Можно ли смешивать оптические модули BIDI с другими оптическими модулями??

Нет, BIDI optical modules must be used in pairs. For example SFP-XG-LX-SM1270-BIDI must be used in pairs with SFP-XG-LX-SM1330-BIDI, otherwise the optical module will not work properly. For the supported BIDI optical module models and the models that can be used in pairs, please check the hardware installation instructions of the device.
