Products/Services for dwdm picture
Wavelength division multiplexers (WDM) are passive devices that combine light signals with different wavelengths, coming from different fibers, onto a single fiber. They include dense wavelength division multiplexers (DWDM), devices that use optical (analog) multiplexing techniques to increase the carrying capacity of fiber networks beyond levels that can be accomplished via time division multiplexing (TDM).

Optical isolators are optical devices that allow light to be transmitted in only one direction. They are most often used to prevent any light from reflecting back down the fiber, as this light would enter the source and cause feedback problems. Search by Specification | Learn More about Optical Isolators
Fiber optic cables are composed of one or more transparent optical fibers enclosed in protective coverings and strength members. Fiber optic cables are used to transmit "light" data. Search by Specification | Learn More about Fiber Optic Cables
Electro-optic modulators are analog or digital devices that use an electric field to alter the characteristics (e.g., band gap and index of refraction) of a material through which light is traveling, changing the characteristics of the light itself. Search by Specification | Learn More about Electro-optic Modulators
Fiber optic transceivers include both a transmitter and a receiver in the same component. Search by Specification | Learn More about Fiber Optic Transceivers
Fiber optic switches route an optical signal without electro-optical and opto-electrical conversions. Search by Specification | Learn More about Fiber Optic Switches
Fiber optic test equipment is used to detect the signal loss/change through a fiber optic cable. Search by Specification | Learn More about Fiber Optic Test Equipment
Fiber optic transmitters are devices that include an LED or laser source, and signal conditioning electronics, to inject a signal into fiber. Search by Specification | Learn More about Fiber Optic Transmitters
Fiber optic attenuators are devices that reduce signal power in fiber optic links by inducing a fixed or variable loss. They are used to control the power level of optical signals at the outputs of light sources and electrical-to-optical (E/O) converters. They are also used to test the linearity and dynamic range of photo sensors and photo detectors. Search by Specification | Learn More about Fiber Optic Attenuators
