Brief Views JHA700-E304 series 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. JHA700-E304 series 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.  Functional Feature ♦ Support port-based rate limitation and bandwidth control; ♦ In compliant with IEEE802.3ah Standard ♦ Up to 20KM transmission Distance ♦ 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 LAN port 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 EPON optical interface Meet 1000BASE-PX20+ standard Symmetric 1.25Gbps upstream/downstream SC/APC single-mode fiber split ratio: 1:64 Transmission distance 20KM User Ethernet Interface 4*10/100M or 4*10/100/1000M or 1*10/100/1000M and 3*10/100/1000M 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: 0～4dBm Rx Sensitivity: -27dBm Saturation Optical Power: -3dBm Data Transmission Parameter PON Throughput: Downstream 980Mbps; Upstream 950Mbps Ethernet: 100Mbps or 1000Mbps Packet Loss Ratio: <1*10E-12 latency: <1.5ms Business Capability Layer 2 wire speed switchingSupport VLAN TAG/UNTAG，VLAN translationSupport Port-based speed limitationSupport Priority classification Support storm control of broadcast Support loop detection Network Management Support IEEE802.3 QAM, ONU can be remotely managed by OLTSupport EMS management through OLT SNMP -agent and TelnetLocal management Management Function Status monitor, Configuration management, Alarm management, Log management Shell Plastic casing Power 4FE:                <6.5W, 12V/0.6A power supply adapter3FE+1GE:            <6.5W, 12V/0.6A power supply adapter4GE:                <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-E304 (not include wifi) series EPON ONU Application Diagram Ordering Information Product Name Product Model Descriptions 4FE+CATV Single fiber JHA700-E304FA-HR501 4*10/100M Ethernet interface, 1 RF interface, 1 EPON interface, built-in FWDM, Input optical power -18dBm～0dBm, support AGC function, Plastic casing, external power supply adapter 4GE+CATV Single fiber JHA700-E304GA-HR501 4*10/100/1000M Ethernet interface, 1 RF interface, 1 EPON interface, built-in FWDM, Input optical power -18dBm～0dBm, support AGC function, Plastic casing, external power supply adapter 1GE+3FE+CATV Single fiber JHA700-E304XA-HR501 3*10/100M and 1*10/100/1000M Ethernet interface, 1 RF interface, 1 EPON interface, built-in FWDM, Input optical power -18dBm～0dBm, support AGC function, Plastic casing, external power supply adapter
