630 nm Polarization Maintaining Fiber Optic Connector/Patch Cord

These polarization-maintaining fiber optic patch cords feature high-quality, narrow-key ceramic FC/AFC connectors on both ends. Produced by our equipment, each patch cord is individually tested at the test wavelength specified in the specification label, ensuring extinction ratio and low back reflection (return loss) for both the fiber and its connections. These patch cords are in stock, featuring high-quality polishing to guarantee a typical return loss exceeding 60 dB. The test data sheet provides the extinction ratio and insertion loss test results for each patch cord. Each patch cord comes with two protective caps covering the ends to prevent dust or other contaminants from settling on the ferrule end face. We also sell protective FC/PC end caps separately, including CAPF plastic fiber caps and CAPFM metal threaded fiber caps. If you cannot find a suitable product among our in-stock patch cords, Terahertzlabs also offers custom patch cords that can be shipped on the same day.

Product features：Slow Axis Alignment、 Polarization-maintaining fiber with a pair of FC/APC connectors、 Wavelength range of 400-2200 nm、 Narrow key (2 mm) and slow axis alignment、 Typical 60 dB return loss、 Ceramic ferrule, 8° angle (APC)、 Ø3mm outer protective sleeve、 Custom patch cords available

Application area：Fiber optic communication system、 Fiber optic access network、 Fiber optic data transmission、 Fiber optic CATV、 Local area network (LAN)、 Test equipment、 Fiber optic sensors
