High-density Modular System and Cabling Options

Data center and telecommunications rooms are rapidly outgrowing their footprints to meet increasing network demands. Keeping costs low and getting higher density are always the goals of data center managers. The modular system allows for rapid deployment of high density data center infrastructure as well as improved troubleshooting and re-configuration during moves, adds and changes. This article will talk about the high-density patching solutions and the associated cabling options.

Fiber patch panels offer the highest level of scalability and density. High-density fiber patch panel or enclosure is an ideal solution for installation with space constraints, and available in flat and angled designs. The angled design increases rack density, managing high-density applications in one-fourth the area needed for conventional cable management systems.

  • MTP/MPO Cassettes

There are two types of cassettes—LGX MTP/MPO cassette and HD MTP/MPO cassette. Both the two types provide secure transition between MTP and LC or SC discrete connectors. With LC or SC adapters on the front side and MTP at the rear, they are used to interconnect MTP backbones with LC or SC patching. The MTP cassettes contain factory controlled and tested MTP-LC fanouts to deliver optical performance and reliability. They can be used in 1RU or 3RU 19” multislot chassis.

MTP/MPO cassette

The HD MTP/MPO cassette is more compact than the LGX MTP/MPO cassette. When using with patch panel, up to 5 HD MTP cassettes can be held in a 1RU HD chassis, but for LGX MTP cassette, only 3 cassettes can be held in it as shown in the above picture. Thus, the HD MTP cassette can improve the port density in the same 1RU panel and save more space.

  • Fiber Adapter Panel

Fiber adapter panels snap quickly into the front of the fiber patch panels and enclosures for easy network deployment or moves, adds, and changes. They can house, organize, manage and protect fiber optic cables. For example, a 48 ports 1RU fiber enclosure can be loaded with four 12x MTP fiber adapter panels. It provides a comprehensive line of fiber distribution enclosures that offer a flexible and modular system for managing fiber terminations, connections, and patching in all applications.

Cabling Options for Modular System

High-density modular system features an innovative design allowing for a plug and play pre-terminated system configuration. Cable assemblies can be directly terminated and installed in the cassettes for fast and easy installation.

  • MTP/MPO Trunk Cable

MTP/MPO trunk cables are used to interconnect cassettes, panels or ruggedized MPO fan-outs, spanning MDA, HDA and EDA areas, and to facilitate rapid deployment of high density backbone cabling in data centers and other high fiber environments reducing network installation or reconfiguration. They offer the flexibility in case any decision is made to change the connector style in the patch panels, new cassettes can be installed with the new connector style on the cross-connect side of the patch panel without having to change the connector on the cable trunk.

  • MTP/MPO Harness Cable

MTP/MPO fanout assemblies route multifiber MTP connection into discrete connectors. They are used to directly interconnect MTP cassettes, panels or backbone MTP assemblies with the active equipment, saving costly data center rack space and easing fiber management.


The modular system is the choice to ease future expansion and for quick and easy system re-configuration, which can save space and meet the demand for high-density network infrastructure.
