What does esfp optical module mean? Is a small pluggable fiber optic module, usually used in connection with LC or SC fiber. There are also enhanced SFP, refers to the SFP with voltage, temperature, bias current, transmit optical power, receive optical power monitoring function.
Of course, now all the SFP with these monitoring functions, so also the esfp are unified called sfp.
Two, esfp optical module and general sfp optical module difference in which
In the main function of the business there is no difference, as long as the optical power, sensitivity, distance is the same, is interchangeable use.
The difference is mainly esfp optical module increased diagnostic function:
Optical module in the process of using other factors will affect the function of the module makes the communication data error. The working temperature of the optical module, the bending of the fiber will affect the optical power and the service life of the optical module itself.
The need for real-time monitoring of the working status of the optical module, that is, to monitor the optical module of the five parameters of the indicators:
1, power supply voltage
2, temperature
3, receive optical power
4, transmit optical power
5, laser bias current
Then will monitor the value of the value of the optical module under normal operating conditions and the required value of the range of Then the monitored values are compared with the range of values required by the optical module under normal operating conditions, and if they are not within the required range, an alarm will be raised to show that the optical module is in a bad condition, and the switch will stop sending data until the optical module is in a normal condition before sending or receiving data again.
