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).

Distance: SFP modules are available for various transmission distances. Common distance ranges include short-reach (up to 100m), medium-reach (up to 10km), long-reach (up to 40km), and extended-reach (80km+). The fiber type and wavelength play a role in determining reach. An SFP (Small Form-factor Pluggable) module transmits data over fiber using specific wavelengths and power levels, which directly influence how far the signal can travel before degradation occurs. Therefore, when selecting fiber patch cords for optical modules, it's essential to choose the type that matches the optical module to avoid unnecessary waste or loss. Data rates range from 155 Mbps to 6 Gbps and even up to 10 Gbps. Transmitter optical sub-assemblies (TOSAs) and laser drivers may have different resistances in a given application, so the reflection could be.
