Optoplex Optical channel
monitor (OCM), also known as Optical performance
monitor (OPM), uses proprietary thin-film interference
filter technology combined with a micro-actuator and high-speed
electronics. Optical channel monitor / Optical
performance monitor is used to measure critical information
data on optical transmission signals in DWDM networks
for monitoring signal dynamics, determining system functionality,
identifying performance change, and providing feedback
for controling network elements so as to optimize operational
performance. In particular, Optoplex
Optical channel monitor / Optical performance
monitor can automatically scan the C-, L- and/or C+L-band
wavelength range and precisely measure channel wavelength,
power, and optical signal-to-noise ratio (OSNR) with a
60 dB dynamic range. See the following schematic diagram
for OPM working principle.
Operating through a continuous
wavelength scan and built-in wavelength reference with
optical tunable filter technology, Optoplex's Optical
channel monitor / Optical performance monitor
has a high wavelength accuracy and resolution with a low
channel cross-talk. Built with Optoplex's high-isolation
and wide passband thin-film filter and assembled together
with high-grade single detector, Optoplex's Optical
channel monitor / Optical performance monitor increases
channel power measurement accuracy and dynamic range.
Using an innovative optical design and high-grade single-element
InGaAs detector, channel OSNR measurement range is increased
to >30 dB. Further, the Optical channel monitor
/ Optical performance monitor includes a built-in
filter driver and PCB to control and interface with all
data-processing electronics. DPRAM, RS-232, or USB interfaces
are available and can be customized to meet specific requirements.
Optoplex's Optical channel monitor / Optical
performance monitor has passed Telcardia GR-468-CORE
tests. Moreover, the Optical channel monitor /
Optical performance monitor device features compact
size and low cost.
