Duplex Fiber Cable

Duplex fiber cable is a specialized optical fiber cable designed for bidirectional data transmission, consisting of two parallel optical fibers (one for transmitting signals and the other for receiving) encapsulated in a single jacket. This structure enables simultaneous two-way communication, eliminating the need for separate single-fiber cables for transmit and receive paths, thus optimizing wiring efficiency and reducing space occupation.

In terms of functional characteristics, duplex fiber cables typically adopt tight-buffered or loose-tube structures to ensure mechanical protection and stable signal transmission. They are compatible with both single-mode (SM) and multi-mode (MM) fibers: single-mode duplex cables offer low loss and long-distance transmission (up to tens of kilometers), ideal for high-speed backbone networks; multi-mode duplex cables support high bandwidth over short distances (hundreds of meters), suitable for indoor local area networks (LANs). Additionally, the cable jacket is often made of flame-retardant and wear-resistant materials, meeting indoor and outdoor environmental requirements.

Key application scenarios include data centers for server-to-switch connections, fiber-to-the-home (FTTH) projects for bidirectional broadband access, industrial automation systems for real-time device communication, and video surveillance networks requiring simultaneous image transmission and control signal feedback. It is also widely used in telecommunication networks and enterprise LANs, providing reliable bidirectional data transmission support for various high-speed communication systems.

Single-mode Duplex Zipcord Tight Buffer Indoor Fiber Optic Cable The duplex zipcord tight buffer cable is easily split into two single core cable, suitable for patch cord making. And this a kind of indoor cable, could be used in the interconnection of fiber optic equipment.

 

What Is Single-mode Duplex Zipcord Tight Buffer Riser Indoor Fiber Optic Cable 9/125 OS2
Single-mode Duplex Zipcord Tight Buffer Riser Indoor Fiber Optic Cable 9/125 OS2 This duplex cable consist of two child single core fiber. Each single fiber is coated with 250µm soft plastic, and then covered with a 900µm tight buffer thick layer of hard plastic, which add some fiber protection. The Kevlar yarn material ensure a good performance of tensile strength. And the Flame retardant outer jacket could be used in Riser environment. The cable diameter of each child single-fiber is 1.6mm, 2.0mm, 3.0mm optional.

• Soft,flexible and easy to do stripping, splicing and cabling
