Due to its smaller size, SFP obsoletes the formerly

Modules of GBIC and SFP formats have memory storage based on typical EEPROM. With the help of SFPTotal PG-2GS programmer (programming board, 5V DC PS, USB, GBIC, SFP) you will be able to count, edit and upload the firmware to the memory of the transceiver, using specialized software SFPTotal Wizard. With this solution it is possible to reprogram multiple modules and working configurations in accordance with the MSA standards. It is a perfect solution to solve your problems with transceivers of lower price range.With the advent of transceiver of SFP 1.25Gb/s, XFP, QSFP formats with 10G speed and faster manufacturers refused the use of EEPROM to store firmware in the memory of transceivers.
SFP transceivers are available with a variety of transmitter and receiver types, allowing users to select the appropriate transceiver for each link to provide the required soldered-in optical reach over the available optical fiber type (e.g. multi-mode fiber or single-mode fiber). Optical SFP modules are commonly available in several different categoriesThe enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP that supports data rates up to 10 Gbit/s. The SFP+ specification was first published on May 9, 2006, and version 4.1 published on July 6, 2009.SFP+ supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. It is a popular industry format supported by many network component vendors.
