MTP Trunks and Breakouts for 10G to 40G Migration

 

With the rapid development of datacom, 10Gbps is no longer enough for massive data transmission. Many data center managers set their sights on 10G to 40G migration. However, it is not possible to upgrade all 10G equipment in the cabling system because of the high cost. Therefore, finding a cost-effective solution for the migration has become a hotspot. We know that MTP cable gains great popularity among data center managers since it can provide fast installation, high density and high performance cabling for data centers. By using MTP trunk cable and MTP breakout cable respectively, there are two solutions for 10G to 40G migration. And this article is going to share these two solutions with you: MTP trunks and MTP breakouts.

 

Overview of MTP Trunk Cable and MTP Breakout Cable

Before we come to the migration solutions, let’s have a brief overview of MTP trunk cable and MTP breakout cable. MTP trunk cable, terminated with MTP connectors at both ends, can create the permanent fiber links between panels in a structured environment. It is typically used as backbone or horizontal cable interconnections. With efficient plug and play architecture, MTP trunk cable can greatly reduce the installation and maintenance costs. In networking applications, 12-fiber and 24-fiber MTP trunk cables are commonly used: 12-fiber MTP trunk cable is normally for 40G Ethernet network, while 24-fiber MTP trunk cable is normally for 100G Ethernet network.Here is a figure of MTO trunk cables for you.

 

MTP breakout cable, also named MTP fanout cable or MTP harness cable, is terminated with a male/female MTP connector on one side and several duplex LC/SC connectors on the other side, providing a transmission from multi-fiber cables to individual fibers or duplex connectors. It is typically used to connect equipment in racks to MTP terminated backbone cables. MTP breakout cable is designed for high density applications which require high performance and speedy installation without on-site termination.Here is a figure of MTP breakout cables for you.

 

MTP Trunks for 10G to 40G Migration

For 10G to 40G migration, you can use the MTP trunk cable. Also, MTP fiber patch panel can be used to fulfill the data transmission link. With forty-eight LC duplex adapters on the front and twelve 8-fiber MTP adapters on the rear, the high density 40G QSFP+ breakout patch panel acts as a middleman between 10G to 40G connection. The figure below shows the connectivity method. From the left to the right, four 10G SFP+ transceivers are plugged in the SFP+ interfaces on the switch on one side, then the SFP+ transceivers are connected with the front LC ports of MTP fiber patch panel by LC duplex patch cables. With the use of MTP trunk cable, the rear MTP ports of MTP fiber patch panel are linked with one 40G QSFP+ transceiver. Finally, the whole optical link is accomplished by plugging the 40G QSFP+ transceiver in the QSFP+ interface on the switch on the other side.

 

MTP Breakouts for 10G to 40G Migration

For 10G to 40G migration, using the MTP breakout cable is a simple way. As shown in the following picture, four 10G SFP+ transceivers are plugged in the SFP+ interfaces on the switch on one side, while one 40G QSFP+ transceiver is plugged in the QSFP+ interface on the switch on the other side. Then the MTP to LC breakout cable connects the four 10G SFP+ transceivers with the 40G QSFP+ transceiver. Finally, the data can be transmitted from 10G switch to 40G switch through the MTP to LC breakout cable smoothly.

Common Armored Fiber Optic Cables

  Armored fiber optic cables are often installed in a network for added mechanical protection, as they have extra reinforcing in the cable housing to prevent damage. Two types of armored fiber optic cables exist: interlocking and corrugated. Interlocking armor is an aluminum armor that is helically wrapped around the cable and found in indoor and indoor/outdoor cables. It offers ruggedness and superior crush resistance. Corrugated armor is a coated steel tape folded around the cable longitudinally. It is found in outdoor cables and offers extra mechanical and rodent protection.   The Structure of an Armored Fiber Optic Cable In basic armored fiber cable designs, the outer sleeve provides protection against wind, solvents, and abrasion. This outer sleeve is usually made of plastic such as polyethylene. The next layer between the sleeve and the inner jacket is an armoring layer of materials that are difficult to cut, chew, or bu

what the Differences Between FBT Splitter and PLC Splitter

  In FTTx and PON architectures, optical splitter plays an increasingly significant role to create a variety of point-to-multipoint fiber optic networks. But do you know what is a fiber optic splitter? In fact, a fiber optic splitter is a passive optical device that can split or separate an incident light beam into two or more light beams. Basically, there are two types of fiber splitter classified by their working principle: fused biconical taper splitter (FBT splitter) and planar lightwave circuit splitter (PLC splitter). You may have one question: what’s the difference between them and shall we use FBT or PLC splitter?   What Is FBT Splitter? FBT splitter is based on a traditional technology to weld several fiber together from side of the fiber. Fibers are aligned by heating for a specific location and length. Because the fused fibers are very fragile, they are protected by a glass tube made of epoxy and silica powder. And then a stainless steel tube covers the inner glass tu

Introduction of Optical Fiber Couplers and How Do They Work?

 What are optical fiber couplers? A fiber optic coupler can be defined as an optical component used with one or more input fibers and several output fibers in fiber optic systems. A coupler essentially puts two or more cores of fibers together to connect. The simple coupler is the fused fiber 2x2 coupler. Couplers are used as multiplexers that are resistant to certain wavelengths. A fiber output depends on the wavelength of light and the frequency of polarization. The fiber refractive index also plays a significant role in the performance. Let’s checkout how do optic couplers work to understand this better. How do fiber optic couplers work? Either fiber optic couplers separate optical signals into multiple paths or combine multiple signals in one direction. Optical signals are more complicated than electrical signals, making it more difficult to design optical couplers than their electrical copy. Unlike electrical currents, the optical signal consists of a stream of signal carriers, in
