Fiber Optic Cable & Accessories

Fiber optic cable is an advanced type of cable that uses glass fibers to transmit data as light pulses, offering several advantages over traditional copper cables. One of the primary types of fiber optic cables are single mode fiber and multimode fiber. Single mode fiber is designed for longer distances and has a smaller core that allows light to travel in one fiber, in a single path. Multimode fiber allows light signals to travel in multiple modes or pathways, which is suitable for shorter distances.
Fiber optic cables are incredibly efficient at data transmission, capable of handling higher bandwidth than copper cables. They are often used for high-performance data networking, fiber optic internet, and even in cable television services. These cables are immune to electromagnetic interference, a common issue with copper cables. Because fiber optic cables don't conduct electricity, they are safer for use in various environmental conditions and even have a higher level of fire resistance.
One key feature of fiber optic cables is their ability to support long-distance connections. While copper cables might require signal boosters to maintain signal strength over long runs, fiber optic cables are capable of transmitting data over longer distances without significant signal loss. This makes them ideal for applications like undersea cables and long distance network connections. The fibers used in these cables are often as thin as a strand of human hair but can transmit more data over a longer distance than their copper counterparts.

More Information about Fiber Optic Cables
In terms of assembly, fiber optic cables often come with color-coded connectors for easy identification. These cables are commonly used in complex installations requiring patch panels and fiber patch cables to connect multiple devices. Because of the optical nature of these cables, a light source like a laser light is used to generate the optical signal. The concept of total internal reflection ensures that the light generated within the cable stays within the glass fibers, facilitating effective data transmission.
Fiber optic cables offer faster download speeds, less signal loss, and the ability to transmit data over much longer distances compared to copper cables. They are a popular choice for both indoor and outdoor applications, particularly where high speed and long distance are crucial requirements.
FAQs
Can optical fiber cables be used for cable internet?
Yes, optical fiber cables can be used for cable internet, although the term "cable internet" is traditionally associated with broadband service delivered over coaxial cables. In modern network architectures, fiber optic cables are increasingly being used to deliver high-speed internet services, sometimes referred to as "fiber internet" or "fiber optic internet."
When does an optical fiber cable require a fiber patch cable?
A fiber patch cable, also known as a fiber optic patch cord, is commonly used to make connections between fiber optic equipment, such as switches, routers, and servers, and the main fiber optic cable network. The patch cable provides a convenient and flexible way to connect and disconnect devices without affecting the integrity of the main fiber optic line.
What cable types, besides fiber optics, carry signals for long distances?
Several types of cables are capable of carrying signals over long distances besides fiber optic cables. These include: coaxial cables, twisted pair cables, Ethernet over copper cable, T1/E1 lines, and Digital Subscriber Lines (DSLs).
Industrial Wire Types: Part 2
Twisted Pair Wire
Twisted pair wire is most commonly seen in scenarios where data is being transfer to and from certain locations. It uses two separate conductors, twisted together, for a single circuit. The two conductors are twisted together to reduce electromagnetic interference or “cross talk” between the two wires. It is common to use twisted pairs in place of a coax cable for data transfer. Coax can be fairly expensive and can be more difficult to run whereas twisted wire is not as thick or rigid and can easily be maneuvered in tough to reach locations. Twisted wire will always come in pairs, but there are no limits to how many pairs can be included in a single cable. For instance, CAT5 or CAT6 cable, which is commonly used in home and office networks, uses twisted pair wire. This type of cable has four different pairs of communication lines.
Shielded Wire
Shielded wire is different from regular wire insulation in that it is made of a conductive material. This conductive material includes, braided strands of copper (or other types of metal), non-braided aluminum and copper tape. The purpose of this shielding is to protect the signal passing through the wire from any outside interference. Unlike twisted cable, which is trying to eliminate interference among wire being used in the same circuit, shielded wire needs protection from outside interference and from other electrical circuits in the area.
Tray Cable
Tray Cable is a factory assembly of two or more insulated conductors, with or without associated bare or covered grounding conductors under a nonmetallic sheath, for installation in cable trays, in raceways, or where supported by a messenger wire. It is common to see tray cable that has many different conductors that can be used for control wiring, instrumentation and signal wiring as well as many other applications. Tray cable is often rated for use in direct sunlight applications, as well as direct burial applications. Because of the potential weight of tray cable when suspended, it will need to be supported properly to avoid hazardous environments.
