Recently, EB-LINK cooperated with the integrator to complete the joint commissioning and delivery of the audio and video signal optical fiber transmission project of a city's radio and television studio. The signal routing between the studio area, control room and director room was changed to be carried by single-mode optical fiber, and long-distance copper cables were withdrawn from the first-line link.
Routes that cannot be supported by copper cables should give way first.
The straight-line distance from the studio area to the computer room exceeds 80 meters. The original high-definition copper link experienced edge flickering and occasional frame loss after working for a long time. The matrix panel was filled with thick and heavy copper cables, and maintenance of one line often required half a day of downtime. After the transformation, the same route uses optical fiber, and the link insertion loss is controlled at 0.5 dB. Only short jumpers are retained on the matrix side. Fault location has changed from measuring wires one by one to looking at indicator lights and unplugging jumpers.
Calculate the channel account first
- Camera positions and large-screen materials are grouped according to 2-channel HDMI plus two-way audio, select2-way HDMI+network+2-way independent two-way audio optical transceiver, one fiber core solves a set of signals.
- Director return, monitoring voice and PTZ control form separate links and do not compete with the main video for channel resources.
- Each route registers the fiber core number, wavelength and device numbers at both ends. These are written down once during handover, without relying on the master's memory.
Joint debugging and duty monitoring are arranged according to the program schedule
During the delivery phase, the test is avoided during the live broadcast period: the master and backup routing switching drills are conducted during the day, and all channels are lit up at once to confirm that there is no crosstalk, and then the board is closed and the lines are closed. The project followsAudio and video signal optical fiber transmission project in a city's radio and television studioAccording to the wiring and marking methods, serial numbers are registered one by one for arriving batches, and traceability can be traced later.
After fiber optic expansion, you only need to add channels and wavelengths, and there is no need to re-lay cables. It is especially cost-effective to renovate old studios.
