Differential Phase-Shift Keying Demodulator (DPSK)

Convert phase modulation into amplitude modulation. Also called Delay Line Interferometer (DLI). Products cover DPSK and DQPSK demodulators.
 
    90-Degree Optical Hybrid for Coherent Detection
The six-port 90-degree optical hybrid mixes the incoming signal with the four quadratural states associated with the reference signal in the complex-field space and delivers the four light signals to two pairs of balanced detectors.

 
    Tunable Optical Filter
2-port optical tunable filter modules dynamically select a channel for drop. Standard products support 50 GHz and 100 GHz channel spacing, featuring wide passband and high isolation.

 
    Reconfigurable Optical Add/Drop Multiplexer (ROADM)
3-port reconfigurable optical add/drop multiplexer (ROADM) dynamically selects a channel for drop and allows other channels to express. Currently, 100 GHz ROADM is standard.
 
    Optical Interleaver
Both symmetric and asymmetric interleavers are available, operating at 12.5-25GHz, 25-50GHz, 50-100GHz, 100-200GHz, or multistage. Packaging with and without dispersion compensator.

 
    Optical Channel / Performance Monitor (OCM / OPM)
Measure channel powers, wavelengths and OSNR at optical layer in DWDM communications networks.

 
    Portable Spectrometer Engine
Standalone portable spectrometer engines provide flexibility for system integration in embedded test & measurement instruments.

 
    OEM Optical Filters
Currently, Optoplex offers flat-top comb filter, tunable edge filter, etc. These custom-designed share the product platform with optical interleaver and optical tunable filter.
