A UPC connector is flat. They cannot mate. Put them together and you get an air gap, an unusable return loss figure, and a link that either never comes up or comes up and drifts.\u003c\/p\u003e\n\u003cp\u003eThe 100G (4×25G NRZ) and 200G (4×50G PAM4) generations were overwhelmingly \u003cstrong\u003eUPC\u003c\/strong\u003e. The NDR and XDR generations moved to \u003cstrong\u003eAPC\u003c\/strong\u003e. A customer upgrading an existing fabric does not carry their patch cords forward. This is the most common ordering mistake in an upgrade, and most supplier pages never mention it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow to tell at a glance:\u003c\/strong\u003e a green connector housing means APC — NVIDIA's own module documentation describes the MPO-12\/APC interface as having a green plastic shell. The \u003cem\u003ejacket\u003c\/em\u003e color tells you the fiber type — yellow is single-mode — not the endface. Two different things, and easy to conflate. Jacket colors also vary between manufacturers; the connector housing is the reliable answer.\u003c\/p\u003e\n\n\u003ch2\u003eKey orientation: key-up to key-down\u003c\/h2\u003e\n\u003cp\u003eThe industry shorthand \"Type B means key-up to key-up\" is a \u003cstrong\u003eUPC\u003c\/strong\u003e rule, and it does not transfer to APC. Two 8° angled endfaces have to be complementary to seat, so an APC Type B assembly mates \u003cstrong\u003ekey-up to key-down\u003c\/strong\u003e — Modified Method B, a Type B cable through Type A (key-up\/key-down) adapters.\u003c\/p\u003e\n\u003cp\u003eThis cable is built key-up to key-down, confirmed in writing by the manufacturer. It is worth checking whatever else you are buying: it is not unusual to find a part listed as APC and \"female key-up to female key-up\" on the same page, which cannot physically mate.\u003c\/p\u003e\n\n\u003ch2\u003eFully terminated 12-fiber — and why that is a feature\u003c\/h2\u003e\n\u003cp\u003eAll twelve positions are terminated in a Type B crossover: position 1 lands on position 12, 2 on 11, and so on across the connector.\u003c\/p\u003e\n\u003cp\u003eA DR4 module uses four lanes in each direction. NVIDIA's own MFP7E30 single-mode cable is built with \u003cstrong\u003eeight\u003c\/strong\u003e fibers populated — positions 1–4 and 9–12, with 5–8 left unconnected — because that is all a DR4 link needs. Ours terminates all twelve. In a DR4 link the two are interchangeable: the module's four transmit positions land on the far end's four receive positions either way, and the extra pairs simply carry no traffic.\u003c\/p\u003e\n\u003cp\u003eThe difference shows up later. A fully terminated assembly can be re-tested end to end, can carry a different lane map if you repurpose it, and does not leave you guessing which positions were populated when a link goes marginal two years from now.\u003c\/p\u003e\n\n\u003ch2\u003eSingle-mode is not a speed bump\u003c\/h2\u003e\n\u003cp\u003eThe DR-class generation moved from SR\/multimode to DR\/single-mode. That is a change to your fiber plant, not just a faster module. \u003cstrong\u003eA multimode cable will not substitute for this one regardless of endface\u003c\/strong\u003e, and an OM4 cable in a DR4 port fails differently from an APC\/UPC mismatch — it will look like a loss problem rather than a mating problem, and you will spend an afternoon on it.\u003c\/p\u003e\n\n\u003ch2\u003eWhich one do I need?\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eModule\u003c\/th\u003e\n\u003cth\u003ePorts\u003c\/th\u003e\n\u003cth\u003eCable\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003ca href=\"\/products\/mms4x00-ns400-compatible-400g-osfp-dr4-flat-top-rhs-transceiver-connectx-7\"\u003eMMS4X00-NS400\u003c\/a\u003e — 400G OSFP DR4, flat-top (NIC side)\u003c\/td\u003e\n\u003ctd\u003e1× MPO-12\/APC\u003c\/td\u003e\n\u003ctd\u003e\n\u003cstrong\u003eThis cable\u003c\/strong\u003e — one per module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003ca href=\"\/products\/mms4x00-nm-compatible-800g-osfp-2xdr4-twin-port-transceiver-quantum-2\"\u003eMMS4X00-NM\u003c\/a\u003e — 800G OSFP 2×DR4, twin-port (switch side)\u003c\/td\u003e\n\u003ctd\u003e2× MPO-12\/APC\u003c\/td\u003e\n\u003ctd\u003e\n\u003cstrong\u003eThis cable\u003c\/strong\u003e — two per module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMultimode SR4 \/ SR8 modules\u003c\/td\u003e\n\u003ctd\u003eMPO-12\/APC\u003c\/td\u003e\n\u003ctd\u003eUse the \u003ca href=\"\/products\/mpo-12-apc-om4-multimode-fiber-patch-cord-type-b-female-unpinned-low-loss-for-nvidia-ndr-400g-800g-optics\"\u003eOM4 multimode\u003c\/a\u003e version instead\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eTwin-port rule:\u003c\/strong\u003e both ports on a twin-port module must run the same fiber type.
