GPON optical module, also known as GPON SFP transceiver, is a small and pluggable module that plays a critical role in Gigabit Passive Optical Networks (GPON). It converts electrical signals into optical signals over fiber optic cables in the GPON network. Huawei GPON module has 3 types of Class B+, C+ and C++, price is different based on different modules equipped.
Advantage of the GPON Optical Modules
High Bandwidth: Enables transmission of large amounts of data over long distances, supporting applications like high-speed internet, video streaming, and VoIP.
Cost-Effective: Since GPON is a passive technology, it eliminates the need for expensive amplifiers in the network, reducing overall deployment and maintenance costs.
Scalability: A single OLT can connect to multiple ONTs, offering scalability for expanding network coverage.
Security: Data traveling through fiber optic cables is less susceptible to interference compared to traditional copper cables.
Specification of Huawei B+ C+ C+ modules
| Type | B+ | C+ | C++ |
| Operating Wavelength | Tx: 1490 nm Rx: 1310 nm |
Tx: 1490 nm Rx: 1310 nm |
Tx: 1490 nm Rx: 1310 nm |
| Encapsulation Type | SFP | SFP | SFP |
| Port Rate | Tx: 2.49 Gbit/s Rx: 1.24 Gbit/s |
Tx: 2.49 Gbit/s Rx: 1.24 Gbit/s |
Tx: 2.488Gb/s Rx: 1.244Gb/s |
| Minimum Output Optical Power | 1.50 dBm | 3.00 dBm | 6.00 dBm |
| Maximum Output Optical Power | 5.00 dBm | 7.00 dBm | 10.00 dBm |
| Maximum Receiver Sensitivity | -28.00 dBm | -32.00 dBm | -35.00 dBm |
| Optical Connector Type | SC/PC | SC/PC | SC/UPC (Compatible with SC/PC) |
| Optical Fiber Type | Single-mode | Single-mode | Single-mode |
| Overload Optical Power | -8.0 dBm | -12.0 dBm | -15.0 dBm |
| Extinction Ratio | 8.2 dB | 8.2 dB | 8.2 dB |
| Split Ratio | 1:64 | 1:128 | 1:128 |
In summary, the fours modules differ from optical port, receiver sensitivity and split ratio. C++ is the highest performance, B+ is the lowest.
GPON board of Huawei MA5600T and MA5800 OLT, such as GPBD, GPFD, GPUF, GPSF, GPHF are normally inserted with C+, if C++ modules required, price will be higher; B+ modules is not recommend, because it is low performance but high fault rate.
