2CH 1310nm Optical Networking And Dense Wavelength Division Multiplexing DWDM

  This product is a 2CH 1310nm PM DWDM Module (2-channel 1310nm polarization-maintaining DWDM module), providing two 200G-spaced DWDM channels near 1310nm in the O-band, enabling dual-wavelength multiplexing/demultiplexing. The center wavelengths of the two channels are approximately 1309nm and 1310nm, with a passband of λc±0.2nm. It uses PM 1310 polarization-maintaining fiber, 0.9mm blue sheath, FC/APC connector, operates on slow axis, and features low insertion loss, high extinction ratio, high isolation, and high reliability. It is suitable for use as a small-channel-count DWDM front-end or module integration in 1310nm polarization-maintaining systems.

• Low Insertion Loss, Link Budget Friendly

    CH1 insertion loss ≤1.0 dB, CH2 ≤1.3 dB, passband ripple ＜0.5 dB, minimal impact on system OSNR and power margin, facilitating direct replacement/expansion in existing networks or experimental platforms.

• High Extinction Ratio, Excellent Polarization Performance

    Utilizing 1310nm polarization-maintaining fiber, the device extinction ratio ≥18 dB, combined with the FC/APC key alignment slow axis structure, stably maintains the polarization state in the polarization-maintaining system, reducing polarization-dependent noise and measurement drift.

• High Channel Isolation, Extremely Low Crosstalk

    Adjacent channel isolation ＞25 dB, non-adjacent ＞35 dB, return loss ≥45 dB, directivity ≥50 dB, effectively suppressing crosstalk between channels and ports, ensuring signal quality and system stability during dual-wavelength parallel transmission.

• Mature Structure, High Reliability

    Maximum optical power handling capacity: <300 mW; operating temperature: -5～+70 ℃; storage temperature: -40～+85 ℃. Standard 100×80×10 mm module package meets the requirements for long-term online operation and engineering projects.

• Easy Integration, Simple Selection

    Standard configuration includes 1.0±0.1 m, 0.9 mm blue-sheathed polarization-maintaining fiber and FC/APC connectors, providing a standardized interface. The fixed 2CH channel count and 200G channel spacing allow customers to quickly determine whether the system meets their project requirements based on whether two adjacent 1310nm wavelengths are needed and whether a polarization-maintaining system is required.
