Detailed Product Description

CATV 1310 Optical Transmitter use in DFB butterfly 1310mn laser, low noise, dual IC, optical power 6db-14dbm. RF input:70-85db

1310 Optical Transmitter

OFS-T2100E is a high performance forward path transmitter.19 inches rack mount structure, high linearity and low noise 1310mm DFB laser and state of the RF control circuits, pre-distortion, these make OFS-T2100E a desirable choice for metro HFC network.

OFS-T2100E uses 1310nm DFB laser with high linearity and low noise. Pre-distortion circuit improves the performance and stability of DFB laser. AGC/ATC mechanism provides protection to laser and ensures the performance and stability module and feedback to intelligent system platform. This ensures the laser to work at normal status and high performance.

Features

■ 1310 optical transmitter

■ Selectable AGC (automatic gain control) or MGC (manual gain control)

■ Accepts low signal input levels

■ Front panel LCD display

■ Low RIN, High CNR

■ High CSO, CTB and XMOD

■ High linearity and low noise DFB laser, large transportation capacity.

■ Effective Automatic Temperature Control (ATC) and Automatic Power Control (APC) of the laser to ensure stable operation.

■ Microprocessor control and monitor

■ RS-485 interface for remote monitoring and control

■ 45~1000 MHz bandwidth

■ RF pre-distortion circuit for excellent CNR and low distortion performance.
