Basics Closed Fiber Connector

Posted By fiberclosure top     October 25, 2018    


As everyone knows, Fiber Optic Splice Closure is utilized to join optical fibers where a connect or disconnect capability is required. A Fiber Optic Splice Closure has three major components: the ferrule, the connector body, and the coupling mechanism. Generally made from ceramic, metal, or high quality plastic, the ferrule is a thin structure (often cylindrical) that holds the glass fiber. The connector body is a plastic or metal structure that holds the ferrule and attaches to the jacket and strengthens members of the fiber cable itself. And the coupling mechanism is a part of the connector body that holds the connector in place when it gets attached to another device.

Since the fiber cable transmits pulses of light instead of electrical signals, it is important to choose a good Fiber Optic Splice Closure that aligns microscopic glass fibers perfectly in order to allow for communication. Nowadays, there are many different types of Fiber Optic Splice Closures in the market. Different kinds of optical fiber cables may need different connectors. And the Fiber Optic Splice Closures may be loosely classified into standard Fiber Optic Splice Closures, small form factor Fiber Optic Splice Closures, and ribbon fiber connectors. These family types of fiber connectors sometimes may overlap with each other.

Standard Fiber Optic Splice Closures: Generally having a ferrule of 2.5 mm, standard Fiber Optic Splice Closures are connectors commonly used in the fiber network. They can be both simplex and duplex and available in single mode and multi-mode fibers. ST, FC, SC, FDDI and ESCON are all standard fiber connectors. But they also differ from each other.

ST connector is the most popular connector for multi-mode fiber optic LAN applications. FC connector is specifically designed for telecommunication applications and provides non-optical disconnect performance. SC connector is widely used in single mode applications for its excellent performance. FDDI connector, which is a duplex multi-mode connector, utilizes two 2.5mm ferrules and is designed to used in FDDI network. And ESCON connectors are similar to FDDI connectors, but contain a retractable shroud instead of a fixed shroud.

Small Form Factor Fiber Optic Splice Closures: To meet the demand for devices that can fit into tight spaces and allow denser packing of connections, a number of small form factor Fiber Optic Splice Closures have been developed since the 1990s. In this type of small form factor Fiber Optic Splice Closures, some are miniaturized versions of older connectors, built around a 1.25mm ferrule rather than the 2.5mm ferrule.

Ribbon Fiber Connectors: MTP and MPO are compatible ribbon fiber connectors based on MT ferrules which allow quick and reliable connections for up to 12 fibers. Since the MTP product complies with the MPO standard, the MTP connector is an MPO connector. Along with the MTP patch cables, MTP connectors can upgrade the 10G network to 40G/100G.

In a word, the Fiber Optic Splice Closure is an essential part in fiber optical network. As the popularity of fiber optical network, about 100 Fiber Optic Splice Closures have been introduced to the market. So you can easily find the most suitable connectors for your special network.
