The highest optical power acceptable by the LSH, APC, FC, and UPC connectors

Question:
Among WDM products, Raman amplifiers output high optical power. Therefore the LSH/APC connectors are recommended for Raman amplifiers. In addition, use fiber splicing, whenever feasible, on the ODF to prevent the interface section from being burned out by laser radiation. When interface section is burned out, reflected laser radiation may burn the amplifier. Customers inquire the power ranges supported by various optical connectors.
Root cause: None
Answer.
What is the maximum power supported by LSH/APC connectors?
2000 mW (33 dBm) guaranteed by suppliers of Huawei
What is the maximum power supported by FC/UPC?
300 mw (around 25 dBm) according to experience
