Brief Views JHA700-E104GP-BR520 series is C-Data’s for broadband access market based on the introduction of EPON technology passive optical network terminal products. It’s with EPON OLT are used together to provide a complete broadband access solution. 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. JHA700-E104GP-BR520 series fully meet IEE802.3ah and CTC3.0 standard protocol. It has good third-party compatibility to work with the third party OLT, It supports 1Gbps transmission rate up and down and provides users with good QOS, flexible bandwidth allocation of Ethernet services and IP integrated 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 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 PWR Power status On: The ONU is power on;Off: The ONU is Power off; 2 PON ONU Register On: Success to register to OLTBlinking: In the process of registering to OLT;Off: In the process of registering to OLT; 3 LOS EPON optical signals On: Optical power lower than receiver sensitivity ;Off: Optical in normal 4 LAN1-4 LAN Port status On: Ethernet connection is normal;Blinking: Data is being transmitted through the Ethernet port;Off: Ethernet connection is not set up;  Specification Item Parameter PON Interface 1 EPON optical interface Meet 1000BASE-PX20+ standard Symmetric 1.25Gbps upstream/downstream SC/UPC single-mode fiber split ratio: 1:64 Transmission distance 20KM User Ethernet Interface 4*10/100/1000M auto-negotiationFull/half duplex mode RJ45 connector Auto MDI/MDI-X 100m distance Power Interface An external 12V 0.5A/DC power supply adapter 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: 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 Remote management through SNMP and TelnetLocal management Management Function Status monitor, Configuration management, Alarm management, Log management Shell Black metal casing Power Power consumption <6.5W, 12V/0.5A power supply adapter Physical Specifications Item Dimension：158mm(L) x 106mm(W) x 30mm (H)Item weight：0.4kg 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)   Network application Typical Solution：FTTH, FTTO Typical Business：INTERNET, IP Camera   Figure: JHA700-E104GP-BR520 Application Diagram Ordering Information Product Name Product Model Descriptions 4GE JHA700-E104G-BR520 4*10/100/1000M Ethernet interface, 1 EPON interface, black metal casing, external power supply adapter 4GE+PD JHA700-E104GP-BR520 4*10/100/1000M Ethernet interface, 1 EPON interface,black metal casing,,external power supply adapter,With 802.3af POE PD function.
