DIRECT ANSWER / 01
MPO is an interface category; MTP is a brand: separate the RFQ fields
MPO describes a multifibre connector interface category; MTP® is US Conec’s brand of MPO connectors. Brand requirements, mechanical mating and complete-link performance need separate confirmation; “MTP/MPO” alone does not establish compatibility or guaranteed loss.
Use this review for data-centre trunks, equipment harnesses, cassettes and substitutions. These are procurement recommendations, not confirmed ARRANEX brand availability, certification or performance claims. Obtain written component-origin and reference confirmation before ordering a specified brand.
SELECTION MATRIX / 02
Purchasing decision matrix
| Item | Identify | Correct action | Avoid |
|---|---|---|---|
| Brand | Specified MTP or an acceptable MPO alternative | Write the brand and permitted substitutions into the BOM | Calling every MPO an MTP |
| Mechanical mating | Full reference, positions, key, pins and end face | Review equipment and mating drawings at each end | Assuming similar appearance proves interchangeability |
| Optical path | Active lanes, polarity and breakout map | Document lanes from equipment to equipment | Replacing a lane map with a brand name |
| Performance | Project limits, method and reference setup | Compare reports under matching conditions | Treating brand marketing as a link guarantee |
| Change control | Component revision, substitution approval and retest scope | Freeze approved components between sample and volume stages | Substituting a connector without approval |
RFQ INPUTS / 03
Minimum inputs a supplier can verify
| Category | Required input or confirmation |
|---|---|
| Minimum RFQ | Application, both references, fibre, count, polarity, length and quantity |
| Brand evidence | Specified components, origin statement, supplier confirmation and substitution rules |
| Acceptance | Approved drawing, inspection, mapping, test conditions and report fields |
BUYER FAQ / 04
Purchasing FAQ
Are MTP and MPO completely different interfaces?
No. US Conec identifies MTP as its brand of MPO connector; check the exact mechanical configuration for mating.
Does MTP guarantee lower total link loss?
Do not infer that from the brand. Compare component grade, mating, connection count and results under a common method.
Must a 400G upgrade replace connectors with MTP?
A rate is not a brand requirement. Review retention or replacement against module interfaces, the complete link and procurement requirements.
Can an equivalent component be substituted?
Use the project approval rules. Review configuration, origin, samples and acceptance before written approval.
Is “MTP 12F” enough for an RFQ?
No. Include both-end faces, pins, key, fibre type, lane map, length and test requirements.
