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. |
