The NVIDIA MFP7E20-N015 is a specialized 15-meter passive fiber splitter cable designed for high-density data center deployments. Unlike standard cables, this is a breakout or fanout cable with a 1:2 splitter configuration. It features one MPO-12/APC connector on the trunk end (for connecting to a switch's 400G port) and two MPO-12/APC connectors on the branch ends (for connecting to two servers). It utilizes 50/125μm OM4 multimode fibers in a Type-B crossover topology, enabling efficient distribution of a single 400G bandwidth into two 200G streams, making it an ideal data center interconnect solution for connecting high-speed switches to multiple servers.

• Configuration: 1x MPO-12/APC (Trunk) to 2x MPO-12/APC (Branch) breakout.
• Cable Length: 15 meters, OM4 50/125μm multimode fiber.
• Speed Mapping: Splits a single 400Gb/s (4x100G lanes) link into two 200Gb/s (2x100G lanes) links.
• Cable Jacket: Flexible, round Aqua-colored LSZH-OFNR jacket.
• Optical Performance: Low insertion loss (≤ 0.356 dB), High return loss (≥ 35 dB).
• Protocol Support: InfiniBand NDR/HDR 400/200GbE NVLink

This advanced breakout solution is engineered to meet rigorous industry standards for performance and reliability in demanding environments.

• Fiber Standard: OM4 Multimode Fiber (IEC 60793-2-10) for high bandwidth and extended reach.
• Connector Standard: MPO per IEC 61754-7 and ANSI/TIA-604-5.
• Polish Technology: Angled Physical Contact (APC) is critical for maintaining low optical return loss in splitter applications.
• Splitter Technology: Passive optical splitter within the cable assembly, no external power required.
• Safety & Compliance: Complies with Telcordia GR-1435, Laser Class 1 (IEC 60825), with CB, cTUVus, CE certifications.

This MPO breakout cable operates on a passive optical splitting principle. The trunk end (single MPO-12) connects to an 800Gb/s twin-port OSFP transceiver (operating in 400G mode) or a single 400G port. Inside the cable assembly, the four transmit (Tx) optical lanes from the switch port are passively divided: Lanes 1 & 2 are routed to the first branch connector for Server A, and Lanes 3 & 4 are routed to the second branch connector for Server B. The receive (Rx) path works inversely. This creates two independent full-duplex 200Gb/s links (each utilizing 2 fibers for Tx and 2 for Rx) from the original 400Gb/s port. The internal crossover (Type-B) and APC polish ensure correct lane alignment and minimal signal degradation across both split paths, a key requirement for a reliable 400G to 200G cable.

• High-Density Server Connectivity: Connecting a single 400G switch port to two servers equipped with ConnectX-7 200G or BlueField-3 adapters, effectively doubling connection density.
• Cost-Optimized AI/ML Clusters: Fanning out connections in GPU server clusters where individual nodes require 200G bandwidth but switch port count is limited.
• Storage Server Connectivity: Connecting two storage nodes or JBODs to a single high-speed switch port.
• Top-of-Rack (ToR) Consolidation: Reducing the number of switch ports required per rack, simplifying cabling and reducing switch cost.
• Network Interface Card Deployment: Ideal for deployments utilizing multiple network cards (like the ConnectX-7 series) where port breakout is required.

Other Lengths Available: 3m, 5m, 7m, 10m, 20m, 30m, 50m.

• Density & Cost Optimization: This fiber splitter cable provides a more economical and space-efficient alternative to using multiple switch ports and standard cables for connecting two servers.
• Simplified Cable Management: Reduces cable clutter by replacing two separate cables with one managed breakout solution, improving airflow and organization.
• NVIDIA Validated Performance: Guaranteed compatibility and performance when used within the NVIDIA switch and adapter ecosystem, unlike third-party breakout solutions.
• Passive & Reliable: Contains no active electronics, offering higher reliability and no power consumption compared to active optical splitters.

Q1: What switch and adapter models is the MFP7E20-N015 compatible with?
A: It is designed for NVIDIA switches with OSFP DR8 (400G/NDR) ports and servers equipped with ConnectX-7 or BlueField-3 adapters using OSFP or QSFP112 200G transceivers. Compatibility with specific switch and nic card models should be verified.

Q2: Can I achieve 400G speed on the server side with this cable?
A: No. This is a breakout cable. Each server branch delivers a maximum of 200Gb/s. To get 400G to a single server, use a standard MFP7E10 cable (non-splitter). This fanout cable is for sharing a 400G port between two 200G endpoints.

Q3: Does the splitter cause any signal degradation or latency?
A: The passive optical splitter introduces a minimal, standardized insertion loss (accounted for in the specs). It does not add electronic latency. The overall link performance remains within the budget for reliable 200G operation over the specified distance.

Q4: How do I identify the correct branch for each server?
A: The two branch connectors are labeled "1" and "2". For consistency, it's recommended to document which server is connected to which labeled branch. The mapping of optical lanes is fixed within the cable.

Q5: Can I use this with a QSFP-DD port?
A: This cable uses MPO-12/APC connectors. It is compatible with QSFP-DD ports only if they are populated with an appropriate OSFP-to-QSFP-DD adapter or a transceiver that presents an MPO-12/APC interface. Direct physical connection is not possible.

• Configuration Planning: Ensure your switch port and server adapters support the 400G-to-2x200G breakout mode. Consult switch OS and adapter firmware documentation.
• Connector Compatibility: All connected transceivers must be MPO-12/APC type (green shell). Do not mix with MPO-12/UPC (blue shell) interfaces.
• Bend Radius & Strain Relief: Maintain a minimum bend radius of 30mm. Use proper strain relief, especially at the split point and connector boots, to avoid stress on the fibers.
• Cleaning: Clean all three MPO connectors (one trunk, two branches) and the corresponding transceiver ports with certified optical cleaners before mating.
• Installation Path: Plan the routing path carefully for the 15-meter cable and its two branches to avoid tangling and ensure clean cable management in the rack.
