FiberHome GM8B XG-PON Card

Fiberhome GM8B overview

GM8B is an 8-port XG-PON and GPON combo card, which can be used in the chassis of Fiberhome brand OLT AN6000-7, AN6000-15, AN6000-17, and AN6000-2.
As a next-generation enhanced GPON technology evolved from GPON technology standardized in ITU-T G.984, XGPON caters to the demand for high-bandwidth services. The figure below shows the network structure of XG-PON.
Combo PON adopts the new WDM1r technology to achieve optical wave splitting, and one device can meet the bandwidth requirements from high to low of different subscribers in a unified area. The self-adaptation of GPON & XG-PON is realized by inserting different optical modules into each PON port, which is the best choice for ISP companies under the current wave of network upgrades.

Product Features

• GPON & XG-PON Combo access: GPON and XG-PON ONUs can be connected to the same service card.
• Smooth upgrade: XG-PON service cards can replace GPON service cards with little configuration change. Accordingly, services can be migrated smoothly.
  Software and hardware compatibility: Bandwidth can be upgraded without replacing subracks. Various PON service cards can coexist in a subrack.
• Clock and time synchronization with high precision: Uses the system time transfer protocol as defined in IEEE 802. 1 as supports synchronous Ethernet (SyncE), IEEE1588 V2, and 1PPS+ToD.
• Overall protection: Supports backbone fiber protection (Type B) and all-fiber protection (Type C), with a switching time of no more than 50 ms.
• Efficient data transmission: Encapsulates all the data to be transmitted into 125 us frames (fixed length frames) with a new GEM encapsulation structure, which uses fewer transmission overhead bytes and improves the transmission efficiency.

Application Scenarios

1. Legacy GPON Upgrade in Japan

A Japanese telecom integrated FiberHome GM8B Boards into AN6000-17 OLTs for Tokyo’s urban residential areas. The 8-port GPON/XG-PON combo card enabled smooth migration from legacy GPON, delivering 10Gbps downlink/2.5Gbps uplink speeds for 4K IPTV and cloud services. With 1:256 splitting ratio and 60km transmission, it served 2,048 subscribers per board while reusing existing ODN infrastructure. Type B/C PON protection (≤50ms switching) ensured 24/7 reliability, and 1588v2 synchronization guaranteed high-quality video calls—supporting the operator’s cost-effective F5G transition.

2. Mixed-Service Access in Nigeria

A Nigerian ISP deployed GM8B Boards in AN6000-07 OLTs for Lagos’ suburban mixed-use districts. The card’s dual-mode adaptability (GPON/XG-PON) catered to both residential broadband and small enterprise cloud needs. WDM1R wavelength splitting optimized bandwidth allocation, while optical power detection simplified remote maintenance. Hot-swappable design minimized downtime, and backward compatibility with GPON ONUs protected existing investments. This solution efficiently covered scattered communities, meeting medium-scale multi-service demands without new fiber deployment.
