Description:
• The fiber-optic patch cord is a fiber-optic cable capped at either end with connectors that allow it to be rapidly and conveniently connected to CATV, an optical switch or other telecommunicationequipment. Its thick layer of protection is used to connect the optical transmitter, receiver, and the terminal box.
• The fiber optic patch cord is constructed from a core with a high refractive index, surrounded by a coating with a low refractive index, that is strengthened by aramid yarns and surrounded by a protective jacket. Transparency of the core permits transmission of optic signals with little loss over great distances. The coating's low refractive index reflects light back into the core, minimizing signal loss. The protective aramid yarns and outer jacket minimizes physical damage to the core and coating.
• The optical fiber patch cords are used in outdoor or indoor for connection to CATV, FTTH, FTTA, Fiber optic telecommunication networks, PON & GPON networks and fiber optic testing.

MTRJ connector:
• Acronym for Mechanical Transfer Registered Jack (MT-RJ);
• A Fiber optic Cable Connector popular with small form factor devices due to its small size;
• The connector houses two fibers and mates with locating pins on the plug.
• The MT-RJ uses an improved version of an industry standard RJ-45 type latch. This combination of a small form factor connector with the familiar RJ-45 latching mechanism ensures the MT-RJ connector to be the perfect choice for horizontal cabling needs to the desk-top.
Multiode dupex fiber optic cable:
• Multimode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multi-mode links can be used for data rates up to 100 Gbit/s.
• Multimode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion.
• The fiber optic cable, also known as an optical fiber cable, is an assembly similar to an electrical cable, but containing one or more optical fibers that are used to carry light.
• The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable is used.
