NVIDIA MFP7E10-N020 20m MPO12/APC Multimode Cable for 800G
InfiniBand
NVIDIA® Mellanox® Compatible Passive Optical Cable
Product Overview
The NVIDIA MFP7E10-Nxxx series is a passive
MPO‑12/APC‑to‑MPO‑12/APC multimode fiber cable engineered for
short‑reach interconnects in high‑performance data centers. The MFP7E10-N020 (20 meter variant) uses eight active fibers in a Type‑B crossover
topology to enable direct attached optical link without polarity
reversal adapters. With angled physical contact (APC) 8‑degree
polish, back reflections are minimized, ensuring signal integrity
for PAM4 modulation up to 800Gb/s.
Each cable is factory‑tested to Telcordia GR‑1435 and supports
operating temperatures from 0 to 70°C. The aqua LSZH jacket
provides flame retardance while reducing toxic smoke emission,
suitable for high‑density switches and GPU clusters. For 20-meter
links, the cable utilizes cost-effective OM3 fiber with full
performance margin.

- Connector: MPO-12/APC female, green housing, 8° angled polish
- Insertion loss (max): ≤0.358 dB (0.35 + 0.0004 × 20)
- Return loss: ≥35 dB

- Max reach for OM3: 30m (with two patch panels); OM4 recommended beyond 30m
Why MPO‑12/APC?
Angle‑polished connectors suppress back reflection that would
otherwise degrade laser performance in high‑speed transceivers.
Unlike ultra‑polished (UPC) versions, APC allows reliable operation
at 50G PAM4 per lane. The green NVIDIA shell quickly identifies APC
compatibility, preventing mismating with legacy blue‑shell UPC
cables.
Type‑B crossover: Lane 1 at one end connects to lane 12 at the opposite end -- ideal
for 4‑lane Tx/Rx pairing without external crossover cords.
Technology & Signal Integrity
Designed for 800G DR8 / 400G DR4 architectures, each cable contains
8 multimode fibers arranged in a crossed pinout. The 8‑degree APC
interface reduces optical return loss to >35dB, critical for
high baud rate transceivers such as NVIDIA MMA4Z00‑NS (twin‑port
OSFP). The passive design consumes zero power and introduces no
latency, making it ideal for switch‑to‑switch or switch‑to‑DPU
links in NDR InfiniBand fabrics.
Rigorous end‑face geometry testing and IL/RL verification ensure
each cable meets the stringent requirements of modern 800G Ethernet
and NVLink fabric extensions.
Typical Deployments
- Linking twin‑port OSFP 800Gb/s switches (e.g., Quantum-2) to
ConnectX‑7 network adapters across 20‑meter rack spans
- Connecting NVIDIA BlueField‑3 DPUs (QSFP112 or OSFP) to top‑of‑rack
switches in same-row or adjacent-row positions
- Spine‑leaf interconnects in storage servers requiring short‑haul
OM3 links up to 20m
- Multimode backbone within a row of racks (≤30m for OM3)
Compatibility
The MFP7E10‑N020 works with any transceiver or system that accepts
MPO‑12/APC female connectors and expects Type‑B pinout. Verified
compatibility includes:
- NVIDIA MMA4Z00-NS (twin-port OSFP DR8, 800G)
- NVIDIA MMA4Z00-NS400 (single-port OSFP 400G)
- NVIDIA MMA1Z00-NS400 (QSFP112 400G)
- InfiniBand NDR 400G/800G switches and ConnectX‑7 adapters
- Standard 400GbE switches with MPO‑12 APC optical interfaces
Important note: This cable cannot mate with MPO‑12/UPC (ultra polish, blue shell)
connectors. Mixed use will damage ferrule end faces and cause link
failure.

Frequently Asked Questions
Q1: Can MFP7E10-N020 be used for 800G links longer than 30 meters?
A: For distances between 30-50 meters, we recommend the OM4
variants (MFP7E10-N035 to N050). At 20 meters, OM3 provides full
800G performance with margin.
Q2: Is the cable polarity suitable for NVIDIA Quantum‑2 switches?
A: Yes. Type‑B (crossover) is the standard polarity required by
NVIDIA for direct 800G twin‑port OSFP to OSFP connections.
Q3: What is the difference between MFP7E10 and MFP7E20?
A: MFP7E10 is multimode (MMF), MFP7E20 is single‑mode (SMF). For
distances ≤50m, multimode is cost‑effective; beyond 50m, select
MFP7E20 single‑mode cable.
Q4: Do you provide a cleaning kit recommendation?
A: Yes. We suggest using an MPO‑12/APC dry cleaner (e.g.,
CLICK‑Clean or IBC brand) before each mating.
Q5: Is the 20m length guaranteed for 400G and 800G?
A: Yes, the MFP7E10-N020 passes NVIDIA's compliance testing for
800G DR8 and 400G DR4 links within 20m.
Handling Precautions
- Do not remove dust caps until the moment of installation. Contamination is the #1 cause of
link degradation
- Always clean both cable connector and transceiver optical
receptacle using an MPO‑APC specific cleaner
- Do not bend the cable tighter than 30 mm radius, especially near
connectors
- Never mix MPO‑APC (green/slanted) with MPO‑UPC (blue/flat) --
physical damage will occur
- Comply with standard ESD precautions when handling pluggable
transceivers, although the cable itself is passive
