CEI-56G specification from the Optical Internet Working Forum (OIF), which specifies 56Gb/s NRZ signalling for very-short and ultra-short reach optical interconnects.

VI Systems offers 50G photo-detector module for R&D test

Optical components developer VI Systems has launched an ultra-high speed fibre-coupled photodetector module designed for test set-ups when developing advanced short-reach optical interconnects.

The D50-1300M module will support data rates of up to 50Gb in non-return-to-zero (NRZ) modulation or pulsed amplitude modulation (PAM) formats. The photodetector operates over an input wavelength range from 840nm to 1550nm, making it compatible with a variety of different protocols and technologies.

VI Systems introduces 56G NRZ modulator driver chip

VI Systems, a German developer of high-speed optical components for datacom, has introduced the A50-300C90, an optical modulator driver IC that supports data rates of up to 56Gb/s with non-return-to zero (NRZ) modulation.

The target applications are silicon photonics and integrated optoelectronic devices for short- and medium-reach data transmission in data centres and high-performance computing. Serial data rates based on 56Gb/s are being developed to support emerging architectures using Common Electrical Standard (CEI-56G) interfaces, 64G Fibre Channel and proprietary products.

VI Systems unveils VCSEL driver chip for 54G NRZ

VI Systems, a specialist in ultra-high speed optical components for datacom networks, has introduced the A50-150C driver integrated circuit suitable for driving vertical-cavity surface-emitting lasers (VCSELs) at speeds of up to 54Gb/s in the non-return-to-zero (NRZ) modulation format.

The target applications are short-reach optical interconnects for data centre and high-performance computing applications. The chip could enable a future generation of optical interfaces based on directly modulated high-speed VCSELs using 50Gb/s signalling on each lane.

VI Systems offers 850nm VCSEL module for 50Gb/s

VI Systems has introduced the fiber-coupled 850nm vertical-cavity surface-emitting laser (VCSEL) transmitter module V50-850M for data rates of up to 50 Gb/s. The transmitter module features a V-connector for the electrical input signal and for the optical output a 50/125 multimode fibre which is terminated with a standard FC/PC connector.   


VI Systems has introduced the 2nd generation of its 12-channel parallel optical testboards for p[erformance of up to 300 Gbit per second. The VHXT6212A-840 transmitter test board offers high speed electrical input connectors for differential signal input for each channel and standard SMA connectors for the supply voltage.
