Import Both Axis Workinig Pm Circulator — Buy in Bulk from Supplier in China

The Both Axis working PM Circulator from Intepon is a polarization-maintaining optical device designed for bidirectional signal routing in fiber optic systems. It operates at center wavelengths of 1310nm or 1550nm, with insertion loss typically below 0.8dB and extinction ratio exceeding 20dB. The device supports single-mode fiber input and output, with ferrule alignment ensuring stable coupling. Its compact housing measures 40mm x 12mm x 10mm, optimized for dense integration in modules and rack-mounted systems.

This circulator uses PM fiber with a 125μm cladding diameter and a 9μm core, maintaining polarization states through stress-induced birefringence. The internal waveguide structure is fabricated using fused silica with precision alignment, a standard approach in telecom-grade circulators. The operating temperature range is -5°C to 70°C, and the storage range extends to -40°C to 85°C, consistent with industrial-grade optical components. No coating or encapsulation claims are made beyond standard hermetic sealing.

It is used in quantum communication setups, interferometric sensors, and high-speed coherent transceivers where polarization fidelity is critical. Buyers include R&D labs in photonics, manufacturers of optical test equipment, and system integrators in telecom infrastructure. Packaging is in anti-static ESD-safe tubes with foam inserts. Bulk orders are accepted, but lead time and packaging options require direct confirmation with the supplier.

Intepon is a supplier based in Shenzhen, China, with a registered address in Baicai Tech Industrial Park. The listing identifies it as an imported supplier with harbor trust tier, indicating verified export compliance and logistics capability. There is no public information on years in operation, workforce size, or production volume. The supplier does not claim ISO certification, in-house R&D, or OEM partnerships.

Response rate and average response time are not recorded in the listing, suggesting limited or no active engagement on the platform. The product is listed without price, MOQ, or lead time, and no client testimonials or project references are provided. This indicates a passive or catalog-only supplier profile focused on technical specification display rather than sales outreach.
