NVIDIA MFP7E20-N015 1:2 Multimode Fiber Splitter Cable

Core Advantages: Utilizes 8 active multimode fibers (50/125µm) in a 1×MPO-12/APC to 2×MPO-12/APC fanout configuration. One end connects to an 800G twin-port OSFP transceiver; the two split ends link to 400G OSFP or QSFP112 network interface cards, delivering 200Gb/s per branch. Type-B crossover wiring, ultra-low insertion loss, and up to 50 meters of reach make it ideal for high-density fiber interconnect in modern data centers.

Key Characteristics

• MPO-12/APC 8° angled-polished end faces minimize back reflection (return loss ≥35 dB), ensuring excellent signal integrity.
• Push-pull latching mechanism enables quick release in high-density racks; flexible round cable jacket with 30 mm minimum bend radius.
• Compliant with Telcordia GR-1435 and IEC 61754-7, built with 50/125 µm multimode fiber (OM3/OM4).
• Type-B “crossover” wiring: transmit fiber on pin 1 aligns with receive fiber on pin 12 at the far end — no extra configuration needed.
• Factory-tested by NVIDIA for guaranteed out-of-box performance, compatible with ConnectX‑7 NICs and BlueField‑3 DPUs.

Technology & Standards

MPO/APC Low-Loss Optical Engine: Precision alignment holes and guide pins, combined with an 8° angled physical contact (APC) finish, keep insertion loss as low as ≤0.35 dB + 0.0004 × L (L in meters). The angled geometry effectively deflects back reflections away from the laser source, preserving signal quality even over 50 m links.

Crossed (Type-B) Topology: Fibers are arranged so that lane 1 (transmit) on the first connector maps to lane 12 (receive) on the opposite connector. This crossover scheme is mandatory for standard transceiver mating and ensures proper Tx–Rx alignment without manual crossover cables.

Working Principle

The cable acts as a passive optical splitter/combiner. At the 800G twin-port OSFP side, the single MPO connector houses four transmit and four receive fibers (total 8 fibers). Internally, these 8 fibers are divided into two groups of four (2 Tx + 2 Rx per branch) and routed to the two MPO connectors at the split ends. Each branch provides a 2-fiber transmit pair and a 2-fiber receive pair, enabling full-duplex 200G PAM4 signaling. Because the fibers are “Type‑B” crossed, the optical signal from transceiver A’s lane 1 automatically lands on transceiver B’s lane 12, completing the link without any electrical processing.

Applications & Typical Deployments

• Interconnecting an 800G twin-port OSFP DR8 transceiver (e.g., NVIDIA MMA4Z00-NS) in a spine switch to two separate 400G OSFP or QSFP112 NICs in compute or storage servers.
• Enabling 200G optical links using only two fibers per direction — ideal for upgrading existing 100G infrastructure.
• High-speed leaf‑spine topologies in AI and cloud data centers, where short‑reach (50 m) multimode connectivity is sufficient.
• NVLink or InfiniBand clusters requiring reliable, low-latency fiber fanout from twin-port modules.

Ordering & Selection Table

*All cables are passive, Type-B crossover, and feature NVIDIA green connector shells (MPO-12/APC).

Why Choose MFP7E20-N015?

• Optimized for 800G Twin-Port OSFP: Unlike straight MPO cables, this splitter cable unlocks the full potential of dual‑rate 800G transceivers by feeding two independent 400G network cards (or one 400G card and one 200G card).
• Superior Signal Quality: The 8° APC polish guarantees return loss >35 dB, significantly better than typical UPC (ultra‑flat) connectors used in older 100G/200G links.
• Future‑Ready for 200G per Lane: With two fibers per direction, it natively supports 200G PAM4 signaling — ready for next‑gen 1.6T deployments.
• Durability & Safety: LSZH jacket reduces toxic emissions in case of fire; Telcordia GR‑1435 qualification ensures long‑term mechanical reliability.

Frequently Asked Questions

Important Precautions

• Compatibility: Only use with transceivers that have MPO‑12/APC receptacles (green shell). Do not force into MPO‑12/UPC (blue) ports — the angle mismatch will damage both connectors.
• Environmental: Operating temperature 0‑70°C; humidity 10‑85% non‑condensing. Avoid liquid exposure.
• ESD Caution: Although the cable itself is not ESD sensitive, the transceivers it plugs into are. Follow ESD grounding practices during installation.
• Bend Radius: Never bend the cable tighter than 30 mm to avoid micro‑cracks and increased attenuation.
• FCC Class A: This product is intended for commercial/industrial use. In a residential environment it may cause radio interference.
