Product Description
The Kramer 690R 2 - Channel 3G HD - SDI Fiber Optic Receiver is a top - notch device. It efficiently converts two 3G HD - SDI signals to single - mode fiber optic, and then the receiver can convert them back to the original two SDI formats. It's compatible with the fiber optic matrix VS - 88FO. Key features include a max data rate of 3Gbps. It has 2 single - mode fiber optic inputs on LC connectors and 2 SDI outputs on BNC connectors. It's HDTV compatible and supports multi - standard operation like SDI (SMPTE 259M and SMPTE 344M), HD - SDI (SMPTE 292M), 3G HD - SDI (SMPTE 424M). The Kramer Equalization & re - Klocking™ Technology helps the digital signal travel longer distances on the coax cable, up to 200m for HD - SDI and 100m for 3G HD - SDI. The system range can reach up to 10km (6.2mi). With the compact Kramer TOOLS™, 4 units can be rack - mounted side - by - side in a 1U rack space using the optional RK - 4PT rack adapter. Technical specs show that it has dual single - mode fiber (9/125) over LC connectors as inputs, 2 SD/HD/3G HD - SDI on BNC connectors as outputs, supports up to 3Gbps bandwidth for each input, can extend fiber optic up to 10km for 3G - SDI, has input cable equalization of 200m for SDI and 100m for 3G - SDI, uses a 5V DC, 350mA power source, operates at 0° to +55°C (32° to 131°F), can be stored at - 45° to +72°C (- 49° to 162°F), has a humidity range of 10% to 90% RHL non - condensing, measures 6.2cm x 5.2cm x 2.4cm (2.4' x 2.0' x 0.9') W, D, H, weighs approximately 0.14kg (0.31lbs), comes with a power supply as an accessory, and has an RK - 4PT 19' rack adapter as an option.
Using the Kramer 690R is pretty straightforward. First, connect your 3G HD - SDI signals to the single - mode fiber optic inputs on the LC connectors. The device will convert these signals to single - mode fiber optic. Then, the receiver will convert them back to the original SDI formats and you can access these converted signals from the BNC - connected SDI outputs. When it comes to the power supply, make sure to use the provided 5V DC, 350mA power source. As for the temperature, keep the device in an environment where the operating temperature is between 0° and +55°C (32° to 131°F). For storage, the temperature should be between - 45° and +72°C (- 49° to 162°F). Also, maintain the humidity within 10% to 90% RHL non - condensing. To keep it in good shape, regularly check the connections to ensure they are secure. If you want to rack - mount multiple units, use the optional RK - 4PT 19' rack adapter. This will allow you to neatly place 4 units side - by - side in a 1U rack space.
