New 40/100Gbps Products

ignal conditioning in high speed optical networks requires monitoring and control of power, polarisation, noise filtering etc. Lightwaves 2020 has introduced five novel modules. High Speed Polarisation Controller This newly developed high speed polarisation controller has a response speed of a few microseconds. It is an endless polarisation controller designed for 40G/100G PMDC applications in combination with our novel polarimeter. It is a compact design at an affordable price. Mini Polarimeter A small form factor device that outputs four photocurrents that can be used to calculate both the state of polarisation (SOP) and the degree of polarisation (DOP). Covering 1525 to 1570nm, the polarimeter offers excellent optical performance, including low dark current, low insertion loss, low wavelength dependence, and wide dynamic optical power range. This device is ideal for integration into polarisation measuring and stabilising modules. High Speed VOA Its speed is measured in microseconds. This fast VOA is driven by voltage without any moving parts. It is ideal for high speed transmission application. An SFP module integrated with an optical power monitor is available. Wide Band VOA This wide band VOA offers a wide operating wavelength range from 1260nm to 1620nm. Compared to other VOAs (such as MEMS), it has better performance, such as lower ripple, smaller wavelength dependent loss across the whole range. High Speed Tunable Filter This high speed tunable filter is specially designed for 40G/100G ROADM applications as tunable add/drop or "coloured add/drop". It is ideal for scanning applications in test and measurement as well.
