RELIABLE MORE COST- EFFICIENT FUTURE PROOFRELIABLE

Different wavelengths behave in different ways. By using the same wavelength for data and OTDR, In-band solution ensures that all measurements are correctly

MORE COST EFFICIENT

• Out-band solution may require additional hardware in SFP, which will increase the cost

• ONT would need a filter to block

FUTURE PROOF

TWDM PON will introduce new wavelengths for data transfer. Finding available wavelength for testing is not an issue for In-band OTDR
