Description
TT-1550H series 32-Port 20dBm 1550nm PON&CATV WDM EYDFA Optical Amplifier
TT-1550H series EDFA optical amplifier is the latest optical transmission system equipment, realizing to combine optical signal OLT XPON/XGS-PON and 1550nm CAT, and amplify the CATV signal as well. The optical input number: 1 port of CATV or 2 redundant CATV inputs + 32 ports PON input ports. 32 ports outputs of 1550nm+1490nm/1310nm & 1270/1577nm combine output, of which the total output power range of 1550nm is 27 ~ 42dBm. Multiple output power can be matched according to user demand.
High-power TT-1550H series WDM EDFA is well compatible with the OLT/ONU of HUAWEI, ZTE, FiberHome, etc and no data is lost, which owns high cost performance. It is mainly used for XPON / XGS-PON structure fiber to home(FTTH) and fiber to the building(FTTB).
TT-1550H series Key Features
Top quality: Adopt multi-mode high-power pump laser and the power is optimized through software, which makes the system achieving excellent CNR.
Reliability: Adopt 19″ 2U/3U standard chassis, built-in high performance modular switching power supply, can work in AC165 ～ 265V city network voltage. DC 48V hot-swappable power supply option is available as well. Dual hot and reserved power supply with Chassis automatic heat dissipation control.
Intuitive: The built-in microprocessor monitors the working status of the pump laser, and the working parameters are displayed on LCD.
Network management Interface: Web transponder is line with the national standard and compatible with the SCTE HMS standard, achieving WEB monitoring function. The red warning symbol is displayed on the web page, which is convenient for troubleshooting.
Adjustable output optical power: Advanced design enables a large adjustable range of output power, and power can be lowered by 0 ~ -3dBm.
Plug-in WDM modular: Integrated FWDM module, CATV, GPON, EPON, XGS-PON (customized). One fiber with multi-waves is convenient to use.
Built-in optical switch option (customized): There are automatic (prefer) or manual (force) switch mode when CATV signal has main path A and redundant path B optical switch input (OPT SWTTCH). Automatic mode uses the main path A by default, it switches to redundant path B if A input power fails.
