12 Fiber MPO/APC Loopback - 9/125µm Singlemode OS2
MPO Loopbacks are primarily used in testing by supplying a looped signal that tests both transmit and receive functions within fiber optic applications, more specifically parallel optics 40/100G networks. The development of fiber optic loopback components has greatly improved testing practices throughout the Telecom sector.
By using fiber Loopbacks, you link the signal emitted by your transceiver to the receiver on the same device for 40/100G SR4/SR10 transceiver interfaces. Acquiring bi-directional data on the cable or device under test, streaming the Qualification/Certification process.
Fibertronics, Inc.’s MPO loopbacks come in Standard or Low Loss plug performance. They can be customized to meet requested fiber arrangement and gender. This item can be ordered in singlemode or multimode OM1, OM3, and OM4 fiber types. The loopbacks are factory tested to meet TIA 568 industry standards. Singlemode fiber is ITU-T G.652.D compliant, tested at 1310/1550nm. Multimode loopbacks are also tested to industry standards and meet or exceed TIA 492AAAD for OM4 and TIA 492AAAC-B for OM3. Multimode loopbacks are tested at 850/1300nm. Different housing color options are also available. You can inquire about different designs with your sales rep.
MPO loopbacks can be implemented in Campus Networks, Data Centers, OTN, and PON networks. This product can also be used with Optical DTS monitoring systems, giving a comprehensive view of network performance. They are very useful for solving difficult physical connection failures. Altogether, using fiber loopbacks is a labor-saving, simplified, efficient way for testing. Having a variety of loopbacks in every fiber mode, gender, and polarity available will modernize the way you certify fiber networks.
