Product Description
The Kramer 690R is an outstanding high - performance fiber optic receiver designed for SDI video signals up to 3G HD - SDI. The 690T transforms two 3G HD - SDI signals into single - mode fiber optic format, and the 690R receiver then converts them back to the original two SDI formats. It's compatible with the fiber optic matrix VS - 88FO. Key features include a maximum data rate of 3Gbps, two single - mode fiber optic inputs on LC connectors, and two SDI outputs on BNC connectors. It's HDTV compatible and supports multi - standard operation such as SDI (SMPTE 259M and SMPTE 344M), HD - SDI (SMPTE 292M), and 3G HD - SDI (SMPTE 424M). It complies with laser standards like IEC 60825 - 1 and FDA 21CFR1040, being Laser Class 1 for safety. With Kramer's Equalization & Re - Klocking Technology, it can rebuild the digital signal for longer - distance travel on coax cables (200m for HD - SDI and 100m for 3G HD - SDI), and has a system range of up to 10km (6.2mi). Technical specs: Dual single - mode fiber (9/125) over LC connectors for inputs, 2 SD/HD/3G HD - SDI on BNC connectors for outputs, supports up to 3Gbps bandwidth per input, up to 10km fiber optic extension for 3G - SDI, 200m input cable equalization for SDI and 100m for 3G - SDI, 5V DC, 350mA power consumption, operating temperature from 0 to +40C (32 to 104F), storage temperature from - 40 to +70C (- 40 to 158F), 10% - 90% non - condensing humidity, comes with a power supply, product dimensions of 6.22cm x 5.18cm x 2.44cm (2.45' x 2.04' x 0.96' ) W, D, H, and weighs approximately 0.1kg (0.2lbs).
Using the Kramer 690R is quite straightforward. First, connect the single - mode fiber optic cables to the LC connectors on the input side of the 690R. These cables should be carrying the 3G HD - SDI signals converted by the 690T. Then, connect your devices to the BNC connectors on the output side to receive the original SDI signals. When it comes to power, just plug in the included power supply, which runs on 5V DC, 350mA. As for temperature, make sure to use it in an environment where the temperature is between 0 to +40C (32 to 104F). For storage, keep it in a place with a temperature range of - 40 to +70C (- 40 to 158F). Also, the humidity should be between 10% to 90% and non - condensing. To maintain the 690R, regularly check the cable connections to ensure they are secure. If you notice any issues with the signal quality, try using the Kramer Equalization & Re - Klocking Technology to improve it. This technology helps the digital signal travel longer distances on coax cables. If you need to move the device, handle it gently as it is relatively lightweight, only about 0.1kg (0.2lbs).
