In radio and television and command center projects, the most likely cause of rework is not equipment failure, but mismatching of channel numbers and reverse direction. A reasonable approach is to work backwards from the outlets of the matrix and switcher, first make a complete list of signals, and then decide which optical transceivers to use.
The first step is to make a signal list instead of selecting equipment.
- Arranged by work location: How many video channels, how many audio channels, and whether reverse data and Ethernet transparent transmission are required.
- Marking direction: HDMI and SDI are mostly one-way. Microphone monitoring, PTZ control, and calls must confirm two-way.
- Standard distance and power supply: Copper cables longer than 100 m will be converted to optical fiber for evaluation. Whether the end can receive power is recorded in a separate column.
Select combined models according to business density
When the machine positions are densely packed, multi-channel composite models are preferred, for example4-way two-way HDMI+network+4-way independent two-way audio optical transceiver, one fiber core takes away four sets of pictures and independent audio, and the occupation of cabinet ports is significantly reduced. Suggestions for stand-alone or tourist flights1-way 3G-SDI audio and video optical transceiver, directly connected to the broadcast switcher, making link judgment easier.
From the large screen splicing controller to the screen wall, the picture has been cut according to the window. It is recommended to use the DVI non-compressor type to avoid edge jaggedness caused by secondary compression.
The number and identification determine whether it can be maintained later.
It is recommended to use a two-stage naming consisting of routing number and fiber core number. The local and opposite end labels must appear in pairs, and the patch panel account must be registered simultaneously.

By consolidating the list, model, and naming at once, the signal routing between the studio and the command center will have a replicable skeleton. Subsequent additions of camera positions are just a matter of adding rows to the table.
