Product Description

10 dBm 1550nm Internally Modulated Optical Transmitter CATV secondary transmission networks
 

Products Descriptions
 

This transmitter is a high-index, multi-functional 1550nm internally modulated optical transmitter in top level. It adopts high linear DFB laser, with built-in pre-distortion compensation and AGC, APC, ATC control, which greatly improves the comprehensive index of the system.
HT1800S series 1550nm internally modulated optical transmitter is the core device for the construction of CATV secondary transmission networks. It is mainly used for value-added services such as TV image signal, digital TV signal, telephone signal and data (or compressed data) signal. It is a high-quality but low-cost solution to realize triple play and FTTx network transmission systems.

Features
 

* It adopts original low chirp and high linearity DFB laser as signal source.
* The perfect predistortion circuit ensures the perfect performance of CTB and CSO in high standard CNR value.
* Automatic gain (AGC) control enables stable output in different RF input level.
* Different networks can be optimized by OMI adjustment.
* Fully automatic case temperature control, intelligent fans, the fans starts to work when case temperature reaches 30 .
* Built -in dual backup power supply, hot plug and automatic switch supported.
* The working parameters of the whole machine are controlled by microprocessor and the LCD status display on the front panel has many functions such as laser status monitoring, parameter display, fault alarm, network management, etc.; once the working parameters of the laser deviate from the allowed range set by the software, the system will alarm promptly.
* Standard RJ45 interface provided, supporting remote network management of SNMP and WEB.

Preparation before installation
 

1 Please examine the machine to see if there is distinct
2 Please examine if the accessories is complete and the quality cards is here. If not, pls contact sales or dealer

Installation

1 Please keep a space about 4.5cm between machines for ventilation.
2 Please make sure: the socket works very well and well grounded; The impedance ≤4Ω; 220V power with three cablesthe middle one should connected to the groundIncorrect grounding may hurt the device or influence the quality of signal.
3 Please make sure the key is turned to OFF before the power supply connected.
4 Please keep the interface of the fiber clean before connecting the fiber. The connector could choose FC/APC or SC/APC.
