Simplex and Duplex Fiber Optic Cable Overview

Posted on by FS.COM

Simplex and duplex are with various cable structure types; they have some from single mode and multi mode which are related to fiber optic glass types. From Fiberstore, we provide some bulk fiber optic cables types in our store such as simplex fiber optic cable and duplex fiber optic cable,we also have other types cables in it. Customers have the flexibility to choose a cable plant to best fit their needs.We are the professional fiber optic cables supplier, and provide high quality service for you.

Simplex Fiber Optic Cable

Simplex fiber optic cables will be used when a signal only needs to go in one direction. They are designed for production termination where consistency and uniformity are vital for fast and efficient operation.

Simplex fiber optic cable consists of a single fiber,tight-buffered (coated with a 900 micron buffer over the primary buffer coating) with Kevlar (aramid fiber) strength members and jacketed for indoor use, and is used mostly for patch cord and backplane applications. Analog to digital data readouts, interstate highway sensor relays, and automated speed and boundary sensors (for sports applications) are all great uses of Simplex fiber optic cable. This form of fiber cable can be cheaper than duplex cables, because less material is involved. Simplex fiber cable is a single fiber available in single mode, multimode, or polarization maintaining, and they can meet the strength and flexibility required for today’s fiber interconnect applications. We also supply Riser, Plenum rated constructions and LSZH jacket.

Duplex Fiber Optic Cable

Duplex fiber optic cables consist of two fibers joined by a thin connection between the two jackets. Either single mode or multimode, they are used in applications where data needs to be transferred bi-directionally. One fiber transmits data one direction; the other fiber transmits data in the opposite direction. Larger workstations, switches, servers, and major networking hardware tends to require duplex fiber optic cable.

Duplex fibers types
  • Half-duplex: data may only be transmitted in one direction at a time.
  • Full-duplex: data is transferred in two directions simultaneously.

Other duplex infomation: a duplex communication system is a point-to-point system composed of two connected parties or devices that can communicate with one another in both directions, simultaneously. Now, duplex systems are employed in many communications networks, either to allow for a communication “two-way street” between two connected parties or to provide a “reverse path” for the monitoring and remote adjustment of equipment in the field.
