… DWDM/OTN Application Scenario
WDM technology has many advantages and is developing rapidly. Main features include:
1)The bandwidth resources of the optical fiber can be used to increase the transmission capacity of an optical fiber several times to several tens of times compared with
… What is OLP in DWDM ( Optical Line Protection) ?
OLP-Optical Line Protection is a product that is used in the protection of network transmission line,the product can realize optical power monitoring and automatic switching.
In optical communication network, OLP real-time monitoring optical power of working optical fiber and standby
… What is the main function of the WDM Transponder (OEO)?
The WDM Transponder(OEO) is widely used in many networks, and the most classical function is wavelength conversion. When adding a CWDM/DWDM Mux to the WDM network, there is a requirement to convert the optical wavelengths like 850nm, 1310nm and 1550nm
… Is it possible to add EDFA and DCM modules in CWDM system？
Is it possible to add EDFA and DCM modules in CWDM system?
No, EDFA and DCM modules can not be used in CWDM system. Since the EDFA and DCM modules‘ operating wavelength range is C- Band (1528~1564nm) which can
… Why do I need DCM in DWDM link?
Why do I need DCM in DWDM link?
Dispersion is a fiber based physical effect that spreads the optical pulse while it travels down the optical fiber. This effcet worsens the signal quality and thus limits the maximum distance you
… Can we add add EDFA to the single fiber DWDM solution？
Can we add add EDFA to the single fiber DWDM solution？
Yes, EDFA modules can be added to the single fiber solution, but they should be used with Red/Blue C Band Filter.
Since the EDFA can only amplify signals from
Why use 100G Coherent Optical Module?
0G coherent optical modules are mainly used for line-side optical transmission in 100G wavelength division systems. Compared with other line-side optical modules, they have good OSNR performance, sensitivity, dispersion tolerance, and DGD tolerance.
DWDM technology using coherent modules is widely
