FAQ
What faults will occur after the single multimode fiber jumper is connected incorrectly?
If it is: a multi-mode optoelectronic module is connected to a single-mode fiber jumper, then a large loss will be generated at the interface between the optical transmitter and the single-mode fiber, which will significantly reduce the transmission distance and increase the loss by about 6dB-10dB. And generally 100M or Gigabit Ethernet itself has only so much system budget. As a result, the bit error rate is very high and the system is prone to failure. The actual transmission distance will be very short or it will not work directly.
If it is: the single-mode photoelectric module is connected with a multi-mode fiber jumper, in fact, the coupling efficiency of the transmitter is significantly improved. However, due to the increase of modes, the introduction of intermodal dispersion has indirectly reduced the bandwidth and maximum transmission distance. Originally, the 1300nm band single-mode laser module + single-mode fiber defined in ITU Gigabit Ethernet 1000BASE-LX can transmit 5 kilometers. If the multi-mode jumper of OM1 or OM2 is wrongly connected, the Gigabit Ethernet can transmit about 300 meters. If it is wrongly connected to the OM3 jumper, the maximum transmission distance is about 500 meters. Fast Ethernet can even transmit to a maximum of more than 1,000 meters.
In conclusion, misconnecting a single-mode fiber to a multimode module can result in extremely short transmission distances (depending on the actual signal light intensity) or no operation due to increased loss. The wrong connection of single-mode modules to multi-mode fibers will reduce the bandwidth and transmission distance due to the introduction of intermodal dispersion, but it is still usable in short distances (within 300 meters).
