What Role Does Fiber Optic Patchcord Play in High-density Data Centers

Fiber optic patchcords are widely used in data centers. In recent years, the demand for bandwidth in high-density data center optical fiber transmission systems has shown a high growth trend, so that the use of a new generation of optical fiber cables and optical modules can continue to explore the potential of optical fiber network bandwidth growth. Because the multimode fiber patch cord has a great advantage in terms of cost, it has an absolute advantage in the application of data centers.


Driven by the continuous application and promotion of network media in the cloud computing environment, multimode fiber optic patchcord are also developing continuously. From OM1 to OM2, and from OM3 to OM4, VCSEL laser optimization technology is used, and the demand for bandwidth continues to grow. The introduction of the new category OM4 multimode fiber patch cord standard EIA/TIA492AAAD provides a better transmission method for the wide application of multimode fiber in the future. This article will provide an ideal communication solution for your data centers, servers, network switches, telecom switching centers, and many other embedded application systems that require high-speed data transmission.


In the transmission port connection equipment in 40G/100G data transmission applications, such as QSFP optical modules, no matter how many fibers are used to connect high-density data center fibers, and no matter what type of fibers are connected, they will be directly connected through MTP|MPO cables. Because the channel connection between the 40G/100G data transmission application device and the device needs to form a special mode so that the channels of the transmitting end and the receiving end of the device correspond to each other, thus requiring an MTP|MPO cable to complete the connection.

MTP|MPO cable can provide various applications for all networks and devices that require 100G modules. They adopt the MT series ferrule design of the high-density multimode fiber optic connector system industry, and the MPO/MTP fiber optic patch cords adopt UPC and APC polished end faces, and support both multimode and singlemode applications. With VCSEL laser and LED light source, 10G OM3|OM4 MPO|MTP fiber cables can provide 10Gbps data transmission rate in high bandwidth applications, which are 5 times faster than standard 50um fiber patch cords.

At the same time, multimode MPO|MTP fiber patch cords are also the most common high-density data center fibers. Single-mode MPO|MTP fiber patch cords are mainly used in long-distance data transmission systems. MPO/MTP backbone patch cords are specially designed for data center applications. Generally, single-mode and multi-mode MPO/MTP fiber optic patch cords are designed as round cables with an outer diameter of 3mm or 4.5mm, and the connectors at both ends of the cable are also called MPO/MTP connectors.


At present, MPO/MTP high-density push-pull fiber patch cords are mainly used in three aspects: high-density wiring data centers, fiber-to-the-home, and connection applications with optical splitters, 40G QSFP+ ,100G QSFP28,10g SFP+ and some other optical modules. Today, there are already a series of high-density parallel optical interconnection products that can adapt to optical fiber transmission in modern data centers, such as customized MPO/MTP optical fiber patch cords, multimode optical fiber loopbacks and QSFP+ high-speed cable assemblies.

The development of server virtualization and cloud computing, as well as the development trend of network integration with high-density data center optical fibers, have brought about the development needs of faster and more efficient data center networks. Fiber optic patchcord play a important role in high-density data centers.
