Internal Modulator 1550 Fiber Optic Transmitter Support AGC MGC For CATV FTTH

HFC 1550nm Optical Transmitter Support AGC MGC Jizhong Internal Modulator 1550 Fiber Optical Transmitter for CATV FTTH

Product Overview

   JZOT1510N-KII-D series 1550nm direct optical transmitter (insertion type) is suitable for the image, digital and data signal transmission via fiber in the filed of CATV communication. Designed specifically for the transmission of digital or analog signals over medium and short distances; especially suitable for IPQAM optical insertion, enterprise-run program insertion, etc.

Application

Main 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.

Technical Parameters
