![]() The latest 16-fiber cables are especially designed for short-reach 400G cabling in hyperscale data centers.Ĩ-fiber MTP®/MPO cable systems can transmit the same data rates as 12-fiber cables with lower cost and insertion loss, making them more cost-effective.ġ2-fiber MTP®/MPO cables are the earliest developed and most commonly used solution in 10G-40G, 40G-100G connections. MTP®/MPO cable types with different cores are classified into 8/12/24 cores, usually used for 40G/100G. And now, ANSI/TIA-568.3-E introduced two new universal polarity methods: U1 and U2, which can streamline fiber cabling installations and maintenance.įigure 5: 12-Fiber MTP®/MPO Cable Polarity. Read the white paper Understanding MTP® /MPO Cable Polarity for more information about common 8/12/24-fiber MTP®/MPO cable polarity and connectivity methods. The cables of the three MTP®/MPO connector types have different structures. The TIA 568 standard defines three connection methods to ensure the correct polarity of the optical path, called Type A, Type B, and Type C. Due to the special design of MTP®/MPO connectors, polarity issues must be addressed in high-density MTP®/MPO cabling systems. MTP®/MPO cable types by polarity refer to the difference between the optical transmitters and receivers at both ends of the fiber link. They are especially ideal for 10G-40G, 40G-40G, 40G-100G, 40G-120G connections, which eliminate fiber wasting and largely increase the flexibility of MTP®/MPO cabling system.įigure 4: 40G-120G Direct Connection with MTP®/MPO Conversion Cable. Specifically, commonly-used ones are 24-fiber to 2×12-fiber, 24-fiber to 3×8-fiber, 2×12-fiber to 3×8-fiber MTP®/MPO conversion cables. They are terminated with MTP®/MPO connectors on both ends. MTP®/MPO conversion cables have the same fanout design as MTP®/MPO breakout cables but differ in fiber counts and types. Typically, these breakout cables are ideal for short-range 10G-40G and 25G-100G direct connections or for connecting backbone assemblies to a rack system in the high-density backbone cabling.įigure 3: 25G-100G Direct Connection with MTP®/MPO Breakout Cable. harness cables or fanout cables) are terminated with a female/male MTP®/MPO connector on one end and 4/6/8/12 duplex LC/FC/SC/ST connectors on the other end, such as 8-fiber MTP®/MPO to 4 LC harness cables and 12-fiber MTP®/MPO to 6 LC harness cables. ![]() Typically, these multi-fiber MTP®/MPO trunk cables are ideal for creating a structured cabling system, including backbone and horizontal interconnections such as 40G-40G and 100G-100G direct connections.įigure 2: 40G-40G Direct Connection with MTP®/MPO Trunk Cable. MTP®/MPO trunk cables are terminated with an MTP®/MPO connector (female/male) on both ends, which are available in 8-144 fiber counts for users’ choices. Three MTP®/MPO cable types, such as trunk cables, MTP®/MPO breakout cables, and MTP®/MPO conversion cables, are well suited for high-density cabling networks, providing better network capacity and flexibility. ![]() Various MTP®/MPO cables are available for different application environments and requirements. MTP®/MPO cable types are dominated by 5 performances including function, polarity, fiber count, fiber mode and jacket rating. MTP®/MPO connectors greatly increase cable density and save circuit card and rack space, which are well suited for current 40G/100G cabling and future network speed upgrades.Īpplications of MTP®/MPO Cable Types in 5 Performances MTP®/MPO connectors have a female type (without pins) or a male one (with pins). MTP®/MPO cables are composed of MTP®/MPO connectors and optical fibers. ![]() And there are three MTP®/MPO cable types: MTP®/MPO Trunk Cables, MTP®/MPO Harness Cables and MTP®/MPO Conversion Cables. They look alike and are completely compatible and intermateable. MTP® is a registered trademark of US Conec Ltd., which is an advanced version of MPO, with better mechanical and optical performance. MPO (Multi-Fiber Push-on) is the first generation of clip clamping multi-core optical fiber connectors. This article is going to introduce different MTP®/MPO cable types and their applications. To solve this problem, MTP®/MPO cables accommodating more fibers in one multi-fiber MTP®/MPO connector came into the market, which proves to be practical solutions for 40G/100G/400G/800G high-density cabling in data centers. With ever-greater bandwidths and network connections to deal with in data centers, conventional dual-fiber patch cables like LC cables are no longer sufficient to meet the demands. ![]()
