GSDCOH Outdoor Converged Optical Hub

Description

    GSDCOH is a small outdoor optical hub, that converges EPON OLT and EDFA. It is suitable for the access network in Cable TV and Telecom system, video surveillance network, enterprise LAN and other network applications, especially for FTTH applications. 
    GSDCOH has the advantages of compactness, flexibility, easy deployment and high performance. Its housing is made of cast aluminum, which has good heat dissipation and meets the requirement of equipment performance in the field environment. 
    GSDCOH provides 2 uplink GE ports, 4 or 8 downlink ports of Gigabit OLT, 1 MGMT port, 1 console port, 1 RS-232 port. Its OLT maximum split ratio of each downlink is 1:64, so the hub can support 256 (1 OLT module) or 512 (2 OLT modules) ONUs.  
    GSDCOH adopts high performance pump laser for its EDFA, and has  APC (automatic power control), ATC (automatic temperature control) and excellent optical path design, to ensure the optimized reliability and stability in outdoor environment. 
    GSDCOH has LCD display, adjust button and LED indicator on EDFA cover. The perfect MCU (micro controller unit) makes the adjustment convenient, intelligent and display clear. 

    GSDCOH supports dual power supplies configuration. 
    GSDCOH can also be configured with a WDM module according to your requirement.
