Huawei OLT Ma5600 & 5608t GPON feature glance

  1. 1. GPON is a point-to-multipoint (P2MP) passive optical access standard that complies with ITU-T G.984.x. A GPON system consists of an optical network terminal (OLT) interconnected to optical network units (ONUs) with an optical distribution network (ODN). Value 1 GPON Service Node Splitter R/SS/R ODN UNISNI IFgponIFgpon OLT ONU ONU CPE The GPON access feature brings the following benefits to carriers: Longer transmission distance: The application of optical fibers can support a transmission radius of 40 km at the access layer, resolving transmission distance and bandwidth issues in twisted pair transmission. Higher bandwidth: Each GPON port can support a maximum transmission rate of 2.5 Gbit/s in the downstream direction and 1.25 Gbit/s in the upstream direction, meeting the usage requirements of high-bandwidth services, such as high definition television (HDTV) and outside broadcast (OB).

Multicast-Server iManager U2000 NGN/IMS Enterprise HQOLT STM-1/E1 GE/10GE E1/GE Splitter ONT FTTH ONU FTTW APPC Intelligent terminal ONU FTTB/FTTC ONU FE/GE PBX FTTOE1/POTS Enterprise Router ONU E1 FE/GE Node B BTS FTTM PLMN PC SDH/ Metro IP Network Application The GPON access feature can be applied in fiber to the building (FTTB), fiber to the curb (FTTC), fiber to the home (FTTH), fiber to the mobile base station (FTTM), fiber to the office (FTTO), and fiber to the Wi-Fi (FTTW) scenarios and support services including voice, data, video, private line access, and base station access. 2 Value Better user experience on full services: Flexible QoS measures support traffic control based on users and user services, implementing differentiated service provisioning for different users. Higher resource usage with lower costs: GPON supports a split ratio up to 1:128. A feeder fiber from the CO equipment room can be split to up to 128 drop fibers. This economizes on fiber resources and O&M costs.
  3. 3. Highlights Type B and Type C Switching Type B switching  Improved switching performance: Switching is performed by hardware, which shortens the switching duration to 50 ms.  Cost effective: Type B switching protects feeder fibers. When compared with type C switching, type B switching can provide the same switching rate at a lower cost. PON 1 GPON PON2  E2E protection: Type C switching can protect the entire GPON network between the OLT and ONUs, featuring high reliability. In single-homing scenarios, the switching duration is shortened to 50 ms.  Geographical-level disaster tolerance: An ONU is dual-homed to two OLTs, further improving system reliability. Chip-level line protection switching ensures high system reliability. PON 1 PON 2 GPON Type C switching 50ms 50ms 3 Unique Upgrade Without Interrupting Services The entire upgrade process does not interrupt services. Step 1: Upgrade control boards. Upgrade the standby control board, perform active/standby switching, and then upgrade the original active control board. In this way, the upgrade of control boards does not interrupt services. CBU OLT MTU LAG M 2:N MA5600T CBUMTU Step 2: Upgrade GPON boards. An MTU or CBU with type B/C switching enabled connects to two GPON boards. Upgrade the standby GPON board, perform type B/C switching, and then upgrade the original active GPON board. In this way, the upgrade of GPON boards does not interrupt services.

High Precision Clock and Time Synchronization 4 OLT ONU 1588ACR Clock signal input eNodeB 1588v2 BTS Supports 1588 adaptive clock recovery (ACR) and 1588v2 clock signal input to implement the 50 pps clock frequency and 100 ns time synchronization precision, meeting usage requirements of various base stations. (1588 ACR does not support time synchronization.) High clock and time synchronization precision meets clock precision requirements for the mobile backhaul service in various network systems.

  5. 5. OMCI Extension for Higher Upgrade Efficiency and Shorter Interruption Time 5 U2000 GPBH/GPFD  ONT upgrade efficiency improved by one time: The time required for upgrading 1000 ONTs connected to one OLT is shortened from 40 minutes to 20 minutes.  Service interruption time shortened by one time: The service interruption time of 3500 ONTs connected to one OLT is shortened from 200s to 100s. Original: low ONT upgrade efficiency New: ONT upgrade efficiency is improved by one time 1996-byte packets Upgrade program or configuration data GPBD 32-byte fragments Only 32-byte of data can be transmitted each time. The packets longer than 32 bytes require fragmentation. A maximum of 1996-byte of data can be transmitted each time, which reduces fragments and improves transmission efficiency. U2000 Highlights 32-byte fragments Longer Transmission Distance: Simplifying ODN Network Deployment and Improving Deployment Efficiency A common GPON board supports only a 20 km differential fiber distance. If the transmission distance is longer than 20 km, different PON ports are required to support transmission ranges from 0 20 km and 20 40 km. This not only complicates network planning but also causes a waste of resources. 0-20km OLT PON 1PON 2 20-40km 0-40km OLT PON 1 The enhanced new-generation chip supports the 40 km differential fiber distance and all PON ports support the transmission range up to 40 km. This not only complies with ITU-T G.984.7 but also simplifies ODN network planning and service provisioning.
