Polarization-Maintaining Outdoor Optical Cable
A polarization-maintaining outdoor optical cable engineered with 250μm PANDA-type polarization-maintaining optical fiber as the transmission medium, an aramid yarn layer as the stress-enhancing unit, and an extruded outer sheath as the outermost layer. This construction gives the cable excellent bending performance, high tensile strength, and long-term reliability for outdoor polarization-sensitive links.
As a factory-direct polarization-maintaining fiber optic cable manufacturer, we supply PANDA PM fiber cables and PM fiber jumpers for fiber-optic gyroscopes, coherent optical communication, sensing networks, and other applications where preserving the linear polarization state of light is mission-critical. Every cable is built to rigorous, scientifically sound manufacturing processes and can be fully customized to your project's optical and mechanical requirements.

Remark
- Specific technical and performance specifications of the product can be discussed and confirmed in detail based on the specific application requirements of the customer. Customized product development can be undertaken accordingly.
- The sheath material can be selected from options such as Low Smoke Zero Halogen (LSZH) flame-retardant material, thermoplastic polyurethane, and others, depending on the customer's application environment. The choice of sheath material will be confirmed based on the specific needs of the customer.
Why Choose Our PANDA PM Fiber Cable
Our polarization-maintaining outdoor optical cable is built around 250μm PANDA-type polarization-maintaining optical fiber (PM13G-125-U25), delivering excellent birefringence, low polarization crosstalk (<-25 dB/100m at 1310nm), and low attenuation (<1.0 dB/km). The aramid yarn strength member and extruded outer sheath give the cable a compact 3.0±0.2mm outdoor-ready jacket rated from -40°C to +70°C, while the fully dielectric build keeps the cable immune to electromagnetic interference — ideal for fiber-optic gyroscopes, interferometric sensors, coherent communication systems, and other polarization-sensitive deployments.
As an experienced PM fiber cable manufacturer, we support OEM/ODM projects with flexible sheath options (LSZH, TPU), custom lengths beyond the standard 2000-meter reel, and full technical documentation for every batch. Contact our engineering team to discuss your specification, connector termination, or bulk order requirements.
