Portable optical system enables high-quality digital talk

LightWave Magazine Website

FiberWork Optical Communications, a developer of fiber-optic devices, has introduced its FWL Digital Optical Talk System. According to the company, this durable, portable equipment was especially developed to enable voice communications among field technicians during the installation, testing, and maintenance of fiber-optic networks, over distances up to 200 km.

The system's differentials include local and remote connection to Public Switched Telephone and PBX networks, in order to provide conference calls among field operators and company offices, as well as external remote calling. The system's FWL210 component provides full duplex communications through a single fiber, replacing radio communication, walkie-talkies, and mobile telephony, which, according to the company, can suffer from RF interference and low QoS.

The component can be configured for laser or LED operation across singlemode or multimode optical fiber, at wavelengths of 850, 1310, and 1550 nm. The company says the component eliminates long-distance phone calls and mobile/satellite phone bills, and is especially suited for use in hazardous environments where explosion risk and high electromagnetic interference are factors.

The company will demonstrate the system at this year's OFC/NFOEC conference.
