Insights Into Fiber Optic Adapter And Patch Cord

Networking is the backbone of any IT infrastructure. It's one of the most interesting concepts of technology, at least for network engineers. For many people working with networking devices is interesting as millions of people rely on them. Some of them even find working inside a data center with servers and networking components interesting.

Just think about the Google data centers where thousands of queries come every day and how strong their servers have to be to process those queries and revert the results to the users in a matter of minutes.

There are so many components, from small to large, included in those data centers and each one is important and interdependent.

So, in this article, we've discussed two basic devices of networking which are necessary for a fiber-based solution but people forget them easily.

Let's discuss why they are important and what's their use:

Fiber Optic Adapter:

It's a small device that connects the fiber optic patch cables to the switch. Their main function is to make sure that internet-enabled devices can communicate with each other. These adapters are the least evident yet vital devices that infrastructure managers tend to ignore it.

How do they work?

When working with optical fiber cables, you need to take care of the alignment of each fiber core. There are two components that help to get precise alignment, the ferrule within each connector and alignment sleeve within each adapter. Most of the connectors are based on the 2.5-millimeter ferrule. It plays a pivotal role in securing and aligning the fiber. Each of the fiber optic adapters is the alignment sleeve which brings together the ferrules of the two connectors.

Let's look at the different types of adapters and their specifics:

LC Standard:

They are useful for connecting the LC patch cables or LC connectors. You can connect LC to LC, LC to FC, LC to SC, LC to ST, and LC to MU, etc. These adapters come in various types including simplex, duplex, quad, single-mode, multimode, UPC, APC, PC with different types of sleeves.

FC Adapter:

This is useful for connecting FC patch cables or FC connectors. There are various types of adapters like square, single D, and double D, and come in single-mode and multi-mode versions. These adapters have ceramic sleeves and metal housing.

SC Adapter:

It is useful in connecting the SC patch cables and connectors and is available in various types like single-mode, multi-mode, zirconia sleeve, simplex, and duplex versions. Ordinary SC adapters come with plastic housing or metal housing. Most of the adapters come along with ceramic sleeves or bronze sleeves which are generally multimode.

ST Adapter:

This is useful in connecting ST patch cables or connectors and is available in simplex, duplex, single-mode, multimode, metal and plastic-type. The most common ones are in multimode.

Well, that was a whole lot of adapters. But there is one more equipment which is equally important but hardly noticed: Fiber Optic Patch Cables.

They are known as fiber jumper cables or fiber patch cords. They terminate with fiber optic connectors on both ends. It has two applications; computer workstation to the outlet or optical cross-connection distribution. You can use them for indoor application only and divide on the bases of different fiber cable mode, cable structure, connector types, connector polishing types, and cable sizes.

Let's look at the different types of fiber optic patch cables:

Single Mode Fiber:

This type of fiber is so small that only light rays at a zero-degree incident angle pass with less amount of loss. It has a core diameter of 8 to 10 μm. They use 9/125-micron bulk single-mode fiber cable and single-mode fiber optic connectors at both the ends.

Multimode Fiber Patch Cables:

Fibers having more than one mode are multimode fibers. There are two types: step-index multimode and graded multimode fiber. Step-index multimode fibers are useful in imaging and illumination whereas graded fibers are useful for data communication and network carrying signals to moderate distances, typically it can pass data for few kilometers.

10 gig Multimode Fiber Optic Cable:

It uses 50/125-micron fiber and optimized an 850nm Vertical Cavity Surface Emitting Lasers (VCSEL). It is backward compatible with existing network equipment and provides three times more bandwidth of traditional multimode fibers.

Final Word:

The fiber optic adapter and fiber optic patch cord are the most crucial and useful components of network designing. Hence, while designing the network make sure to choose the right kind according to your requirement.
