Product Description

High Performance Optical Parametric Amplifier with 1550nm 50km Internal Modulated Transmitter  for Long Distance Transmission

 

Products Descriptions
 

HT1800 1550nm directly modulated optical transmitter for long distance transmission adopts advanced electric dispersion compensation technology based on the standard model. The standard model will create serious chirp distortion (the bias current of the laser is modulated by the signal, and the optical frequency is shifted and jittered). The distortion becomes more and more serious with the increase of transmission distance, transmission bandwidth and the number of channels. This device adopts the advanced technology of EMD compensation. According to the actual transmission distance, it can accurately compensate in 1km step. The max compensation distance can reach 50km. It is mainly used in large area coverage and long-distance point-to-point transmission of secondary optical fiber network. It provides high-quality but low-cost solution to realize triple play and FTTx transmission system.

Features
 

1.The transmission distance is adjustable, max distance can reach 50km.

2.It adopts original low chirp and high linearity DFB laser as signal source.

3.The perfect pre-distortion circuit ensures perfect performance of CTB and CSO in high standard CNR value.

4.Automatic gain (AGC) control enables stable output in different RF input levels.

5.Different networks can be optimized by OMI adjustment.

6.Fully automatic case temperature control, intelligent fans, the fans starts to work when case temperature reaches 30 ºC .

7.Built -in dual standby power supply, hot plug in/out and automatic switching supported.

8.The operating 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 operating parameters of the laser deviate from the allowed range set by the software, the system will alarm promptly.

9. Standard RJ45 interface provided, supporting remote network management of SNMP and WEB.
