Import 1550nm Polarization Maintaining(Pm) Isolator — Buy in Bulk from Supplier in China

This 1550nm polarization maintaining (PM) isolator from Ruik-Tech Communication Co., Ltd. is a passive fiber optic component designed to protect laser sources from back-reflections while preserving signal polarization. The device operates at a centre wavelength of 1550nm with a typical peak isolation of 40 dB and a minimum return loss of 50 dB. Insertion loss at 23°C is rated at a maximum of 1.5 dB for the base unit, with a typical extinction ratio of 22 dB. The isolator uses PM1550 fiber and is rated for a maximum continuous-wave optical power of 500 mW in its standard configuration.

The listing specifies power handling variants from 300 mW up to 20 W, covering both single-stage and dual-stage configurations across multiple wavelengths including 1064nm, 1310nm, 1480nm, and 1550nm. When fitted with a connector, insertion loss increases by 0.3 dB, return loss decreases by 5 dB, and extinction ratio drops by 2 dB, with the connector key aligned to the slow axis by default. The operating temperature range is -5°C to +70°C, with storage rated from -40°C to +85°C. The component tolerates a maximum tensile load of 5 N.

These isolators are commonly integrated into test instrumentations, fibre optic communication systems, fibre sensor assemblies, and research laboratory setups. Buyers in the telecommunications equipment, photonics research, and sensor manufacturing sectors source this type of component for OEM integration. Ruik-Tech Communication is based in Shenzhen, Guangdong, and the listing does not specify MOQ, pricing, or lead times, so buyers should request these details directly along with connector type, stage configuration, and power rating requirements before placing an order.
