No. The STM1E-SFP22 is a custom version of the STM1E-SFP so is not visible on Maxim's public website. All information related to the SFP22 version is confidential and this includes 1) the name of the customer for which the custom version was developed and 2) differences between SFP22 and the public versions below:
Public versions ending in 02 and 08 remain available:
STM1-SFP08
STM1-SFP02
Customers cannot replace the SFP08 or SFP02 with the SFP22 version - they will not work properly.
