Import 2×2 Optical Switch — Buy in Bulk from Supplier in China

The QH-OSW-2×2 is a fibre optic switching module from Qian Hua Electronic Technology Co., manufactured in Guangxi, China. It provides 2 input and 2 output fibre ports, enabling signal routing between optical paths with minimal loss. The unit measures 28.0 mm long by 28.0 mm wide by 10.0 mm high, a compact footprint suited to rack and panel integration in telecom and data centre environments.

Industrial-grade housing protects the internal optical elements, which are designed for repeatable switching over a high cycle count. Typical 2×2 optical switches in this class use single-mode fibre with SC, LC or FC connectors and operate across the C-band (1530 to 1565 nm). Insertion loss for well-built units of this size commonly falls between 0.6 dB and 1.0 dB, with crosstalk isolation of 50 dB or better, though the exact figures for this model should be confirmed with the supplier before order.

Network operators, fibre optic test labs and data centre integrators source 2×2 switches for optical cross-connects, protection switching and automated test setups. Qian Hua Electronic Technology Co. lists flexible MOQ arrangements and can quote on FOB or CIF terms; specific lead times, unit pricing and available connector types need to be confirmed directly with the supplier, as the listing does not state these details.

Qian Hua Electronic Technology Co. is based in Nanning, Guangxi, China. The supplier is listed at a harbour trust tier on the platform, which indicates basic verification has been completed, though the listing shows a 0% response rate and no recorded average response time. Buyers should factor this into their communication expectations and may wish to allow extra time for initial enquiries.

The company profile does not disclose its founding year, employee count, production capacity or specific client base. The listing covers optical switching components and references compliance with ISO standards, but does not name the specific certification number or issuing body. Independent verification of any claimed certifications is recommended before placing a bulk order.
