Coherent Solutions and SmarTest Electronics have announced an exclusive partnership and supply agreement to develop integrated electro-optical test and measurement solutions for high volume 400G transceiver testing.The partnership gives Coherent Solutions exclusive access to SmarTest’s next-generation Bit Error Rate Testers (BERT) and Pulse Pattern Generators (PPG) which will initially be used in single-platform test systems for 400G transc...

The IQFROG can be used to measure the intensity and phase of optical pulses in both spectral and temporal domains, giving a complete pulse characterisation. It is based on the principle of frequency-resolved optical gating (spectrally resolved SHG autocorrelation) which allows sub-picosecond resolution since it is not limited by the response time of the detector.

At OFC 2017 in Los Angeles (March 21-23) Coherent Solutions and Teledyne LeCroy are featuring a single carrier 64QAM 56GBaud live demonstration. The partners’ 672Gbs optical communications test platform incorporates the highest-performance equipment available for generating, transmitting, receiving and analysing coherent optical signals.

Five new optical test modules and a smaller benchtop chassis to expand the MTP test platform have been announced by Coherent Solutions. The new MTP modules - LaserBlade-DFB, Multimode VOABlade, terminating p PowerBlade, o2eBlade and SLEDBlade - add even more functionality to the optical engineer’s toolbox while improving testing efficiency and reducing workspace clutter.

The testing capability of Coherent Solutions communications test product portfolio has been enhanced by the CoRx-Tester. The CoRx-Tester provides automated measurement of key coherent receiver performance parameters specified by OIF. CoRx-Tester hardware consists of Tuneable Lasers, Variable Optical Attenuator and Polarisation controller configured in the flexible MTP-1000 modular test platform.

A DC-coupled optical to electrical converter module, the 02e, features a bandwidth of 25GHz the highest on the market today, according to Coherent Solutions. The amplified output of o2e makes it a perfect match to real-time oscilloscopes. The versatile o2e has a multi-mode input that accepts both multi-mode and single-mode input fibres and a broad 830nm – 1600nm wavelength coverage makes it compatible with a wide range of applications.

Ultra-short pulses in the order of femtoseconds and picoseconds are finding their way into various industrial applications from micromachining to optical sensing and imaging. Due to their extremely short time duration, they cannot be characterised using electrical test and measurement tools. Frequency-Resolved Optical Gating (FROG) technique uses autocorrelation of the pulses itself to characterise its intensity and phase profile, giving you a co...

Bias control of an IQ-modulator is an essential part of the coherent optical communication system. The need for stable and accurate modulator bias control has become even more prominent with the next generation 400G systems employing 16QAM modulation formats due to its sensitivity to optimum bias control.

  At ECOC 2015, which is scheduled to take place from 27th September to 1st October in Valencia, Spain, Coherent Solutions will announce the launch of its 40GHz IQTransmitter, IQTX-40.
