2x 12G, Sync and Ethernet to Optical Interface
An LC "EXP" port enables the Chronos to operate as a scalable solution. High Band units can interconnect with Low Band units via their optical expansion ports, effectively doubling the transport capacity. This configuration allows up to four 12G-SDI video, four sync outs and and four Gigabit Ethernet streams to pass over a single fibre link - allowing control of four cameras. Additional optical signals can be accommodated as long as they operate on unused wavelengths.
Each Chronos unit features four BNC connectors for 2x SDI video, genlock and one or two RJ45 Ethernet ports. The standard optical port is a dual LC connector, ensuring compatibility with industry-standard fibre systems. Compact and robust, the Chronos is engineered for reliable performance in demanding environments.
Chronos is the ultimate solution for high-capacity, long-distance signal transport in modern broadcast and live production setups.
