Actually not, because the connection port of SFP optical module is flat, so It can only be connected with the fiber jumper of PC and UPC, if it is connected with the fiber jumper of APC, it will cause invalid connection or network failure. Optical fiber jumper is an indispensable connecting cable in optical fiber wiring., do you know what. Before introducing APC, UPC and PC connectors, it should be aware that In order to maximum couple the fiber light output from the transmitting fiber to the receiving fiber, the two end faces of the optical fibers must be accurately connected. Figure 1: Picture of APC, UPC, PC connectors.
Fibre Channel transceivers, also called FC optical modules, are specialized devices designed for high-speed, reliable, and lossless data transmission within SANs.

is a later form of EEPROM. In the industry, there is a convention to reserve the term EEPROM to byte-wise erasable memories compared to block-wise erasable flash memories. EEPROM occupies more die area than flash memory for the same capacity, because each cell usually needs a read, a write, and an erase, while flash memory erase circuits are shared by large blocks of cells (often 512×8).
