This module code SPT-SFP+LR SFP+ 10G-LR 1310nm 10KM Supports DDM options

  Sopto provides 10G fiber transceivers, SFP+, XFP, XENPAK and X2, all of them have Digital diagnostic monitoring (DDM) function, and it provides a user with critical information concerning the status of the transmitted and received signals.


  DDM gives the end user the ability to monitor real-time parameters of the 10G SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

Other type of fiber optic transceiver

For other features, the fiber optic transceiver also can be divided into other different class.  Some fiber optic transceiver modules are designed with DDM function, but some not. Some is used in CWDM, but some is used in DWDM or bi-direction (WDM). Most fiber optic transceiver modules supplied by SOPTO support DDMAdditionally, there is copper fiber optic transceiver. Most fiber optic transceivers supplied by SOPTO support Fibre Channel, LTE, SDH/SONET, CPRI and OBSAI applications.

Optical Module Frequently Asked Questions:

Take 1.25G SFP module as an example. 1. Optical power badness: 2. Eye diagram badness; 3. Receiving end badness; 4. Working current badness; 5. Program Programming failed;

Common-Badness Reason Judging Method

1. Visual Method: Check the faulty module appearance. Whether there is obvious damage, component burned black, dehiscence, leakage, even tin or not.2. Comparative Law: Use certain tools and a good module. Test the good module and the target module. Mainly analyze circuit parts or components' resistance, voltage, waveform, etc. Then make a comparison.3. Substitution Method: To replace the components of the module; then to analyze the change of operating parameters.  4. Others
