Given the equation of the parabola is $y^{2}=8x$,
(1) Line $l$ passes through the focus $F$ of the parabola and is perpendicular to the $x$-axis. $l$ intersects the parabola at points $A$ and $B$. Find the length of $AB$.
(2) Line $l_{1}$ passes through the focus $F$ of the parabola with a slope angle of $45^{\circ}$. $l_{1}$ intersects the parabola at points $C$ and $D$. $O$ is the origin. Find the area of $\triangle OCD$.
