How to connect MPO Optical Transceiver and LC Optical Transceiver?

There are two interface types of transceivers, MTP/MPO interface and LC interface. For Two transceivers with same interface, they can be connected via MPO cable or LC fiber patch cable. For the connection between transceivers with different interface, they also require the use of MTP-LC Panels and other fiber cabling products. This article will introduce the solution of QSFP+ transceiver and SFP+ transceiver connection.

Solution of direct connection between QSFP+ transceivers and SFP+ transceivers

When a 8-fiber MPO QSFP+ transceiver is connected to 4-duplex LC SFP+ transceiver, we need an 8-fiber MPO to 4 LC Duplex Breakout Cable. However, this solution is only used for short-distance connections in the same cabinet.


Solution of interconnection between QSFP+ transceivers and SFP+ transceivers

  1. A MPO-LC Cassettes is required to connect QSFP+ transceiver via MPO Trunk Cable in one side and SFP+ transceiver via LC Duplex Patch Cable in the other side when use this solution. It should be noted that this is also suggested to be used in short distance applications.


  2. This structured cabling solution allows for patching on both ends of the optical network. QSFP+ transceiver and SFP+ transceiver are connected to MPO Trunk Cable and LC Duplex Patch Cable respectively. Between the MPO Trunk Cable and LC Duplex Patch Cable, it needs MTP-LC Panels, MPO Trunk Cable and LC Duplex Patch Cable to complete the connection.interconnect-1
  3. The final solution is interconnection as well but uses different components at the SFP+ end. It is connected to the SFP + transceiver through fiber optic panels and 8-fiber MPO to 4 LC Duplex Breakout Cable. A disadvantage of using this solution is that flexibility is lost on the SFP+ end because the transceiver ports need to be located in the same chassis.interconnection-2

Solution of Cross-connect Structured Cabling

The final two solutions will allow all patching to be made with maximum flexibility. The second solution is more complex, but more suitable for applications with longer distances between distribution ranges.


The best application for your network will depend on many factors such as design, equipment location, migration path, cost, pathway availability, etc. For additional questions, contact Zebra Cable Technical Support now.
