• Product description:    The BH-MSVE2 series multi-service optical transceivers adopt the optical fiber multiplexing technology to enable the transmission of video, 2-channel 100M line-speed Ethernet/Gigabit Ethernet, FXS/FXO, voice, RS485/RS232 data and switch quantity signals over the same optical fiber line. The BH-MSVE2 is widely applied in occasions where public security, armed police and other organizations need multi-service access and networking. With one device, it can meet the networking requirements of users and is the ideal choice for users.https://succlink.com/wp-content/uploads/2025/01/20170910144327_11047.jpg

Product Features
◆ Truly isolated channels, ensuring that the two Ethernet signals transmitted through the same optical fiber line are completely physically isolated.

◆ Dual 100Mb/s Ethernet lines provide line-speed transmission with a total bandwidth of 200Mb/s

The upgraded version offers 2 Gigabit network connections.

◆ Provide 8-channel video.

◆ Provide 2-way 485 data channels

◆ Provide two telephone lines

◆ Provide 1 channel of RS232 data

◆ Provide 16-channel audio.

◆ Provide 16-channel switch quantity inputs.The Ethernet port supports AUTO-MDIX.

◆ The fault transfer function for optical path interruption: When the optical path line fails, it does not send the LINK signal to the Ethernet interface. Transmit to the opposite device.

◆ Supports Ethernet and has the function of Ethernet auto-recovery, thus avoiding system crash.

◆ Support caller ID display

◆ Rich status indicator lights for work conditions, which can facilitate and accurately reflect the working status of device interfaces and links.

◆ Built-in high-reliability switching power supply with wide voltage range (100V – 260V AC) for power supply.
