sfp-optical module interface introduction ESFP7313-53-DDM1250M single mode 15 km SFP optical module 1. Features: 1310 wavelength FP laser emission InGaAs photodiode reception working speed reaches 1250M compatible with SFP MSA and SFF-8472 industrial standard small package dual LC interface single 3.3V power supply differential LVPECL level input and output TTL signal detection function with hot plug function with digital diagnosis function 2. Application: Routing or server switch backplane using other optical transmission systems 3. Description: ESFP7313-53-DDM optical module is fully compatible with SFP protocol. It shows the characteristics of high performance and low cost, and the transmission rate can reach 1250M. Inside the module, the transmitting part and the receiving part are two completely independent parts. The receiving part includes an InGaAs photodiode (detectable wavelength range from 1100nm to 1650nm), a preamplifier and a post-amplifier, which completes the conversion of the received photoelectric signal into an electrical signal. The transmitting part includes a 1310nm FP laser with backlight feedback. The laser driver IC has an automatic optical power control function, which completes the conversion of the input electrical signal into a stable optical signal. This product is fully compatible with the SFP protocol, such as LC optical interface, 3.3V power supply, and TTL signal detection. 4.
