Brief Views JHA700-G704 series is fiber to the home multi service access GPON ONT. It’s based on the mature, stable, high cost performance GPON technology and has gigabit Ethernet switching, WDM and HFC technology. JHA700-G704 series has a higher bandwidth, higher reliability, easy management and good quality of service (QoS) guarantee with technical performance of equipment meet the ITU- T G. 984 requirements and have good compatibility with third party manufacturers OLT. 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 network 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. 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.  Functional Feature ♦ Support port-based rate limitation and bandwidth control; ♦ In compliant with ITU - T G. 984 Standard ♦ Support data encryption, group broadcasting, port Vlan separation ,etc. ♦ 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 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 PWR Power status On: The ONU is power onOff: The ONU is Power off 2 CATV CATV status On：CATV optical normalOff：The CATV signals are not received 3 LAN1-4 LANport status On: Ethernet connection is normalBlinking: Data is being transmitted through the Ethernet portOff: Ethernet connection is not set up 4 LOS EPON optical signals On: Optical power lower than receiver sensitivity ;Off: Optical in normal 5 PON ONU Register On: Success to register to OLTBlinking: In process of registering to OLTOff: Failed to register to OLT;    Specification Item Parameter PON Interface 1*GPON port, FSAN G.984.2 standard, Class B+Downstream Data Rate：2.488GbpsUpstream Data Rate：1.244Gbps SC/APC single mode fiber 28dB Link loss and 20KM distance with 1:128 User Ethernet Interface 4*10/100M or 4*10/100/1000M 1*10/100/1000M and 3*10/100M auto-negotiationFull/half duplex mode RJ45 connector Auto MDI/MDI-X 100m distance RF Interface Female F-Type Connector Power Interface 12V DC Power supply PONOpticalParameter Wavelength: Tx 1310nm, Rx1490nm Tx Optical Power: 0.5～5dBm Rx Sensitivity: -28dBm Saturation Optical Power: -8dBm Data Transmission Parameter PON Throughput: Downstream 2.488Gbit/s s; Upstream 1.244Gbit/s Ethernet: 100Mbps or 1000Mbps Packet Loss Ratio: <1*10E-12 latency: <1.5ms Business Capability Layer 2 wire speed switchingSupport VLAN TAG/UNTAG，VLAN conversionSupport Port-based speed limitation Support Priority classification Support storm control of broadcast Support loop detection Network Management Standard compliant OMCI interface as defined by ITU-T G.984.4Support WEB management  Management Function Status monitor, Configuration management, Alarm management, Log management Shell Plastic casing Power 4FE+CATV:           <6.5W, 12V/0.6A power supply adapter3FE+1GE+CATV:       <6.5W,12V/0.6A power supply adapter4GE+CATV:           <7.5W, 12V/1A power supply adapter Physical Specifications Item Dimension：170mm(L)*130mm(W)*30mm(H)Item weight：0.3kg Environmental Specifications Operating temperature: 0 to 50ºC Storage temperature: -40 to 85ºC Operating humidity: 10% to 90%(Non-condensing) Storage humidity: 10% to 90%(Non-condensing)  CATV Item Parameter Wavelength 1550nm Optical return loss >45dB Input optical power -18dBm～0dBm RF frequency 47MHz~1000MHz RF output lever 78dBuV (@-12~-2dBm@85MHz) CNR >41dB (@-10dBm@DS22 Channel) CSO >60dBc (@-10dBm@DS22 Channel) CTB >60dBc (@-10dBm@DS22 Channel) RF output return loss >12dB RF impedance 75Ω AGC function Support Network application Typical Solution：FTTH, FTTO Typical Business：INTERNET, CATV Figure: JHA700-G704 (not include wifi) Series GPON ONU Application Diagram  Ordering Information Product Name Product Model Descriptions   4FE+CATV Single fiber JHA700-G704FA-HR501 4*10/100M Ethernet interface, 1 RF interface, 1 GPON interface, built-in FWDM, Input optical power -18dBm～0dBm, support AGC function, Plastic casing, external power supply adapter 4GE+CATV Single fiber JHA700-G704GA-HR501 4*10/100/1000M Ethernet interface, 1 RF interface, 1 GPON interface, built-in FWDM, Input optical power -18dBm～0dBm, support AGC function, Plastic casing, external power supply adapter 1GE+3FE+CATV Single fiber JHA700-G704XA-HR501 3*10/100M and 1*10/100/1000M Ethernet interface, 1 RF interface, 1 GPON interface, built-in FWDM, Input optical power -18dBm～0dBm, support AGC function, Plastic casing, external power supply adapter
