What Are MPO Trunk Cables? A Data Center Guide for Irving, TX

ByExcellent IT Telecom Solutions

If you manage network infrastructure in the Dallas-Fort Worth area, you have likely heard the term MPO trunk cable. But what exactly is it, and why has it become the standard backbone solution for modern data centers? This guide covers everything IT professionals and business owners in Irving, TX need to know.

What Does MPO Stand For?

MPO stands for Multi-fiber Push-On, a fiber optic connector type standardized under IEC 61754-7. It houses multiple fibers inside a single rectangular ferrule. One push-pull motion locks all 12 fibers simultaneously, replacing what would otherwise be six separate duplex LC connections.

What Is an MPO Trunk Cable?

An MPO trunk cable has an MPO connector on both ends with no fan-out legs. It runs point-to-point between two patch panels, transceivers, or switches, carrying all 12 fibers as a single managed unit. Trunk cables form the high-density backbone of structured cabling systems in data centers and equipment rooms.

Key Specifications

  • Fiber count: 12-fiber standard for 40G/100G applications
  • Insertion loss: Elite grade 0.35dB (vs standard 0.5dB)
  • Polarity: Type B (key-up to key-down) is the data center standard
  • Fiber type: OS2 single-mode or OM3/OM4 multimode depending on distance

OS2, OM3, and OM4 Explained

OS2 (yellow, 9/125um): Single-mode fiber for long distances, 1310nm/1550nm wavelength. Best for inter-building runs or distances over 300m.

OM3 (aqua, 50/125um): Multimode fiber, supports 10G to 300m and 100G to 100m at 850nm. Cost-effective for within-datacenter backbone.

OM4 (erika violet, 50/125um): Enhanced multimode, supports 10G to 550m and 100G to 150m. The preferred choice for new high-density DFW data center builds.

Common Applications in DFW Data Centers

MPO trunk cables are deployed for MDA-to-HDA interconnects, top-of-rack switch aggregation runs, pre-terminated cabling systems in colocation facilities, and 40GBASE-SR4/100GBASE-SR4 parallel-optics links. Across Irving, Las Colinas, and the DFW Metroplex, EITS installs MPO trunk infrastructure in enterprise, healthcare, and financial facilities daily.
