Hardware Description
Introduction

CATV 77EYA Series 3U High Power Fiber Amplifier 64+WDM.

77EYAxx Ytterbium-Erbium series of fiber amplifiers is a high power, multi-output fiber amplifier with a gain spectral bandwidth of 1545-1560nm, designed for CATV or 1-8 consecutive band channels (ITU wavelengths) applications. It provides a flexible and low-cost solution for FTTH coverage of CATV systems in large and medium-sized cities.
77EYAxx can achieve single wavelength transmission of CATV signals, or built-in FWDM to achieve single-fibre three-wave transmission design, which is an important equipment for building CATV large and medium-sized optical fibre transmission networks.

Performance Characteristics
  • Erbium-Ytterbium co-doped double-clad fiber technology and low-noise pump lasers.
  • With display backlight control function, the user can adjust the backlight time as needed.
  • With perfect sound and light alarm function, support dual alarm of indicator light and buzzer.
  • The entire EDFA adopts modular design, making it easy to maintain and manage.
  • Standard network management interface, support WEB network management and SNMP, WEB interface is rich in functions.
  • The 2U product supports total output power up to 41dBm, and supports the output power adjustable function with an adjustable range of +0.5~-4dBm.
  • Optical switch, optical transmitter, RF monitoring and other functions are optional.
  • Optional WDM for triple play function.
  • Dual power supply with one-touch pull-out and hot backup design.
  • Optional time control function and mobile phone remote monitoring function are available.
