Huawei SFP B+ (Small Form-factor Pluggable, Class B+) is a type of optical transceiver module, typically used in GPON (Gigabit Passive Optical Network) systems for broadband access, offering good performance (like 1:64 split ratio with a 28dB budget) and compatibility, often found in Huawei OLTs (Optical Line Terminals) or as ONU (Optical Network Unit) modules for devices like cameras, supporting industrial temperatures and Type B protection for reliable data transmission in carrier networks.
Key Characteristics & Uses
GPON Standard: It's a key component in Fiber-to-the-Home (FTTH) deployments, allowing a single fiber to serve multiple users.
Optical Budget: Class B+ provides a ~28dB link budget, supporting up to 1:64 split ratios.
Compatibility: Works with other GPON classes (B, C+) and supports Dying Gasp for power loss notifications.
