2 x BIDI 3 Pin XLR Balanced Audio Over Fiber Optic Extenders, Bidirectional Audio to Fiber converters Single Mode 20Km(12.4mi),SC Fiber Connector,A Set

TIP:This model can be compatible with multimode fiber up to 500m, it must require your multimode fiber quality is in good condition, don't have large loss and don't use longer beyond 500m, as regular multimode fiber have large loss which will be caused the transmission distance shorter. Larger loss, shorter transmission distance.
We suggest you using single-mode fiber instead of multimode fiber, As single-mode have tiny loss, which can be transmission longer up to 20Km. if multimode is mandatory for you,please try to decrease your fiber loss, minimize your fiber loss as much as possible.
