product function:thefiber modemis rs422 to fiber converter which realizes transmission of thers422 signal on fiber. This product has solved the problem of contradiction between communication distance and communication rate of rs422 port. At the same time, it also has solved the problem of electromagnetic interference, earth link disturbance and thunder/lightning destruction, thus greatly enhancing reliability, security and privacy of data communication. It can be widely used in various kinds of situations such as industrial control, process control and transportation control, and especially suited in bank, electric power as well as departments and systems which have special request to the electromagnetic interference environment.

features:

• based on self copyright ic.
• serial date creates receive and send signal automatically.
• rs232/rs485/rs422 interface can be optional by dip switch.
• serial port supports 0-115.2kbps baud rate auto-negotiation.
• combination of pdh technology and digital lock loop clock technology.
• unique serial port for circuit protection, supporting hot-plugging.
• data transmission is stable and reliable with integrated light-receiving and transmitting module.
• complete surface paste and install craft, industrial grade design, and production-runs with piece-pasting machine.

overview:e1 fiber modem is to modulatee1 signal to single or multi-mode fiber. Suit for transmit additional management data channel in different fibers.the fiber for transmit data can be used to monitor and control local and remote devices, and no collision will occur.

features:

nbased on self-copyright ic, and software content is high.

nprovide 3 type loop functions: local (ana), loop to remote (dig), command loop (rem).

npbrs codetesting function, convenient for install and test devices.

nremote rate adjustment to remote device (in primary clock status) when local terminal is in primary clock status.

nac220v or dc-48v power built-in

nit can support snmp management in our chassis installation

product function:v.35 fiber modem extends v.35 interface service over fiber. A pair of v.35 fiber modems provides n*64k(n=1-32) v.35 network extension between remote and locations .the bd-op-v35 is designed to transmit/receive v.35 data over one string of fiber. The bd-op-v35 allows transmission over single-mode fiber with distances up to 120km. Led status indicators monitor the fiber and v.35 links. The model bd-op-v35 is available with either an ac or dc power supply and is supported by a wide range of applications and power supply environments.

features:

• have two row of led, one indicates local status, the other indicates remote status
• the v.35 rate is n*64k, n=1-32.
• have two clock way: v.35 master clock and v.35 slave clock
• have three loop-back mode: fiber interface loop-back (ana), v.35 interface loop-back(dig), command the remote modem v.35 interface loop-back (rem)
• remote adjustment of velocity for the remote device will be available when the local setting into the master clock and the remote set into slave clock
• e1 fiber modem matching v.35 fiber by pair, one g.703/v35 interface conversion can be save out.
• it has pbrs test function and could be used as a 2m error code device.
• v.35 interface support hot-plug and can be connected with other dce or dte device.

the converter features compactness, light weight, low power consumption and high reliability.

product briefbd-op-e3 is an interface converter for e3 electrical and optical interface conversion. It is designed for the pdh equipment coaxial interface and optical interface interconnect.complete loop-back facility supported for system diagnostic and commissioning. Compact casing and simple operation achieve the cost saving and investment protected.

description
the switch fiber modem provide 2channel switch and 1channel serial data(rs232/422/485) over fiber tansmission. The fiber modem also can provide only 4 one-way switch over fiber transmission.

the product solve the electromagnetic interference, ground loop interference and lightning damage problems, improve the reliability, security and confidentiality of the data communication. The switch fiber modem can be widely used in various industrial control, process control, and traffic control and other occasions, especially for banking, electricity and departments have special requirements for electromagnetic interference environment and systems.

features

based on the integrated circuit intellectual property rights;

the input switch normally open and close automatically, when the input state, switch output that is why state, convenient opening;

the switch quantity of other switch state stability in the boot state or fiber no access, no chaos motion state;

provide 1 way switch and rs485 data;

a switch interface lightning reaches iec61000-4-5(8/20s) differential mode: 6kv, impedance (2); common mode: 6kv, impedance (2) standard;

the optional ac 220v, dc -48v, dc +24v, dc power supply positive and negative pole points (this device supports only dc +5v supply).
