So we've been getting a lot of inquiries about loopback cables for single-mode MPO testing setups, and this one handles the APC angle with the female connector you mentioned—it's basically built for those QSFP+ transceiver checks where you need a clean, repeatable signal path.
Return loss is north of 50dB on these, which is better than a lot of generic cables we've seen, and the insertion loss stays under 1.0dB (G657A1 fiber) so you're not chasing phantom losses during testing—the 50 insert-pull cycles with IL staying below 0.5dB is pretty telling for real-world bench work.
One thing that matters more than the specs might suggest is the LSZH jacket and that wide temperature range (-40 to +70°C); most buyers go with the 12-core version for standard lab use, though we stock 8/12/24 depending on your batch needs.
The physicall dimensoins are about 65mm by 20mm (roughly the size of a thick thumb drive), and the ferrule endface is PC/UPC—it's not going to confuse with angle-polished termini, but for loopback testing with APC connectors, that's actually what you want.
We usually have stock on the 12-core in about 100 units or so, but confirm lead time (usually 2-4 weeks) if you need the 24-core variant—the MOQ is 10 pieces for custom core counts.
What you get when ordering is each unit individually sealed with a COA showing insertion loss and return loss values, no TDS unless you request it, and the packaing is just basic anti-static bags—they're not pretty, but they work for storage.
You can choose between 8, 12, or 24 cores depending on your testing needs. Just let us know which core count you require when placing the order.
Our MOQ is 50 pieces per core option. If you need a smaller quantity for a trial run, we can sometimes accommodate that — just reach out to our sales team.
Yes, we can include a test report with each batch showing insertion loss <1.0dB and return loss >50dB. Just specify that you need documentation when ordering.
It's rated for 50 cycles with IL staying under 0.5dB, but the connectors are built for over 1000 mating cycles total. So you can push it further if needed, though the loss might increase slightly after 50.
LSZH means low smoke zero halogen, so it's halogen-free and produces minimal smoke if exposed to fire. It's a good fit for indoor or data center environments where safety standards matter.
