tde is the first network expert in Europe to integrate the MMC connector from US Conec into its successful tML system platform, thereby doubling the packing density of its cabling systems.

Up to 4,608 fibers on one height unit: network expert optimises packing density, performance and migration options of the tML system platform 

First cabling platform with MMC connectors in the rear and patch area: tde presents tML 24+

Dortmund/Germany, February 2, 2024. tde – trans data elektronik GmbH continues to drive forward its technological leadership in the modular cabling system field for maximum packing efficiency, investment security and simple migration currently up to 800 G and more: tde is the first network expert in Europe to integrate the MMC connector from US Conec into its successful tML system platform, thereby doubling the packing density of its cabling systems. Simultaneously, tde is presenting the new tML24+, an innovative solution based on the integration of the highly compact 24-fiber MMC multi-fiber connector in the rear area. tde also provides tML modules with MMC for the patch area: One module accommodates 24 MMC adapters at the front, each with 12, 16 or 24-fiber MMC connectors and therefore up to 4,608 fibers modularly on one height unit. Thanks to its APC angle-polished convex surface, even in the multimode version, the MMC offers improved performance in terms of insertion loss and return loss. Customers benefit from migration and investment-proof high-density applications currently up to 800 G and higher. 

Limited and costly space in data centres should be used in the best possible way. tde has been working on this for many years – combining forces with strategic technology partners such as US Conec. The result of the latest co-operation: With the new tML24+, tde is the first provider in Europe to offer customers a modular cabling system based entirely on the MMC connector. “We rely on the MMC in the rear area – this is new and unique on the market,” says André Engel, Managing Director of tde, and continues: “With its design and performance, the MMC is predestined for high-density applications with improved return loss and insertion loss values. In combination with our modular tML24 system platform, we can once again significantly increase the packing efficiency of data centre cabling and offer customers migration and investment-proof solutions for high-speed applications – now and in the future. This once again demonstrates our role as a technology leader in the multi-fiber technology field.”

New perspectives for high-density applications 
Different from the previous MPO connector, the tML24+ system solution relies on the 24-fiber MMC connector in the rear area: this combines the space-saving TMT ferrule (Tiny MT) with a VSFF connector (Very Small Form Factor) and is therefore only a third of the size of an MPO connector. In addition, the MMC also has better return loss and insertion loss performance. The reason for this is the APC angle-polished convex surface, which the MMC offers in both the single mode and multimode versions. Its optical performance complies with the IEC 61753-1 Class B standard with an improved insertion loss of max. 0.25 dB. The connector has been tested to Telcordia standard GR-1435 and TIA 568 mechanical requirements and fulfils the GR-326 standard.

The tML – tde Modular Link System
tML is a patented, modular cabling system consisting of three key components: the module, trunk cable and rack mount enclosure. The system components are 100 percent manufactured, pre-assembled and tested in Germany. They enable plug-and-play installation on site – especially in data centres, but also in industrial environments – within the shortest possible time. Heart of the system are the rear MPO/MTP or MMC and Telco connectors, which can be used to connect at least six or twelve ports at a time. Depending on the module configuration, transmission rates of up to 800 G are currently possible. The fiber optic and TP modules can be used together in a module carrier with a very high port density.
