Custom Single Mode Fiber Optic Cables

When the signal has to go the distance, precision matters. MCC builds custom single mode fiber assemblies for long-distance, high-performance links.

Overview

Custom Single Mode Fiber Cables Built for Distance

Single mode fiber has a core about 9 microns in diameter, which limits light to a single path. With only one path, one signal won’t interfere with another. That lets single mode fiber send far more data over much greater distances than multimode fiber.

MCC builds custom single mode fiber assemblies in-house, from prototype to production, and tests 100% of the cables we manufacture before they ship.

Our single mode assemblies are built for:

Long-distance signal transmission

Telecom, datacom and broadcast links

Defense and aerospace applications

Harsh and tactical environments

Custom lengths, connectors and jackets

Built to spec. Tested before it ships.

Single Mode vs. Multimode Fiber

Both carry data as light. The difference is the size of the core, which decides how many paths the light can take and how far the signal can travel.

Specification	Single mode fiber	Multimode fiber
Core size	About 9 microns	50 or 62.5 microns
Light paths	One	Many
Wavelength	Longer wavelengths	Shorter wavelengths
Distance	Long distance, including intercontinental links	Shorter range
Typical uses	Long-distance networks, undersea cables	LANs, data centers
Glass types MCC builds with	Singlemode OS2	62.5 OM1, 50 OM2, OM3, OM4, OM5
Connection precision and cost	Tighter tolerances, higher complexity and cost	More expedient, less costly

Single Mode vs. Multimode Fiber Distance

Distance is usually the deciding factor. In multimode fiber, light follows several paths, which leads to greater signal dispersion over long distances. That makes multimode better suited to shorter runs such as LANs and data centers. Single mode fiber’s single light path and longer wavelengths keep signal degradation low, so it’s the choice for long-distance links. All undersea cables use single mode fiber.

Why Single Mode Demands Precision

Aligning two 9-micron cores takes tighter tolerances than multimode, which adds complexity and cost. If an application doesn’t need single mode performance, multimode is a more expedient, less costly option. When it does, precise termination is what makes the difference.

Single Mode Fiber FAQ

Answers to common engineering and ordering questions.

What is the difference between single mode and multimode fiber?

Single mode fiber has a core about 9 microns in diameter that limits light to a single path. Multimode fiber has a larger core, most often 50 or 62.5 microns, that lets light follow more than one path. Single mode is used for long distances; multimode for shorter runs such as LANs and data centers.

How far can single mode fiber run?

Single mode fiber is built for long-distance transmission, including intercontinental links. All undersea cables use single mode fiber. Distance in a specific application depends on the system.

Is multimode fiber less expensive than single mode?

Often, yes. Aligning 9-micron single mode cores requires tighter tolerances, which adds complexity and cost. If an application doesn’t need single mode performance, multimode is a more expedient, less costly option.

What connectors are available on single mode assemblies?

Options include MTP (male with pins or female without pins), UniBoot LC, LC, LC/APC, SC, SC/APC, ST, D4, MU, FC, FC/APC and MTRJ.

Can MCC build rugged single mode assemblies?

Yes. MCC combines connectors with defense-grade tactical cable built to withstand high tensile loads, severe crushing forces, repeated impacts and extreme temperatures.

Do you test single mode cables before they ship?

Yes. MCC tests 100% of the cables we manufacture and ship.
