Whether optical modules of different wavelengths can communicate with each other？ There are two different answers.

1. can communicate.

"In most cases it should be possible to use, because the receiving end of the optical module is not very sensitive to wavelength"

"Dual fiber optical module, receiving wavelength range is very wide, is completely possible to connect". 

2. can not communicate 

"The fact that there will be a lot of error codes is not recommended" 

"As long as not through the optical amplifier and WDM equipment, is possible to communicate. But the distance is a problem, the optical loss of the two wavelengths is not the same, if the transmission distance is already at a critical value or interoperability of different distances, there may be problems to consider!"

"No way. Considering the different loss and dispersion of transmission in the fiber, generally the same transmission rate, different working wavelengths of optical modules corresponding to the transmission distance is not the same, the transceiver power does not necessarily match, the main reason is that the carrier wavelength is not the same, the signal demodulation may have problems."

Optical modules have become very popular in communication applications. There are many different types of optical modules, and in the field of communication, a superficial question is: Is it possible to dock directly between the many different types of optical modules? What is the case that can communicate for communication?

A general principle of interconnection is: optical modules require reciprocal use, such as the transmission rate, transmission distance, transmission mode and operating wavelength of optical modules at the transmitter and receiver side should be the same.

Referring to some articles to specifically analyze.

Different package: does not affect the docking between optical modules, affect the docking is the package inside the light-emitting components.

Different interface: does not affect the docking between optical modules, but to ensure that the interface between the two ends of the fiber and the respective optical modules match.

Different distances: can not communicate, the light emitted by the long-distance optical module may burn the short-distance optical module, the need to add the middle of the optical attenuator.

Different rates: can not communicate, different rates, optical devices and photoelectric conversion devices are not compatible and can not be identified with each other. 

Different wavelengths: in the case of ensuring the same distance, the same rate, the same single multimode, the same receiving detector, can communicate. However, it is not recommended to use dual-fiber optical modules of Different wavelengths for interworking.

Single-mode, multimode: can not communicate. The underlying transmission standard is completely different.
