47~1000MHz Catv Optical Transmitter Internal Modulation HFC Equipment

47~1000MHz Internal Modulation 1550nm Optical Transmitter With SNMP For HFC Network

Performance Features

• It has customized ITU-T standard wavelength.
• It is to improve pre-distortion designed by CSO in 1550 system.
• Integrated combiner has FWDM and broadband,which is applicated in IPQAM signal input
• When SBS threshold is more than 16dbm, in certain of transmission distance, there is no changes in system, and it can be effective instead of external transmitter.
• All key working parameters are display by front LCD panel.
• With RJ45 network interface,19”1U standard frame.
