Fiber Optic Connectors and Adapters

Posted on by FS.COM

Fiber optic adapter or fiber optic coupler is a medium component, designed to connect two fiber optic cables together. A fiber-optic adapter allows fiber-optic cables to be attached to each other singly or in a large network, allowing many devices to communicate at once. Adapters come in versions to connect single fibers together (simplex), two fibers together (duplex), or sometimes four fibers together (quad). Optical adapters are widely uses in light distribution frame(ODF), the optical fiber communications equipment, the measuring appliance and so on.

Fiber Optic Adapter Specifications:
Insertion Loss Durability Operating Temperature: -40 to + 80°C;
Low insertion loss and back reflection loss;
High precision alignment;
Telcordia, ANSI, TIA/EIA, NTT and JIS compliance.

The fiber optic adapters are many types because of the diversity of the connectors. The fiber optic adapters are available in simplex, duplex and quad (for some types like LC and MU) configurations and with FC, SC, ST, LC, MT-RJ, MU, and more types, type MT-RJ is for use with fiber modem applications. According to the fiber connector types that the adapters used to connect there are standard fiber optic adapter and hybrid fiber optic adapter. Besides, there are also bare fiber optic adapter used to connect with the bare optical fibers directly.

Standard Fiber Optic Adapter
Standard fiber optic adapters are simplex, duplex and quad (for some types like LC and MU) structures, they are female to female type, used to link fiber optic connectors, typically they are with ceramic sleeves, fit for both single mode and multimode fiber optic connections.

Hybrid Fiber Optic Adapter
Fiber optic adapters are typically connecting cables with similiar connectors (SC to SC, LC to LC, etc.). Some adapters, called “hybrid”, accept different types of connectors (ST to SC, LC to SC, etc.). A hybrid connector can be designed to fit any two types of fiber-optic cables together. When the connectors have differing ferrule sizes (1.25mm to 2.5mm), as found in LC to SC adapters, the adapters are significantly more expensive because of a more complicated design/manufacturing process.

Fiber optic adapter are used in fiber optic connection, the typical use is to provide a cable to cable fiber connection. Connecting two cables together can allow two devices to communicate from a distance through a direct connection with the fiber-optic line. These simple types of adapters are often referred to as mating sleeves because they allow two cables to connect to one another. Some of these common line to line connectors are also built to connect three or four cables together.

Fiber optic connectors are available in many different models. Each model works with a specific type of fiber optic cable. This makes it even more important for the user to be sure of the type of fiber optic cable he/she is working with in order to make a compatible connection. Fiber optic cables must also be installed properly to ensure that fiber optic cores line up with each other and allow light to pass through them.

Fiberstore offers a wide selection of connector adapter, including FC, SC, ST, LC, MT-RJ, MU, simplex, E2000, FC/APC,duplex, SC/APC, LC/APC, E2000/APC ,quad, mating sleeves, hybrid fiber optic adapters, single mode fiber optic adapters and multimode fiber optic adapters.
