Brief Introduction
MPO loopback, also called MPO jumper looper, is to pass both ends of a section of optical fiber into an MPO connector, and the optical path enters from several channels and exits from the other channels. The optical path is transmitted inner one connector, that is, the loop function is realized.
This MPO loopback provides an effective and simple solution for the performance test of optical modules (optical transceiver), testing the transmission capability and receiving sensitivity of network equipment, especially the data center link test. The product is a high-density compact type, including 8-core QSFP, 12-core or 24-core, SM or MM MPO male or female. The streamlined and rugged housing design provides greater stability and reliability.
Features
1.SM or MM available ; PC(plane) or APC(8 degree) available.
2.High quality ferrule and accurate alignment PIN and PIN hole.
3.Standard Insertion Loss and Low Insertion loss are available.
4.Connector compliant with IEC 61754-7(Type MPO connector family) and RoHS standard.
Applications
1.Aging test for MPO / MTP network component system.
2.MPO/MTP cabling system test.
3.MPO/MTP system loop test.
4.MPO/MTP optical cable loop detection.
5.40G/100G QSFP optical transceiver test.

Before produce, it is necessary to confirm whether MPO connector is male or female.
Female, without guide PINS Male, with guide PINS
How to confirm the MPO connector what you need is male or female?
| Type1: Connection between MPO and MPO Connection between two MPO connectors, which must be one MPO connector is Female and another one must be Male. |  |
 | Type2: Connection between MPO and optical module You know, All optical modules are self-contained with Guide PIN, it means male MPO connector inside, so when connection between MPO cable and optical module, the MPO connector on cable must be the female connector. |
Packing
NOTE:One ziplock bag for one MPO/MTP loopback.
