  In the current paper, we extend our prior research [X. Wu, H. Lin and H.
Zhang, Braid group action and quantum affine superalgebra for type
$\mathfrak{osp}(2m+1|2n)$. Preprint, (2024)], which introduced the Drinfeld
presentation of the quantum affine superalgebra associated with the
orthosymplectic Lie superalgebra $\mathfrak{osp}$ $(2m+1|2n)$ for $m>0$. Based
on this work, our present investigation focuses on its R-matrix presentation.
Moreover, we establish an explicit isomorphism between the R-matrix
presentation and the Drinfeld presentation. In particular, our contribution
extends the investigations of Jing, Liu, and Molev concerning quantum affine
algebra in type BCD to the domain of supersymmetry [arXiv:1903.00204;
arXiv:1911.03496].
