optical transmitter

1310nm optical transmitter

Be important equipment to set up CATV HFC networks, and primarily used for TV video signal, digital TV signal, telephone voice signal and data(or compressed data) signal long-distance fiber transmission. The product use import high performance DFB laser transmitter as light source, RF drive adopts RF power digital automatic process technique and advanced RF pre-distortion circuit developed by our company and built-in perfect microprocessor automatic monitor system insure the excellent function of the product.

● Adopt word-famous company advanced DFB laser instrument; max output optical power reach 30mW.
● Add advanced RF pre-distortion circuit, to use as proofreading CATV system most important CTB and CSO index, and to improve C/N index.
● Adopt RF digital automatic control technology. It can automatically adjust drive level and make C/N, CTB, CSO index always in best state based on input RF level, number of channels.
● Adopt high performance Gallium Arsenide RF amplifier, let index higher.
● Built-in perfect power output automatic control circuit and laser thermoelectricity refrigeratory temperature automatic control circuit, insures highest output index and longest life.
● Built-in microprocessor automatic control circuit makes DFB laser always in best work state.
● Front panel blue VFD display, shows various main work status parameters and realizes automatic fault alarm and network management monitor.
● Field (I) model built-in big power thermostat may allow work environment difference in

1550nm optical transmitter

●Adopt several international patents pre-distortion dealing technology to guarantee the fine non-linear index.

●Adopt famous brand 1550 nm DFB laser instrument guarantee low noise, high power and high dependability.

●Can initiate the mode SBS function, offer more elastic disposition.

●Adopt Automatic Gain Control design, make different RF input level keep about equal output performance still, Simplify installing and operation sequence.

●The built-in microprocessor offers fine control performance and state to show that is controlled.

●RS485 controls the interface to control by carrying on the remote state.

●19”1U high-standard framework type installation.

Main board in this transmitter afforded by U.S. E-O Company and the transmitter passed assemble, test and aging by our company. It is comparative with foreign slap-up equipments at performance parameters and technology characteristic. Performance to price ratio is high and suitable for large or middle-size CATV fiber cable network.

Please Confirm When Order:

● SBS value (can design by our technique department, but you should afford engineering circuit drawing)

● 1550nm optical transmitter general requirement is 2 output at 7~9dBm, if you have no especial require.

● Output type is SC/APC , if you need to others, please tell us.

1550nm EDFA (Erbium-Doped Fiber Amplifier)

In order to reach high index and dependability, main instruments are all adopted imported famous brand to cooperate microprocessor automatic control circuit and high dependability switch power to assemble up. High dependability, low noise, especially double pump design makes noise index better. Each main technique performance index and technique plane can compare with foreign similar machine. And with high performance to price ratio, it is suitable for using at large or middle-size network.

● Imported erbium-doped fiber, and high steady imported 980nm pump laser or 980nm cooperating 1480nm pump (double pump structure), so noise is lower.
● Microprocessor automatic control circuit makes both pumps work at best state. Dependability and stability are better.
● Front panel blue VFD display, shows various main work status parameters.
● Various output power for selection.
● RS485 control interface can realize network management status monitor.
● 19" 1U high-standard framework type installation.
● With advanced circuit design, reasonable structure, slap-up material and high index, this machine is suitable for using at large or middle-size network.
