EPON ONU 1GE+CATV Single Fiber RF (DT-EONU+1GE+CATV SF RF)

Description 

EONU 1GE+CATV SF RF(DT-EONU+1GE+CATV SF RF) is fiber to the home multi service access EPON ONU. It’s based on the mature, stable, high cost performance EPON technology and has gigabit Ethernet switching, WDM and HFC technology. DT-EONU+1GE+CATV SF RF has a higher bandwidth, higher reliability, easy management and good quality of service (QoS) guarantee with technical performance of equipment meet the IEEE802.3ah requirements and have good compatibility with third party manufacturers OLT.EPON technology is a kind of emerging technology which takes advantage of PON technology and Ethernet technology also is a kind of point to multi-point network technology. OLT through the passive optical network to connect multiple ONU with single fiber bidirectional technical can rarely used fiber resources to meet the operators of the multi-user access requirements.It adopts single fiber WDM technology with downlink wavelength 1550nm and 1490nm, uplink wavelength 1310nm . It only needs one-core fiber to transmit data and CATV service.
