HANSUN CWDM Advantages and Disadvantages
| CWDM Advantages | CWDM Disadvantages |
|---|---|
| Lower power consumption Smaller space requirements Can use SMF fiber or MMF cable Can use LED’s or Laser’s for power Larger individual payloads per channel Smaller and cheaper wave filters Cost savings on start-up and expansion | Less capacity than DWDM Less range Regeneration vs amplification O, A and M functions are not carrier-class |
DWDM Advantages and Disadvantages
| DWDM Advantages | DWDM Disadvantages |
|---|---|
| Maximum capacity system available Maximum distance capability with EDFA’s Repeater “amp” sites can be reduced Pay as you grow expansion Mature O, A and M systems are developed | Need more space Need more power Need high accuracy lasers and wave filters Expensive EDFA’s for amplifiers Start-up costs are more than the equivalent CWDM system |
