12 Fiber MPO to MPO Trunk Cable – OS2/OM3/OM4/OM5, Polarity A/B/C, Custom Length

Product Overview

The 12-Fiber MPO/MTP® Trunk Cable is a highly versatile, customizable cabling solution designed to meet the exact specifications of your network architecture. Whether you are building a Singlemode (OS2) backbone for long-haul transmission or a Multimode (OM3/OM4/OM5) high-speed data center link, this configurable assembly delivers precision performance. It consolidates 12 optical fibers into a single, durable cable, significantly reducing congestion in cable trays and racks.

Engineered by MeFiber for flexibility and reliability, this trunk cable can be tailored to any length and polarity requirement. Available with standard MPO or high-performance MPO/MTP® connectors, it supports the full range of Ethernet speeds from 10G to 400G. With options for Type A, Type B, and Type C polarity, you can ensure perfect signal alignment for any equipment configuration. Factory termination guarantees low insertion loss, providing a plug-and-play solution that outperforms field-terminated cabling.

Key Features

• Wide Fiber Selection: Available in Singlemode (OS2) and Multimode (OM3, OM4, OM5) to match your bandwidth and distance needs.
• Custom Polarity Options: Choose from Type A (Straight), Type B (Crossover), or Type C (Pairs Flipped) to match your transceiver or patch panel requirements.
• High-Density Connectivity: 12-fiber interface supports standard 40GBASE-SR4 and 100GBASE-SR4 applications.
• Premium Jacket Options: Standard LSZH (Low Smoke Zero Halogen) or Plenum (OFNP) ratings available for safety compliance.
• Scalable Performance: Future-proof your network with OM5 Wideband Multimode Fiber (WBMMF) options for SWDM4 applications.
• 100% Tested: Every MeFiber assembly is optically tested for insertion loss and return loss before shipping.

Applications

This fully customizable trunk cable supports a diverse range of networking scenarios:

• Data Center Backbones: High-density cabling between Main Distribution Areas (MDA) and Zone Distribution Areas (ZDA).
• High-Speed Transceiver Links: Direct connections for 40G QSFP+, 100G QSFP28, and 400G QSFP-DD optics.
• Enterprise Networks: Campus-wide fiber distribution using OS2 Singlemode for extended reach.
• Short-Range Interconnects: Cost-effective OM4 or OM5 rack-to-rack cabling for server clusters.

Specifications

Cross-Platform Compatibility

MeFiber ensures that all our MPO/MTP® assemblies adhere to global standards IEC 61754-7 and TIA-568. This universal compliance allows you to integrate our custom trunks into any existing infrastructure. Whether you are using Cisco, Arista, Juniper, Dell, or HPE equipment, selecting the correct polarity and fiber mode ensures seamless plug-and-play interoperability.

Why Choose MeFiber?

Custom networks require precision. MeFiber utilizes advanced polishing and testing equipment to ensure every connector face meets strict geometry standards. By offering a fully configurable product page, we allow you to specify the exact length, pin configuration, and fiber grade you need, eliminating the waste of “standard length” cables and ensuring your critical data paths are optimized for minimal signal loss.

FAQ

1. What is the difference between MPO and MTP®?

MPO (Multi-Fiber Push On) is the generic interface standard defined by the IEC. MTP® is a brand name for a superior MPO connector developed by US Conec. The MTP® connector incorporates design enhancements, such as a floating ferrule and elliptical guide pins, which improve optical performance and longevity. While MPO is standard, MTP® is often recommended for high-performance networks requiring multiple mating cycles.

2. Which polarity should I choose (Type A, B, or C)?

The polarity depends on your application. Type B (Crossover) is the most common for connecting transceivers (like 40G QSFP+) directly. Type A (Straight) is often used when connecting patch panels that perform the signal flip internally. Type C (Pairs Flipped) is generally used for duplex applications broken out from a trunk. Always check your equipment documentation to confirm the required polarity.

3. When should I choose OM5 over OM4?

OM4 is excellent for standard 10G, 40G, and 100G links using parallel optics. OM5 (Lime Green) is designed specifically for Short Wave Division Multiplexing (SWDM). If you plan to run 40G-SWDM4 or 100G-SWDM4 applications (which send multiple wavelengths over a single fiber strand), OM5 offers better support and longer distances than OM4.

4. How do I know if I need Male or Female connectors?

It depends on what you are plugging into. Transceivers always have pins (Male), so you need a Female (Unpinned) cable to plug into them. Patch panels and cassettes vary; if the panel has pins, you need a Female cable. If the panel is unpinned, you need a Male (Pinned) cable to establish alignment.
