ZBL5811T 1550nm External Optical Transmitter

Description

ZBL5811T1550nm external modulation optical transmitter is a high-end product that is applied to CATV optical network for long-time stable operation. It optimizes the optical modulator circuit and pre-distortion circuit to provide excellent performance.

Features
The external modulator and the laser are both imported from USA or Japan
Perfect SBS suppress circuit and adjustable SBS in 13,16, 18,apply for different types of CATV network
Excellent pre-distortion circuit ensures the best CTB and CSO when the CNR is in high standard
AGC and MGC function
Automatically temperature control on shell
The function of laser monitoring, fault alarm and network management by the inner software
RJ45 and RS232 standard interface
Double power supply that can be switched automatically.
