2CH MFD PMFA Mode Field Diameter Matching Polarization-Maintaining Fiber Array

This product is a 2CH MFD PMFA mode field diameter matching polarization-maintaining fiber array, suitable for 1310/1550 nm band optical communication and photonic integrated coupling applications.

1. 2-Channel Mode Field Matching Design

   Utilizing a 2CH array structure with a core pitch of 250 μm, it is suitable for dual-channel optical signal coupling and miniaturized photonic device packaging.

2. Precise MFD Customization Capability

   Supports 6.0 μm, 7.5 μm, and 9.0 μm mode field diameters at 1310/1550 nm, and can also customize 3.3–10 μm mode field diameters. MFD tolerance is ±0.5 μm, typically ±0.3 μm.

3. Low Insertion Loss and High Return Loss

   Insertion loss ≤0.5 dB, typically 0.3 dB; return loss UPC ≥45 dB, APC ≥55 dB, contributing to improved link stability.

4. Stable Polarization Maintaining Performance

   Polarization extinction ratio PER ≥16 dB, typically ≥18 dB; supports slow-axis/fast-axis reference, axial angle selectable 0°, 45°, 90° or customized, axial alignment accuracy ≤±2°.

5. Highly Customizable Structure

   Materials include Pyrex, Tempax, Quartz, and Silicon, supporting lid/lidless structures and A-Type/V-Type angle designs; PM fiber options include UHNA1/UHNA3/UHNA4/UHNA7 and PM Panda fiber.
