Brief Views JHA700-G504G series Building GPON ONU is one of the GPON optical network unit design to meet the requirement of the broadband access network. It apply in FTTH/FTTB to provide the data, video service based on the GPON network. GPON is the latest generations of access network technology. ITU-T G.984 is the standard protocol of GPON. The GPON standard differs from other PON standards in that it achieves higher bandwidth and higher efficiency using larger, variable-length packets. GPON offers efficient packaging of user traffic, with frame segmentation allowing higher quality of service (QOS) for delay-sensitive voice and video communications traffic. GPON networks provides the reliability and performance expected for business services and provides an attractive way to deliver residential services. GPON enables Fiber To The Home (FTTH) deployments economically resulting to accelerated growth worldwide. JHA700-G504G series Building ONU have a high reliability and provide quality of service guarantee、easy management, flexible expansion and networking. It’s fully meet the ITU-T technical standards and have good compatibility with third party manufacturers OLT.
