Fiber optic cables are also known as optical fiber cables. They are cables containing fiber strands inside an insulated casing which carry light over long distances and are designed for high-quality data networking and communications. The wires contained in thee cables are made up of two-layer of glass, which is the core that sends a light signal, and the cladding layer surrounds the core. There are two kinds of optical fiber cables, i.e., Single Mode Fibre (SMF) and MultiMode Fibre(MMF). The SMF has a narrow center and produces a single mode of light, while MMF has a broader core and multiple ways of light. With the world is moving from copper cable networks to fiber optics; thus, more people are looking to install them within their surroundings. You can check out more about MPO cable. In this writeup, we look at what to consider when selecting fiber optic cables.
Factors to consider when choosing fiber optic cables
- Decide the type
Know the type of cable you want, either single-mode or multimode. They are both not compatible; hence you need to be keen when selecting one. Single-mode have few varieties, while multi modes have a wide range to choose from; OM1, OM2, OM3. The kind of fiber optic depends on the hardware inside and the cords that can be attached.
- Fiber count
Different fiber optics use different bandwidths to run, and this depends on the fiber count. A higher fiber count results in high bandwidth. It is essential to select cables with a higher fiber count than required. Also, pull more fibers than you need before use.
- Type of jacket
The kind of jacket usually depends on the application. The most standard jacket is the Optical Fibre Non-conductive riser (OFNR). They come in standardized colors, but custom jackets are also available if needed. Multimode is orange, Singlemode is yellow while outdoor/indoor are black. Also, many styles are available for indoors, outdoors, or a combination of both.
- Internal construction
The build of the fiber optic is based on its purpose. Four ways of construction development are:
- Distribution or tight pack
All fibers are designed to be in a single jacket.
- Breakout or fan-out
All the buffered fibers are in individual jackets. They are used mainly in the device to device connections.
- Zipcord or assembly
The fibers appear singly or duplex in each jacket. They are mostly found in jumper cables.
- Loose tube
It has non buffered fibers that run in a semi-rigid tube with a gel inside that’s water repellent. The semi-rigid tube enables it to stretch without stretching the cords.
- Environmental construction
The environment plays a considerable role while choosing a fiber optic cable. There are different cables for different situations, outdoor, indoor and even aerial. Choose appropriately, then purchase.
- Fiber reel needed
The fiber is purchased for a specific work straight from the manufacturer. The length and number of reels used to depend on the job needed to be done. You must have background knowledge of what is being worked on beforehand.
Conclusion
You should think twice before purchasing fiber optic cables because they are a bit expensive but again consider the technologies you need. Acquire knowledge of what you want precisely and buy accordingly.
