Overview JHA700-G508F series GPON ONT is one of the GPON optical network unit design to meet the requirement of the broadband access network. It apply in FTTH/FTTO 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-G508F series 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.  Features ♦ Support port-based rate limitation and bandwidth control; ♦ In compliant with ITU - T G.984 Standard ♦ Support data encryption ♦ Support group broadcasting ♦ Support Dynamic Bandwidth Allocation (DBA) ♦ Support ONU auto-discovery/Link detection/remote upgrade of software; ♦ Support port mode of VLAN configuration ♦ Support power-off alarm function ,easy for link problem detection ♦ Support broadcasting storm resistance function ♦ Support port isolation between different ports ♦ Support port flow control ♦ Support ACL and SNMP to configure data packet filter flexibly ♦ Specialized design for system breakdown prevention to maintain stable system ♦ Support software online upgrading ♦ EMS network management based on SNMP ,convenient for maintenance    Product interface and LED definitions Indicator Description 1 LAN1-8 LAN port status On: Ethernet connection is normal;Blinking: Data is being transmitted through the Ethernet port;Off: Ethernet connection is not set up; 2 LOS GPON optical signals On: Optical power lower than receiver sensitivity ;Off: Optical in normal 3 PON ONU Register On: Success to register to OLT;Blinking: In process of registering to OLT;Off: In process of registering to OLT; 4 PWR Power status On: The ONT is power on;Off: The ONT is Power off;  Specification Item Parameters Specification Interface PON Port 1*GPON port, FSAN G.984.2 standard, Class B+Downstream Data Rate：2.488GbpsUpstream Data Rate：1.244Gbps SC/UPC single mode fiber 28dB Link loss and  20KM distance with 1:128 Ethernet Port(LAN) 8*FE Auto-negotiation RJ45 portsFull Duplex / Half-Duplex Auto-MDI/MDI-X Transmission Distance 100 Meter Power Supply Port 12V DC supply power Management Network Management Standard compliant OMCI interface as defined by ITU-T G.984.4Support WEB, Telnet local management Management Function Status monitor, Configuration management, Alarm management, Log management.
