Leading-edge optical technologies for mission-critical services

KVH networks are continually upgraded with the newest technology to assure broadband service with world-class performance. Synchronous Optical Network (SONET) technology provides network redundancy with ring configuration, so in the event of connectivity difficulties, the path is switched within 50 milliseconds to prevent service disruption. Another key technology incorporated in our networks is Dense Wavelength Division Multiplexing (DWDM), which makes it possible to carry multiple wavelengths over a single optical fiber to significantly enhance transmission capacity.

Synchronous Optical Network (SONET) technology was first developed and utilized in the United States, and is the basis for the international synchronous digital hierarchy (SDH) standard. From the outset, SONET was designed to support ring networks, and is regarded as the ideal network technology to support reliable, secure telecommunications services. KVH uses a SONET-based ring network to provide telecommunications services of world-class quality. The double-ring structure ensures that if a fault develops on one circuit, the transmission path is substituted within 50 milliseconds to prevent an interruption to service
Dense wavelength division multiplexing (DWDM) is a fiber-optic transmission technology to combine multiple optical signals operating at different wavelengths into a single fiber. This technology allows the capacity of an optical fiber to increase dramatically.
Optical Fiber

Optical Fiber Cable
KVH utilizes the latest fiber technologies, which are capable of transmitting 300 times as much information as conventional telephone lines. Our 1,000-core cable is able to support advanced, high-speed, high-bandwidth telecommunications services. The silica glass from which optical fibers are made is highly durable and an abundant resource. Each fiber strand is about as thin as a human hair, and consists of a strengthened highly refractive core which ensures continuity of transmission.
