GPON feature of the access network


PON is the passive optical network with a point-to-multipoint (P2MP) structure, while GPON is the gigabit PON defined by the ITU-T G.984.x series standards, which is also one of the PON technologies. The following GPON features meet carriers' higher requirements on transmission distance, bandwidth, reliability, and low operation costs:

Longer transmission distance: GPON uses optical fibers to transmit data and its coverage radius at the access layer can reach 60 km. Therefore, it can solve the contradiction between distance and bandwidth of twisted pairs.
Higher bandwidth: Each GPON port supports the downstream and upstream rates of up to 2.5 Gbit/s and 1.25 Gbit/s respectively. It meets users' requirements on high-bandwidth services, such as HD TV and live broadcast.
Flexible full-service experience offered by Quality of Service (QoS): QoS controls traffic for different users and user services, ensures multi-service bandwidth for multiple users, and provides differentiated services based on different user services.
Optical splitting: A single fiber in the central office is divided into multiple drop fibers with the help of an optical splitter. The optical split ratio of 1:128 is supported. In this way, GPON saves backbone fiber resources and reduces O&M costs.

ARP proxy feature of the access network
When a PC sends an Address Resolution Protocol (ARP) request to another PC, the request is processed by the access device connected to the 2 PCs. This process is called ARP proxy. ARP proxy is often used for communication between the sub virtual local area networks (VLANs) in a super VLAN.

Which networking features does an MPLS BGP VPN support
When the switch functions as a PE, you can configure the static routing, RIPv1, RIPv2, OSPF, EBGP, and IS-IS multi-instances between the PE and the CE. The switch supports such networking modes as intranet, extranet, Hub&Spoke, CE dual-homing, and hierarchical MPLS BGP VPN.

Accessing the management network port
For details about how to log in to the iMana CLI and WebUI, see the iMana User Guide (Link). For details about how to log in to the iBMC CLI and WebUI, see the iBMC User Guide (Link). Use HTTPS to access the WebUI. Enter https://bmc_ip_address/ in the browser's address box and press Enter. It is not recommended that you enter "bmc_ip_address" in the browser's address box and press Enter. If you enter only the IP address, HTTP will be used by default. The login may fail because HTTP poses security risks.
