Description EFB Electronics Fiber Optic Cable Duplex ST Connector / SC Connector 62.5/125µ Multimode OM1 2.00 m ST Connector to SC Connector Duplex Connection Cable Color: Orange. Optical cables operate under the most challenging conditions, unlike copper cables. The optical fibers do not interfere with electronics. Additionally, the low attenuation of optical cables allows for long distances to be covered. SC connectors are standard connectors for fiber optic cabling. They feature automatic locking and twist protection. Their use is recommended for new installations of computer networks utilizing fiber optic technology. The connector is suitable for single-mode and multi-mode fibers. It can establish simplex, duplex, and multi-connections. ST connectors are connectors with a bayonet lock for fiber optic cables. They are suitable for both single-mode and multi-mode fibers. Technical specifications: Connection type: Fiber optic.
