GPOA overview

GPOA is a 16-port GPON card, which can be used in the chassis of Fiberhome brand  AN6000-7, AN6000-15, AN6000-17, and AN6000-2.

Gigabit Passive Optical Network (GPON) is a PON technology defined in the ITU-T G.984 series of standards. The figure below shows the network structure of GPON.

GPOA Network

GPOA application

The GPON access technology provides high-bandwidth transmission, overcomes the bandwidth bottleneck in twisted pair access, and caters to users’ demand for high bandwidth services.

Advantages of GPON application:

High density: Supports the split ratio of 1:128. The GPOA card allows access of up to 2048 subscribers.

High bandwidth: GPON can provide a bandwidth of 1.25 Gbit/s in the uplink direction and 2.5 Gbit/s in the downlink direction. The bandwidth can be smoothly migrated to 10 Gbit/s.

HQoS: Ensures that 4K-resolution video programs are not suspended in case of bandwidth congestion.

FEC functions: Enhances fault tolerance of the system to ODN errors.


GPOA hight-lights

Supports Type B and Type C protections to ensure the reliability of mobile backhaul services as well as government and enterprise customer services.
Supports clock synchronization, and provides a low-cost solution for mobile backhaul services.
Transmits data in an efficient way:
Encapsulates all the data to be transmitted into 125 us frames (fixed length frames) with the new GEM encapsulation structure, which uses fewer transmission overhead bytes and improves the transmission efficiency.
The transmission efficiency can reach 93% when the downlink rate is 2.5 Gbit/s and the uplink rate is 1.25 Gbit/s.
Provides clock and time synchronization with high precision. Uses the system time transfer protocol defined in IEEE 802. 1as, and supports IEEE1588 V2.

Standard compliance Conforms to ITU-T G.984 series of standards, with good interoperability.
Transmission rate Uplink: 1.25 Gbit/s

Downlink: 2.5 Gbit/s

Wavelength Uplink: 1290 nm to 1330 nm u Downlink: 1480 nm to 1500 nm
Maximum transmission   distance 60 km
Maximum differential fiber   distance 40 km
Maximum split ratio  1:128
Detection of optical power  Supports the RSSI detection.
Detection of rogue ONUs  Supports automatic detection and location of ONUs that constantly emit light.
Compatibility  Supports various kinds of ONUs, such as SBU, SFU, MTU, cassette MDU, and MDU which can accommodate cards.
DBA function  Dynamically allocates bandwidth according to subscribers’ traffic status.
Reliability  Supports Type B, Type C, and Type C dual-homing protections.
Throughput  Uplink throughput: ≥1100 Mbit/s
 Downlink throughput: ≥2400 Mbit/s
Transmission delay When the split ratio is 1:32, the uplink average transmission delay (when the traffic is no more than 90% of the system throughput) is less than 1.5 ms (packets with the size between 64 Bytes and 1518 Bytes are counted).
 The downlink average transmission delay (when the traffic is no more than 90% of the system throughput) is less than 1 ms   (packets of all sizes are counted).

    I choose the C+ module compared to C++, it is cheaper.
