In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i. This makes it possible to scale capacity cost-effectively by using existing infrastructure more efficiently.

WDM systems are divided into three different wavelength patterns: normal (WDM), coarse (CWDM) and dense (DWDM).

A visual fault identifier or visual fault locator (VFI / VFL) is a visible red laser designed to inject visible light energy into a fiber. Sharp bends, breaks, faulty connectors and other faults will "leak" red light allowing technicians to visually spot the defects. Passive components consist of all the links and connections that unite communication devices on the overall network. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i. A WDM multiplexer, sometimes referred to as a mux, is the key to optimizing, or maximizing, the use of the fiber. The multiplexer lies at the heart of the operation, gathering all the data streams together to be transported simultaneously over a single fiber.

Optical fiber splitters can distribute optical signals to multiple target locations, achieving multiplexing of optical signals, saving the amount of optical fibers and cabling costs. Unlike active devices (which require power), splitters operate without electricity, relying solely on the physics of. It is a crucial component in Passive Optical Networks (PON) and Fiber to the Home (FTTH) deployments.
