ED5229GT-E/GTRE Series

EDFA Optical Booster

GPON EDFA with WDM for IP (OLT) wavelengths Multi Optical Outputs
(With Pluggable Cooling fans, fan speed monitoring & alarm / for Outdoor Cabinet Environment)

The ED5229GT-E / GTRE Series is a high-power multi-ports EDFA optical booster with gain spectrum bandwidth from 1545 to 1563 nm for the HFC network. It is designed for the amplification of 1550nm single channel or multi-channel wavelengths (ITU wavelength) with WDM for IP (OLT) signal overlay. The integrated WDM devices are used for combing GPON (IP) signal wavelengths of 1310nm (upstream) & 1490nm (downstream) with a 1550nm broadcasting signal in the same fiber. The ED5229GTRE model has an additional built-in optical receiver for directly monitoring the 1550nm signal. The units are specially designed with ruggedized components for operation from -5°C to +65°C which is suitable for both indoor and outdoor cabinet environments. The ED5229GT-E/GTRE has a very compact by design that includes pluggable cooling fan modules on the sides with fan speed monitoring and fan failure alarms. The pluggable power supply modules have on/off switches on the front panel. All-optical connectors are positioned at a 60-degree angle to the front panel surface for easy fiber routing. It provides full front-panel access functions including the power supply connections. It is 2 RU in height and by using mounting adaptor brackets it will work on either a 21” and 23” rack and can be installed vertically or horizontally. This series of EDFA offers a flexible solution for broadcasting large area coverage of metropolitan and medium-sized cities.
The ED5229GT-E/GTRE EDFA adopts the world’s top-class pump lasers and the American brand OFS’ erbium-doped optical fiber. Perfect APC control, excellent design in the ventilation and efficient heat-dissipation ensure the long life and high reliability of the product. The pump laser will switch off automatically if the input optical signal power is too low or missing, which offers safety protection for the lasers. The LCD display and LED indicators on the front panel provide system information, real-time monitoring and alarm functions for operating this equipment. A RS232 interface is available for controlling the unit from a remote PC by a GUI software. Network management via SNMP protocol is possible using the RJ-45 port on the front panel.
