The Development of MTP Cables

With better performance and lower network infrastructure costs, MTP cables replace cables terminated with SC and LC connectors in high-density data centers and enterprise networks. From the increase in the number of fibers to the release of the lower insertion loss version of MTP Elite, MTP cables are constantly evolving. In the future, MTP cables will continue to advance to overcome challenges in connector gender and polarity management.

What Are the Differences between MTP® and MPO Cables?

The key differences between MTP® and MPO cables come in their connectors. As for their connectors' mechanical design, MTP® and MPO cables are different in terms of pin clamp, floating ferrule, and housing removability. Moreover, these two cables' optical performances, such as insertion loss and reliability, also differ.

MTP®/MPO Cabling in Spine-Leaf Architecture

MTP/MPO cabling solves the cable installation and management challenges of spine-leaf architecture and reduces time and labor costs. In particular, MTP/MPO optic fiber cables support fewer connections and feature lower insertion loss, which increases redundant Ethernet cross connections and contributes to the deployment of spine-leaf architecture.

What Are MTP/MPO Conversion Cables and Their Applications?

MTP/MPO conversion cables have the same form as MTP/MPO breakout cables but are terminated with MTP/MPO connectors on both ends, especially fitting for high-density cabling. MTP/MPO conversion cables are used for network migration, such as 10G-40G, 40G-40G, 40G-100G, and 40G-120G direct connections.
