Import 2x2b Optical Switch — Buy in wholesale FOB from Supplier in China

The 2x2B Optical Switch from Coreray Optical Communication Co., Ltd. is a mechanical fibre-optic switching device designed for routing optical signals between two input and two output ports. The unit measures 27 mm (L) x 12.6 mm (W) x 8.5 mm (H), with a tolerance of +/-0.2 mm, and weighs 16 g. It operates across wavelength ranges of 650-1310 nm and 1260-1670 nm, with testing wavelengths at 650/780/850/980/1064/1310 nm and 1310/1490/1550/1625/1650 nm respectively. Insertion loss is typically 0.5-0.6 dB, with maximum values of 0.8-1.0 dB depending on wavelength band.

The switch employs an epoxy-free optical path, eliminating contamination risks that degrade signal integrity in standard bonded assemblies. Latching and non-latching configurations are available, with a switching time of 8 ms or less and repeatability within +/-0.02 dB. Polarisation-dependent loss (PDL) is capped at 0.05 dB, while wavelength-dependent loss (WDL) and temperature-dependent loss (TDL) each remain at or below 0.25 dB. The device accepts 3.3 V or 5.0 V DC power and handles optical transmission power up to 500 mW. Standard operating and storage temperature spans -40 degrees C to +85 degrees C.

This switch suits optical signal switching and routing, network protection and restoration, network monitoring, video distribution, instrumentation resource sharing, and military communications. Buyers include telecom equipment manufacturers, data centre integrators, defence contractors, and test and measurement OEMs. The lifetime rating exceeds 10^7 cycles. All trade terms, certification status, and exact MOQ should be confirmed directly with Coreray Optical Communication Co., Ltd., as these are not stated in the source data.

Coreray Optical Communication Co., Ltd. is based at A-6F, 26th Keyuan Road, Nanning, Guangxi, 530007, China. The company holds a harbour trust tier on the platform, with a response rate of 0.00 percent and zero average response hours recorded. These signals suggest limited active engagement through the platform messaging system, so buyers should expect to initiate contact through alternative channels and verify responsiveness before relying on quoted lead times.

The listing provides detailed product parameters but does not state company history, workforce size, revenue, client roster, factory certifications, or ISO accreditation. The source description focuses entirely on the 2x2B Optical Switch technical performance, with no mention of R&D capabilities, patent portfolio, or vertical integration. Buyers evaluating this supplier should request audited quality management system certificates, reference deployments, and sample evaluation protocols directly from Coreray Optical Communication Co., Ltd.
