Note:
Among RC831 series devices with optical transceivers for dual-strand fiber, the devices with same
optical transceivers can inter-connect with each other. For example, RC831-120-S1 can be inter-connected with
RC831-240-S1, RC831-240-BL-S1 and other RC831 series devices with S1 optical transceivers.
Among RC831 series devices adopting optical transceivers for single-strand fiber, device with SS13 can
communicate with device with SS15, while device with SS23 can communicate with device with SS25. For
example, RC831-120-SS13 can be inter-connected with RC831-120-SS15, RC831-120-BL-SS15 and other
RC831 series devices with SS15 optical transceivers.
