Telecast Fiber Unveils the ‘CommLink’ Fiber Optic System

The TR6442i can carry two intercom channels over a single strand of fiber for more than 40 kilometers.

Telecast Fiber Systems, a producer of portable and fixed fiber optic systems for television broadcast production, debuts the TR6442i CommLink fiber optic transceiver system.

The CommLink is designed to carry two intercom channels over a single strand of fiber for more than 40 kilometers, according to the company. In addition, the CommLink will work with any type of A/V installation, such as professional events and industrial testing environments that require the ability to transport intercom signals over long distances.

“With the explosion in high-definition TV production, fiber has become indispensable for all types of productions because of its light weight and ability to transport high-quality signals without any degradation,” said Steve DeFrancesco, president and general manager of Telecast Fiber Systems.

Producers are now looking for fiber solutions that support equipment, such as cameras, microphones, and intercom systems, which are already in place in the operation, DeFrancesco said. “We designed the CommLink to fill the gap between the use of short-range copper cables and our high-end Adder II system,” he added. “Based on several years of research and feedback from SNG, OB, and studio operations around the world, the CommLink is ideal for any operation that requires the rapid deployment of communications systems over long distances,” he said.

The CommLink features the industry’s most advanced auto-nulling hybrid technology, making it easy to interface to industry-standard party line and matrix-style intercom systems, according to Telecast Fiber. When in two-wire mode, the CommLink will extend two channels of a Clear-Com party-line system or a RTS two-wire intercom system. When no intercom power supply is available, the CommLink transceiver can act as a power supply for up to five intercom belt packs, according to the company.

In four-wire mode, the system creates a fiber optic connection from a matrix frame to two remote matrix stations, using either Clear-Com Matrix Plus or RTS Advanced Digital Audio Matrix (ADAM), Cronus, or Zeus systems, the company says. All remote matrix stations are fully functional, with illuminated alphanumeric displays and call signaling.

Alternately, the CommLink system’s auto-nulling hybrid permits the easy interconnection of two-wire intercom to four-wire systems, providing an easy setup of a two-to-four-wire hybrid system, Telecast Fiber says. In addition, each end of the system can act as a stand-alone two-wire-to-four-wire interface, permitting connection of a four-wire intercom matrix to a two-wire intercom system or a series of stand-alone belt packs, the firm says.
