Multi-Mode Fiber vs. Single-Mode Fiber: Which Fiber Optic Cable Is Best for You?

As the world has become more connected, communications technology has grown on the back of fiber optics. With fiber optic networks becoming established worldwide, with thousands of miles of subsea cables connecting continents, it is no surprise that fiber sets the standard for transmission speeds and bandwidth. For home and business networks, consumers can access high-speed, reliable internet through fiber technology. However, to customize a network to your standards, you must consider the types of cables necessary for the job. Options include multi-mode fiber, single-mode fiber, and simplex and duplex cables.

Multi-Mode Fiber vs. Single-Mode Fiber

When installing fiber optic internet, you require various types of equipment, including cables. When choosing a line, your first choice is between multi-mode (MM) and single-mode (SM) fiber.

Multi-Mode Fiber

MM fiber transmits large amounts of data over short distances. While the distance capability has increased recently, it is still more beneficial for local network applications and data centers. MM cables have a larger core, which allows multiple light modes to pass through, increasing the amount of reflections. More data can travel across the cable, but unfortunately, it reduces the signal quality. MM is suitable for office businesses with only one building or with several locations within walking distance of one another.

Single-Mode Fiber

SM fiber has a small diameter that allows only one light mode to pass through simultaneously. With reduced attenuation, light can be transmitted over longer distances than the multi-mode fiber cable. Most cable TV and telecom companies use SM for long-distance signal transmission. Generally, SM cables are ideal for business parks or other institutions that require connections between buildings over a large area.

Simplex vs. Duplex Cables

Simplex and duplex cables have very different uses in various industries. One similarity, however, is that you can obtain SM or MM fiber in either simplex or duplex.

Simplex Cables

Simplex cables are also called single-strand cables because they have one fiber. On one end, you have a transmitter, and on the other end, you have a receiver. Simplex allows for one-way data transfer. For example, a trucking scale may need to send data to a central monitoring location but does not need to receive data back.

Duplex Cables

Originally, duplex cables had two fibers joined together, with one strand transmitting from point A to point B while the other from point B to A. Now, single-strand duplex fibers are more common, with a single strand sending data back and forth. Generally, duplex cables are necessary for telecommunications.

Fastening Buffer Cable vs. Loose Tube Cable

The major difference between fastening buffer cables and loose tube cables is the cables’ construction.

Fastening Buffer Cable

Fastening buffer cables are typically indoor multi-mode fiber cables. They are called fastening cables because of their tight buffer or cable jacket encapsulating the optical fibers. The buffer directly terminates the fiber without a junction box. Since fastening buffer cables do not have protection against expansion and contraction or extreme temperatures, they should remain inside.

Loose Tube Cable

Loose tube cables work well on long-distance applications when you need a high fiber count. As an outdoor cable, it can withstand harsh temperatures, and since it has no sheath, it can contract and expand easily.

Distribution vs. Breakout Cables

Breakout and distribution cables may seem similar at first glance. Both have uses within networking and telecommunications applications. 

Distribution Cable

Distribution cables connect multiple fiber networks in public locations. A distribution cable has its own 900-micron cable jacket and can bundle up to 144 fibers in the line. Generally, distribution cables are rigid and more difficult to work with because of their large size.

Breakout Cables

Breakout cables contain a single fiber, which makes them better for applications where the optical fibers connect directly to the equipment. The single fiber reduces the potential for signal loss and interference.

Determine Multi-Mode Fiber vs. Single-Mode Fiber Based on Your Needs

Fiber optic technology has led progress in communications technology for years. Different fiber optic cables have a variety of capabilities and uses. Whether your home or business requires multi-mode fiber or single-mode fiber, fiber optics is a worthwhile solution for your telecommunication needs.
