MPO (Multi-fiber Push On) is a multi-fiber optical connector complying with the international standard IEC 61754-7. Specified by IEEE 802.3ba as the preferred fiber connector for 40G/100G transmission, it is also a recommended interface for data center cabling and building backbone cabling.

Three Core Principles for Data Center Cabling

High Reliability: Implement multi-path redundancy and high-quality cabling infrastructure.
High Density: Deploy compact high-density components to save rack space and improve thermal dissipation.
High Safety: Deliver superior flame retardancy amid densely routed cables.

Advantages of MPO versus Traditional Copper Cabling

Transmission reach for 40G/100G networks: up to 100 m with MPO versus only 7 m for copper cables.
Slimmer outer diameter (3.2 mm vs 7–9 mm), greatly cutting tray and cabinet space occupation.
Plug-and-play deployment with fast field installation; no fusion splicing required and single-person maintainability for superior working efficiency.

Key Merits of MPO Cabling System

Ultra-High Density: A 12-fiber MPO plug shares nearly the same footprint as an RJ45 connector; a 1U patch panel supports up to 72 LC fibers while a 4U variant accommodates 288 fibers.
Consistent Performance: Factory pre-terminated construction eliminates field fusion splices with 100% factory testing; protective boots and pull tabs equipped on both ends.
Rapid Rollout: Three-step installation (mount patch panel, route fiber trunk, plug into transceivers) with no special tools or splicing needed.
Future-Proof Upgrade: Natively compatible with 40G/100G networks to avoid full recabling during hardware upgrades.
Neat Layout & Easy Administration: Over 40% reduction in cable footprint improves heat dissipation and reduces wiring clutter.
