Import 1064nm 2w Optical Fiber Faraday Isolator — Buy in wholesale FOB from Supplier in China

This 1064nm 2W Faraday-based optical fiber isolator from Ruik-Tech Communication is designed for polarization-maintaining (PM) applications, allowing light to transmit from input to output while blocking the reverse path. At a centre wavelength of 1064nm with an operating range of ±5nm, the device achieves a typical peak isolation of 35dB and a minimum isolation of 28dB. Insertion loss varies with input power, measured at a maximum of 1.7dB at 23°C, rising to 3.0dB at the full 2W input, with a minimum return loss of 45dB at both input and output ports.

The isolator handles a maximum average optical power of 2W and a peak power of 10kW for nanosecond pulses, with a maximum tensile load of 5N. For PM fibre variants, the minimum extinction ratio is 20dB, while polarisation-insensitive (PI) versions show a polarisation-dependent loss of up to 0.2dB. Typical industry specifications for Faraday isolators in this class include operating temperature ranges of +10°C to +50°C and storage from 0°C to +60°C, with FC/APC or FC/PC connectors being standard termination options.

Buyers in fibre laser manufacturing, MOPA systems, and optical testing instrument sectors use these isolators to protect seed sources and amplifiers from back reflections. Ruik-Tech, based in Dongguan, China, supplies this component as part of its broader catalogue of high-power and PM fibre components. Trade terms, exact MOQ, and lead times are not listed on the product page, so buyers should request these directly from the supplier, along with connector type and fibre type specifications before placing an order.

Ruik-Tech Communication Co.,LTD. is located at Floor 4, Building A, Zhaohe Industrial Park, in the Eastern City District of Dongguan, China. The supplier is listed with a 'harbor' trust tier on the platform, though its current response rate is recorded at 0.00%, meaning no average response time is available. The company profile states it is a manufacturer and supplier of optical passive components, with its product range covering high-power fibre components up to 100W and polarisation-maintaining fibre components.

The company's listed product portfolio includes optical fibre isolators, free-space isolators, optical circulators, pump laser protectors, band-pass filters, pump combiners, cladding power strippers, mode field adapters, and various polarisation-maintaining components like in-line polarisers, Faraday isolators, fused WDMs, and fibre patchcords. The profile mentions ISO9001:2015 certification, but buyers should request a current copy of this certificate directly from the supplier to verify its validity. No information on the company's founding year, employee count, or client list is provided in the listing.
