Fibre-optic specialist, MultiDyne, is showing a new range of multiplexers and a new CWDM remapper/multiplexer that can transport up to 18 optical signals, including 4K, at NAB. Its HD-6Pack series of multiplexers is claimed to dramatically improve high-bandwidth signal transmission, and is capable of transporting up to 18 HD-SDI signals per fibre, including 4K. The CWDM multiplexers (HD-6000, HD-12000, or HD-18000) are claimed to offer broadcasters “an extremely powerful and economical HD-trunking solution.” “With today’s television viewers increasingly demanding data-hungry services — and 4K just on the horizon — fibre and bandwidth are both at a premium,” said Frank Jachetta, president of MultiDyne (pictured). “HD-6Pack multiplexers are designed to maximize efficiencies for users by supporting up to 18 HD-SDI signals on just one fibre. The high-performance platform has already been successfully tested by a large international broadcaster during a high-profile winter sporting event, demonstrating its reliability in the most severe weather and operating conditions.” Portable and easy to use, the HD-6Pack can easily support 4K applications, providing users with the capability to transport up to four 4K signals with one fibre. Designed for OB, fixed facility link, cross-campus network, and centralized control room applications, the system optimizes transmission anywhere signals need to be trunked — offering users a compact, cost-effective, multichannel solution for extending SDI transport. The HD-6Pack models are: a six-channel HD-6000, a 12-channel HD-12000, and an 18-channel HD-18000, which can, optionally, be rack mounted. An OLED display provides critical system information such as optical power levels, laser status, and bit rates, in plain language, providing users with total control over video transport. Any of the models can be configured for any combination of transmit and receive, for flexible, bidirectional transport. FS-18000 Fiber-Saver The new FS-18000 Fiber-Saver can also transport up to 18 optical or SDI signals over a single fibre, to simplify transmission in remote locations. It is “a significant advancement in the field of fibre-optic transport, as it can support up to 18 signals — including 4K — on a single fibre,” said Jachetta. “Reducing fibre count is extremely important to our customers. The FS-18000 Fiber-Saver answers their needs by enabling them to deliver high-quality signals cost-effectively from any location, regardless of fibre access.” The FS-18000 allows users to input any digital optical signal with a data rate of up to 4.25 Gbps. All 18 signals are seamlessly transmitted over one fibre, and then the receiver outputs each of the 18 signals individually. By receiving and retransmitting the optical signal, the FS-18000 Fiber-Saver offers a fresh optical budget to transmit signals over longer distances. It is available as a stand-alone device or can be rackmounted. Also new at NAB is MultiDyne’s 4K-4000 fibre-optic transport system. Designed to address the data requirements involved with delivering 4K digital television, it enables users to transport a 4K signal over one single-mode fibre. It is portable or rack-mountable, and there is also a card version for the openGear platform with SNMP management and redundant power. David Fox www.multidyne.com
