MPO Loopback
MTP®/APC 8F/12F/24F Singlemode Fiber Optic Loopback
The BWNFiber MTP®/APC Singlemode Fiber Optic Loopback provides a precision multi-fiber return path for singlemode APC interfaces. Available in 8F, 12F and 24F, it is intended for low-reflection verification of MTP/APC ports used in telecom, DWDM and high-density singlemode systems. APC polish supports higher return-loss performance compared with UPC singlemode loopbacks, helping validate sensitive singlemode parallel links. Each unit is built on G.657A2 fiber and 100% factory optically tested.

FAQ
Frequently Asked Questions
Why APC instead of UPC for this loopback?
APC is used when the equipment interface is APC and higher return loss is required. Do not mix APC and UPC on the same connection.
Is MTP® the same as MPO?
MTP is a high-performance MPO-style connector brand (US Conec). This product is specified as MTP® compatible with APC polish.
What return loss should I expect?
≥ 60 dB for this APC singlemode series.
Can you supply pinned or unpinned versions?
Gender and pin configuration are confirmed with the customer at inquiry/order stage to match the port under test.
