 Passive Optical Port Replication in Your Data Center

Fiber port replication is when a patch panel “mirrors” an active switch. This creates a direct relationship between the active switch and the passive fiber patch panel. This is a good thing for several reasons. We are going to share the top three reasons with you today.

The Top 3 Reasons You Should Use Port Replication in Your Data Center:


Make Moves Adds and Changes (MAC’s) less risky

When port replication is utilized in conjunction with a recommended TIA-942 structured cabling design, patching for MAC’s are physically closer together and there is an exact one to one relationship between the hardware and panel ports. This significantly reduces the risk of human error (which happens to be the most common cause of network downtime).

Reduction of cabling “mess” in front of the switch

With port replication, the switch can be cabled up neatly and then it does not need to be touched again. Typically switches are cabled up nicely for the initial installation; but over time when port assignment changes are made, the neat cabling turns into “spaghetti.” With port replication, the active hardware can remain untouched until something physically needs to be replaced (a fan, power supply or blade).

Relieves stress on fiber cabling

Fiber cabling is very sturdy, but can be put under extreme stress when proper installation and management is not utilized. When the cabling is not managed properly, and patch cords become intertwined. The weight of the cabling will pull on the connectors at the transceiver contact. This can lead to intermittent channel errors and worst case will cause network downtime.
