2x4 1x4 Polarization Maintaining PLC Splitter , PM Fiber Splitter 1260nm 1650nm

  This product is a 2*(1*4) PM PLC Splitter (two sets of 1*4 polarization-maintaining PLC splitters), integrating two independent 1*4 polarization-maintaining splitter channels within a single module. It can evenly split two input beams into four output beams, making it ideal for centralized distribution and convergence in multi-channel polarization-maintaining systems. The device utilizes PLC planar waveguide technology and PM15-U25D panda polarization-maintaining fiber, offering a wide operating wavelength range of 1260–1650 nm. At a test wavelength of 1550 nm, it exhibits insertion loss ≤8.2 dB, channel uniformity ≤0.8 dB, extinction ratio ≥18 dB, and return loss ≥50 dB, combining broadband, polarization-maintaining, and high reliability.

• Dual-Group 1*4 Integration, Eight Outputs in One Module

    A single module simultaneously provides two groups of 1*4 PM splitters, enabling parallel distribution of two independent signals. Compared to multiple separate splitter solutions, this significantly reduces size and wiring complexity, facilitating standardized system design and installation.

• Low Insertion Loss and Excellent Channel Uniformity

    At 1550 nm, single-channel insertion loss is ≤8.2 dB, and inter-channel uniformity is ≤0.8 dB, effectively ensuring similar power at each output, providing a more easily calibrated optical power basis for multi-channel measurements, sensor arrays, or coherent systems.

• High Extinction Ratio, Strong Polarization Preservation Capability

    The device boasts an extinction ratio of ≥18 dB, utilizing PM15-U25D Panda polarization-maintaining fiber. The input FC/APC connector operates in slow-axis work, facilitating stable polarization in polarization-maintaining systems. The output, via an MPO/APC (male) interface, supports fast-axis work applications, enabling direct interfacing with downstream multi-core connector systems.

• High Return Loss and High Directivity, Reducing Reflection and Crosstalk

    With a return loss of ≥50 dB and a directivity of ≥50 dB, the device effectively suppresses end-face reflections and inter-port crosstalk, protecting the pre-stage laser, amplifier, and high-sensitivity detector while improving long-term system stability and signal-to-noise ratio.

• Wide Operating Wavelength and Environmental Adaptability

    Operating wavelength range 1260–1650 nm, covering multiple bands including O/E/S/C/L; operating temperature -5～+65 ℃, storage temperature -40～+85 ℃, maximum optical power handling 300 mW, suitable for long-term online operation in computer rooms, laboratories, and most engineering environments.
