Tips To Choice Simplex And Duplex Fiber Cable

Sorting through cables and connectivity options can be a challenging exercise. Most times, Selecting the idea fiber optic cables for your set up depends on what effect you’re hoping to achieve. When purchasing a fiber optic cable, it is paramount  to have a knowledge  about distinctive  features  core  that are available within the cable itself. patch cords are used to connect to the patch panels and equipment. Therefore, choosing the appropriate connector type (LC/SC/ST/FC/MPO/MTP) is highly important. Usually, the both ends of the fiber optic patch cord are terminated with a  connector. You must be familiar will the patch cords before you can select the right one. One of the first things to determine when choosing fiber optic cables is the “mode” of fiber that you need. There’s really not much variety with single mode patch cords, but there is for multimode. Typically, Single-mode fiber patch cord uses 9/125um glass fiber, Multimode fiber patch cord uses 50/125um or 62.5/125um glass fiber. Single-mode fiber optic patch cord are best suitable  in long distance data transmission while multimode fiber optic patch cord is use in short distance transmission. Additionally, Pre-term fiber can be used in a variety of installation environments, and as a result, may require different jacket materials there are three cable jacket types: Polyvinyl Chloride (PVC), Low Smoke Zero Halogen (LSZH) and Optical Fiber Nonconductive Plenum (OFNP). Single mode and multimode  are usually used to accomplish connectivity between two BiDi transceivers, which is usually designed with LC simplex single mode fiber to fit the optical interface of the BiDi SFP/ SFP+ optics and operating wavelength. In addition, simplex BiDi WDM Mux/DeMux is designed for use in single strand fiber transmission. There are so many other components associated with simplex fiber solution, such as simplex PLC (Planar Lightwave Circuit) splitters, OADM (Optical Add Drop Multiplexer) and other simplex fiber products. As for duplex fiber optic cables, they are usually used in standard optical transceivers, such as SFP, 10G SFP+, 40G QSFP+ and 100G QSFP 28 (only LC duplex fiber cables can be used for long distance, such as 40G-LR4 and 100G-LR4). When the distance between two device is too long, duplex fiber is also used for inter-connector or cross connector between fiber optic transceivers and MPO/MTP cassettes.
Simplex VS. Duplex Fiber Optic Cables
Simplex and duplex fiber patch cords are composed of numerous   features and applications. However, With different connectors or cable constructions, there can also be different categories of optic patch cords. Simplex and duplex transmission define the methods of optical transmission, The word “simplex” suggests this type of cable allows data to travel in only one direction within an interface its made up of  one fiber and one connector on each end. Generally, Simplex cables are less expensive to build , allows for more incoming data at higher speeds. The protective jacket enables the cable to be connected and crimped to a mechanical connector.However, duplex fiber optic patch cord can be regarded as two simplex cables its composed of  two fibers and two connectors on each end. The duplex cable format allows for a dialogue, as opposed to the monologue provided by the simplex. However,  Being different from simplex fiber optic cable, this cable operates in a bi-directional movement  when it transmits data. Duplex patch cords are the most common type, because the way that most fiber electronics work is that they need two fibers to communicate
NOTE:
  • some duplex fiber optic jumper cables are with clips on the two fiber optic connectors at each side of the cable to combine the two connectors together.
  • The ends of fiber patch are connected with connector plugs for connection of light circuit activity.
  • These fiber patch cables can be with custom length. If you want to choose an optic patch cord, you need to take all these things into consideration, simplex or duplex, single mode or multi-mode, connectors, etc.
  • These are used most in FTTx/ telecom applications where signals are sent and received over one single fiber.
