Will A Single Mode Connector Work On Multi-mode Cable? |
|
Answer» The answer is MAYBE you can USE SM connectors on MM but NOT the reverse. SM connectors are made to tighter tolerances - as is SM fiber - so the ferrule hole may be too small for some MM fibers. MM connectors have bigger HOLES for the fiber and will have high loss (>1dB) with SM. ALSO MM connectors may not be PC (physical contact) polish - terrible for return loss. MM fiber may not fit the SMALLER hole in SM connectors. The answer is maybe you can use SM connectors on MM but NOT the reverse.
