We correct the results for WSW2 networks with limited input/output fibers derived in the paper [J. Opt. Commun. Netw., vol. 10, no. 8, p. 675,2018]. The revised results show that when the number of input/output switches is less than the maximum number of frequency slot units occupied by a single connection, a rearrangeable nonblocking WSW2 network with limited input/output fibers (1) consumes fewer middle switches than a WSW2 network with limited connection rates, and (2) reduces the strictly nonblocking result down to at least half.
