time

The 32WSS-L card supports OChSPRing protection. This implies that the optical plug-in module needs to perform a switch fast enough to allow a total unit switching time of less than 10 ms.

The 32WSS-L is a double-slot card that has three LEDs on its front panel.

2.2.3.3 32DMX Card

Table 2-10defines the 32DMX card optical parameters and the maximum insertion loss allowed.
