What Exactly is Polarity?

Polarity simply means that the Tx on one side should connect to the Rx on the other side and vice-versa. In any installation, it is important to ensure that the transmitter at one end matches the corresponding receiver at the other end. FS provides a number of intelligent solutions that can help you manage and optimize your network and its connectivity.

Maintain Proper Polarity in Base 8/12/24 Structured Cabling

Base-8 Series

Base-8 infrastructure requires Type B components to maintain the correct polarity scheme. Base-8 MTP/MPO is SR4 ready, meaning that the backbone connectivity has the same fibre count as the SR4 transceiver. Please note, although SR4 is an 8 fibre interface, the Base-12 MTP/MPO connector is still compatible with it.

Base-12 Series

Each 12-fibre MTP/MPO translates into six 2-fibre serial optical circuits that require polarity management that can be achieved using one of numerous methods.

Base-24 Series

Base-24 MTP/MPO link is generally deployed for 100G parallel links running over SR10 transceivers. Normally these links are between two high data-rate switches as opposed to switch to server. Base-24 can also be used for lower data rate backbone links such as 10G and 40G but this is normally only in cases where space and install time are the key drivers.
