3G HD-SDI + Ethernet + DI/DO + Serial + Telephone + E1 Fiber Mux

View : 617
Type : Multi-Service Fiber Mux
Description :

The internal circuitry of the device adopts a fully digital design, ensuring reliable and stable operation, low power consumption, high integration, compact size, and easy installation and maintenance.


The device provides 8 ports 3Gbps HD-SDI video and 8 ports telephone interfaces. It also includes 8 ports digital input/output (or 4 ports RS232-422-485) interfaces. Additionally, it features 4 100Mbps Ethernet interfaces and 2 1Gbps Ethernet interfaces. The 3Gbps HD-SDI optical transceiver supports signal formats ranging from 270Mbps to 2.97Gbps, including SMPTE424M, SMPTE292, SMPTE344M, SMPTE259M, and DVB-ASI (270M) digital television formats.


Each Ethernet port has its independent bandwidth. The total bandwidth of the 6 Ethernet ports is 21000Mbps + 4100Mbps = 2400Mbps. The transmission is completely independent and physically isolated through a single fiber optic cable. The internal circuitry of the device adopts a fully digital design, ensuring reliable and stable operation, low power consumption, high integration, compact size, and easy installation and maintenance.




SD, HD, and 3G inputs are automatically detected, supporting rates from 270Mbit/s to 3Gbit/s. It also supports the new FULL HD 1080P/60HZ 3Gbps HD-SDI format signal, with a maximum transmission distance of up to 80 km. Supported signal formats include SMPTE 424M (2.97Gbps), SMPTE 292M (1.485Gbps), SMPTE 344M (540Mb/s), SMPTE 259M (360Mb/s), and DVB-ASI (270Mb/s).

The transmitter has automatic cable equalization: 80M for 2.97Gb/s, 140M for 1.485Gb/s, and 250M for 270Mb/s.

Both the transmitter and receiver have LED indicators to show the status of the SDI signal connection.

The 4 100Mbps Ethernet interfaces operate in full duplex mode, with each Ethernet port having its independent 100Mbps bandwidth and physical isolation.

The 2 1Gbps Ethernet interfaces support 10/100/1000M, full/half duplex auto-negotiation, with each group having its independent 1000Mbps bandwidth and physical isolation.

The 100Mbps Ethernet supports the transmission of VLAN jumbo frames and can be used with switch products that support the IEEE 802.1Q protocol. It can handle jumbo frames with a maximum length of 10240.

It supports 8 channels of voice input, with features such as caller ID display, reverse polarity billing, and fax functionality. The voice interface supports FXO/FXS/2-wire or 4-wire EM/2-wire audio/magnetic telephone interfaces. The FXO port interfaces with the PBX, while the FXS port connects to the user’s telephone.

It can connect to 8 digital input/output or 4 channels RS232/422/485 serial interfaces.

It has 1 Console management interface (optional) and 1 SNMP management interface (optional).

All interfaces are equipped with lightning protection that complies with IEC61000-4-5 (10/700μS) standards: Differential mode: 6KV with impedance of 40Ω; Common mode: 6KV with impedance of 40Ω.

Multiple power supply options are available: AC220V, DC-48V/DC24V, etc. It supports dual power modes such as AC+DC, AC+AC, and DC+DC.
