Fiberhome EC8B overview
The EC8B PX20+ is an 8-port GPON OLT interface board, which can be used in the Fiberhome AN5516 series OLT: AN5516-04, AN5516-06, AN5116-06B/AN5516-01. It works with the optical network terminal (ONT) to provide EPON access service. Also, it can work with some optical network unit (ONU) or MxU to provide GE/FE Ethernet service. This board comes with PX20+ SFP modules, but you can also choose one that comes with Epon SFP PX20++. If comes with PX20+, supports ONT/ONU access of up to 512 subscribers. If comes with PX20++, supports ONT/ONU access of up to 1024 subscribers.
Product Features
- High Density & Capacity: 8 EPON service interfaces per card. Supports high split ratios (e.g., 1:64, up to 1:128) for efficient fiber sharing. Manages 1024 T-CONTs and 4096 GEM ports per PON port.
- Performance & Quality of Service (QoS): High Traffic Management (TM) performance with 1024 queues and 356 schedulers per port. Supports H-QOS and color-sensitive RED/WRED discard algorithms for traffic control.
- Power Efficiency: Features a newly developed, low-power EPON MAC chip, reducing consumption by about 30%.
- Reliability & Protection: Supports Optical Line Protection (OLP) switching. Provides PON MAC chip-level protection (intra-card and inter-card).
- Clock & Time Functions: Receives 1PPS+TOD signals and transmits them to ONUs, supporting IEEE 1588 V2.
- ONU Management: Supports ONU power-saving management as per G.987.3 standard.
Application Scenarios
1. Urban FTTB Multi-Service in Vietnam
A Vietnamese telecom integrated Fiberhome EC8B Boards into AN5516-06 OLTs for high-rise residential buildings in Ho Chi Minh City. The 8-port EPON card’s 1:64 splitting ratio efficiently served 512 subscribers per board, delivering gigabit data, VoIP, and IPTV. Equipped with PX20+ modules, it supported 20km transmission, covering building clusters. Its 64 kbit/s DBA granularity ensured fair bandwidth allocation, while 1588v2 synchronization guaranteed smooth video calls. Optical line protection switching minimized downtime, aligning with the operator’s goal of reliable triple-play services for dense urban communities.
2. Rural & Small Business Access in Colombia
A Colombian ISP deployed EC8B Boards in AN5516-04 OLTs to connect rural towns and small enterprises in the Andes. The board’s PX20++ module compatibility extended coverage to 20km, serving scattered users. With support for 1024 subscribers per board and 4K VLANs, it handled mixed traffic from home browsing and business cloud applications. Low power consumption (≤50W) worked with local solar power systems, and SC/PC optical interfaces simplified maintenance. Intra/inter-card MAC protection ensured stability in remote areas, bridging the digital divide cost-effectively.
