What is Connectors Loss?

​

Connector loss in power budget calculation is considered as a pair of connectors being connected into an adapters as shown above diagram.
As per TIA/EIA specification,  the maximum loss of paired connector  is 0.75dB.
However, during power budget loss calculation we take maximum connector loss as 0.5dB so as to introduce loss buffer.

Main factors that contribute to the fiber optics connector loss are :

• dirty or contaminated connector (on the ferrule surface)
• damaged fiber optics connectors end ferrule surface
• Improper fiber optics installation or being connected - both pair connectors are not properly aligned

Other factors that may contribute to the higher losses are :

• mismatched fiber cores
• misaligned fiber cores
• mismatch index of refraction

Always clean fiber optics connectors and adpaters with proper cleaning solution i.e. isoprophy alcohol
Use connector ferrule end cap to protect against dust and scratches
