When customers inquire about prices, they often confuse data optical transceivers and telephone optical transceivers. In fact, the signals transmitted by the two types of equipment are completely different. If you choose the wrong one, voice interruption or serial port packet loss will occur. Before selecting, clearly distinguish the business type.

Depends on whether the transmission is voice or data

The data optical transceiver transparently transmits RS485, RS232 or Ethernet, and the frame must be complete and cannot be truncated; the telephone optical transceiver uses PCM encoded voice, which pays attention to real-time performance and transparent transmission of on-hook and ring signaling. The two types of needs correspond toThree-in-one data optical transceiver and 8-way telephone + 1-way Internet phone optical transceiver, the interface and internal processing methods are different. To put it simply, one is like moving files and the other is like making a phone call, the sensitivity points to bandwidth and delay are completely different, and the problem of using the wrong model will appear in another form.

The trade-off between bandwidth and number of channels

• One-way voice is about 64kbit/s, and the 8-way plus one-way network can be multiplexed in one optical fiber.
• Serial data bandwidth is low, but more sensitive to delay and frame integrity
• For mixed services, multi-interface models with network channels are preferred to reduce the number of devices.

Choose the model according to the scene

For voice dispatching and duty calls, telephone optical transceivers are preferred; for sensor collection, access control and meter reading, data optical transceivers are preferred; for stations that require both telephones and meter reading, you can pressCommunication transformation plan for electric power and new energy stationsThe idea is to separate the two types of services into a network without affecting each other, and also facilitate independent troubleshooting and expansion. If the access control and meter reading personnel answer the phone at the same time, be careful not to force the voice into the data channel, otherwise it will be interrupted when busy.

One sentence to remember: choose the telephone type for calling, choose the data type for signaling, and if you want both, choose the multi-service model; if you are unsure, just hand over the spot list to Wolflight Helper.
