The \u003cem\u003ejacket\u003c\/em\u003e color tells you the fiber type — aqua is OM3\/OM4 — not the endface. Two different things, easy to conflate, and jacket colors 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. 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\u003eAn SR4 module uses four lanes in each direction. NVIDIA's own MFP7E10 multimode 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 an SR4 link needs. Ours terminates all twelve. In an SR4 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\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\/mma4z00-ns400-compatible-400g-osfp-sr4-flat-top-rhs-transceiver-connectx-7\"\u003eMMA4Z00-NS400\u003c\/a\u003e — 400G OSFP SR4, flat-top (ConnectX-7 \/ ConnectX-8 \/ DGX, 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\/mma1z00-ns400-compatible-400g-qsfp112-sr4-transceiver-bluefield-3-connectx-7\"\u003eMMA1Z00-NS400\u003c\/a\u003e — 400G QSFP112 SR4 (ConnectX-7 QSFP112 and BlueField-3, 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\/mma4z00-ns-compatible-800g-osfp-sr8-finned-top-ihs-transceiver-quantum-2\"\u003eMMA4Z00-NS\u003c\/a\u003e — 800G OSFP 2×SR4, twin-port (Quantum-2 \/ Spectrum-4, 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\u003eSingle-mode DR-class modules\u003c\/td\u003e\n\u003ctd\u003eMPO-12\/APC\u003c\/td\u003e\n\u003ctd\u003eUse the \u003cstrong\u003eOS2 single-mode\u003c\/strong\u003e version instead\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eOSFP does not go in a BlueField-3.\u003c\/strong\u003e NVIDIA states that BlueField-3 adapters accept QSFP112 devices only, so a BlueField-3 takes the \u003ca href=\"\/products\/mma1z00-ns400-compatible-400g-qsfp112-sr4-transceiver-bluefield-3-connectx-7\"\u003eMMA1Z00-NS400\u003c\/a\u003e, not the OSFP MMA4Z00-NS400.
