We'll start with insertion loss of ≤0.35dB and return loss hitting ≥55dB for single-mode, which is what most data center folks ask about first — and those numbers hold up across at least 200 matings with less than 0.3dB change actually.
You're looking at 2 to 24 cores per assembly, and we typically run ribbon or mini round cable with PVC or LSZH jacket — just tell us your preference, the 12-core ribbon is pretty much the most popular for backbone runs, but it depends on your density requirments.

Polishing options are APC or PC, and the precision MT ferrule handles alignment well — one thing you'll notice is that for high-port-count panels, the 24-core version saves a ton of space compared to individual connectors, but it's not ideal for short patch cords under a meter because the bend radius gets tight.

4, our company supply full documentation with every order — COA with HPLC data showing the specs are within tolerance, plus SDS and TDS if you need them for your compliance team, and the RoHS and ISO9001 certs cover all batches shipped.

Payment terms are net 30 for established accounts after credit check, otherwise wire transfer before shippng — lead time is usually 15 to 20 working days form order confirmation, but we've got roughly 500 units or so in stock for the common configurations if you need them faster.
Shipping is via DHL or FedEx for smaller orders, or our company can palletize for LTL freight if you're ordering 50 units or more — just include your preferred carrier in RFQ, and we'll quote accordingly.
Yes, 12 cores is a very common config for our MPO series—it falls right within our 2-24 core range. No custom setup needed, just specify core count when ordering.
For a bulk order like that, typical lead time is around 15-20 working days. We can speed it up if you need it faster—just let your account manager know.
Absolutely, we include a test report with every bulk shipment. You'll see the actual ≤0.35dB insertion loss and ≥55dB return loss values for SM cables, all measured per batch.
MOQ for 24-core OFNR MPO cables is 100 pieces. If you need less, we can sometimes work out a smaller sample run, but standard bulk pricing kicks in at 100.
Keep them in the original packaging, in a clean dry place between -10°C and 60°C. Avoid stacking heavy boxes on top to prevent lateral pressure damage.
