Note:

1. The overload input optical power requirement must be followed; otherwise, the optical module may be damaged.
2. The SFP optical module is optional. The parameters above are reference values. If users select the SFP module supplied by us, the parameters are as shown in the tables. If users purchase other types of SFP optical modules, the parameters may differ.
