Field applications
BiDi SFP Transceivers (Bi-directional transceivers)
The DNP R-2F/FC can also be used to convert a dual fibre radial link to a redundant
dual path as per Figure 13 by using the BiDi SFP transceivers. The BiDi transceivers
use two frequencies for Tx and Rx on each fibre to carry the Tx and Rx signals on a
single fibre. This application is useful for the following:
-
converting a radial system to a redundant ring on the existing fibre
-
introducing a temporary solution when a single fibre fails on a link.
