8CH 200G O Band PM Dense Wavelength Division Multiplexer For PON CATV Broadband / Optical Network

  This product is an 8CH 200G Oband PM DWDM Module, providing multiplexing/demultiplexing functionality for 8 DWDM channels within the 1260–1380 nm O-band, with a channel spacing of 200G. Typical center wavelength coverage is 1295.56–1312.58 nm, with a passband width of λc±0.2 nm, suitable for 1.3 μm band broadband access, PON, CATV, and DWDM service integration. The module uses PM13-U25D polarization-maintaining fiber, 0.9 mm blue sheath, FC/APC connector, operates on slow axis, and features low insertion loss, high extinction ratio, high isolation, and high reliability, allowing for easy integration into various O-band polarization-maintaining systems.

• Low Insertion Loss, Ample Link Margin

    Single-channel insertion loss <2.5 dB, passband ripple <0.5 dB, effectively reducing the impact of devices on system power budget and OSNR, leaving more margin for medium-to-long-distance or multi-stage amplification applications.

• High Extinction Ratio, Excellent Polarization Characteristics

    Utilizing PM13-U25D panda-type polarization-maintaining fiber, the channel extinction ratio >18 dB, while connector key alignment with slow axis (Slow Axis Works) helps maintain a stable polarization state in the polarization-maintaining system, reducing polarization-related noise and measurement drift.

• High Channel Isolation, Extremely Low Crosstalk

    Adjacent channel isolation >28 dB, non-adjacent channel isolation >40 dB, return loss >45 dB, directivity >50 dB, effectively suppressing inter-channel and inter-port crosstalk, ensuring signal quality and system stability during multi-wavelength parallel transmission.

• Excellent Channel Consistency, Easy System Calibration

    Due to the design's emphasis on channel-to-channel uniformity, the insertion loss of each channel is relatively similar, facilitating unified system calibration and compensation, and reducing the complexity of later software compensation and maintenance.

• Strong Reliability and Environmental Adaptability

    Maximum optical power handling capacity is <300 mW, operating temperature is -5～+65 ℃, and storage temperature is -40～+85 ℃. Combined with reliable packaging and manufacturing processes, it can operate online for extended periods, meeting the needs of both carrier-grade and engineering-grade applications.

• Standard Compliance, Suitable for Integrators' Mass Production Applications

    The design targets Telcordia and RoHS requirements. With standard dimensions and interfaces, it is ideal for equipment manufacturers and system integrators for serial design and mass deployment.
