MPO Cabling high-density and high-port count fiber equipment

As networking equipment becomes denser and port counts in the data center increase to several hundred ports, managing cables that are connected to these devices becomes a difficult challenge. Traditionally, conneting cables directly to individual ports on low-port-count equipment was considered manageable. Applying the same principle to high-density and high-port-count equipment makes the task more tedious, and it is nearly impossible to add or remove cables that are connected directly to the equipment ports.

Using fiber cable assemblies that have a single connector at one end of the cable and multipe duplex breakout cables at the other end is an alternative to alleviate cable management. Multifiber Push-On (MPO) cable assemblies can achieve these goals. The idea is to pre-connect the high-density and high-port-count Lucent Connector(LC) equipment with and MPO to LC Breakout cable (shown in Figure 6-1) to dedicated MPO modules with a dedicated patch panel. After the panel is fully cabled, this patch panel functions as through it were “remove” ports for the equipment. These dedicated patch panels ideally should be above the equipment whose cabling they handle for easier access to overhead cabling. Using this strategy drastically reduces equipment cabling clutter and improves cable mangament.

As an example, the MPO module that is shown in Figure 6-1 is housed in a modular patch panel that is installed above a Fiber Channel director switch at the EDA. MPO trunk cables are used to link this patch panel to another moudular patch panel at the HDA. The patch panel at the HDA converts the MPO interface back to the LC interfaces by using MPO cassette. MPO trunk cables an accommodate up to 72 individual fibers in one assembly, providing 36 duplex connetions.

Choose the fire-rated plenum type. These cables might not be as flexible as the patch cords because they are meant for fairly static placements, for example, between the EDA and the HDA. For fiber, high density involving 24-strand to 96-strand cables is adequate. Fiber breakout cables provide more protection, but add to the diameter of the overall cable bundle. For fiber, MPO fiber trunk cable(up to 72 fiber strands can be housed in one MPO connetion) can be installed if you are using MPO style cabling.

Fiberstore offers a broad selection of high density connectivity and high capacity cable management. Here are just a few:

High Density MPO Cassettes

Using high density angled panels, this system allows users to mix and match fiber copper and fiber snap in cassettes. The MPO cassette is available in 1RU and 4RU configurations, support up to 48 copper ports or duplex fiber channels per 1RU (192 copper or 192 fiber in a 4RU space).

About Fiber Optic Pigtail

Fiber optic pigtails are recommended or sometimes required when there is a need to make a transition from thin buffered fibers (250-900um), typical for distribution cables and not suitable for direct optical fiber connector termination, to cross-connection or equipment connection point. Pigtails mechanically or fusion connected to the distribution cable fibers simplify cabling system installation and servicing significantly. Fiber optic pigtails are used to achieve accurate mounting for precision alignment of fiber optical components. The fiber pigtails are usually used with fiber optic management equipment like ODF, splice closures and cross cabinets.

Fiber pigtail is piece of fiber optic cable with only one fiber optic connector on one side of the cable while leave the other side no connectors, so that the connector side can link to the equipment and the other side can be melted with optical fiber cables. Commonly used fiber optic pigtail types are SC, ST, FC, LC MT-RJ, SC/APC, FC/APC, E2000 fiber optic connectors. They are single mode types and multimode types.

Fiber optic pigtails the typical use is to link the fiber optic cable with fiber optic equipment, the fiber optic pigtail with connector side is used to link the equipment, while the other side of the pigtail is melted together with the fiber cable, by melting together the fiber glasses, it can reach a minimum insertion loss. Common types of fiber optic pigtails are usually with 0.9mm fiber cable diameter, and usually installed inside ODF unit. Most commonly used types are SC fiber optic pigtail, ST fiber optic pigtail,FC fiber optic pigail, LC fiber optic pigtail ,MT-RJ fiber optic pigtail,SC/APC fiber optic pigtail, FC/APC fiber optic pigtail and E2000 fiber optic pigtail.

Something About MPO MTP Fiber Cable

MPO/MTP stands for “Multiple-Fiber Push-On/Pull-off”. The purpose of MPO/MTP technology is that you can pull just one single cable with 8 (for example) fibers. So instead of patching 8 separate fiber cables, you only need to patch one cable with one connector. MPO/MTP Fiber Cable is used in various applications for all networking and device needs like 100 Gigabit modules.

MTP/MPO is usually used in ribbon fiber optic patch cords or ribbon fan-out multi-fiber assemblies. The ribbon fiber optic cables feature multi-fiberglass inside each single jacket, and MTP/MPO also multi a multi-fiberglass core inside each single connector. That is to say, there are several fiberglass connections in each single MTP/MPO fiber optic patch cord, for example, 4 fibers, 8 fibers, 12 fibers, etc. Typical MTP/MPO fiber optic patch cord assemblies like MTP/MPO to 8 LC, MTP/MPO to 12 SC, etc. MTP/MPO fiber optic patch cords are also available in single mode and multimode, like UPC and APC Polish.

MTP fiber optic patch cable has MTP fiber optic connectors which are upgraded versions of the former MPO. MTP has better mechanical and optic fiber performance compared with MPO. Both the MTP and MPO series cables are multi-fiber connectors. There are many fiber optic channels in each single connector. Because of such multi-fiber features, these connectors need to be used with multi-fiber cables, especially ribbon multi-fiber optic cables.

MTP and MPO cables are available in female-to-female or a male to male and male-to-female configurations. The male version has MTP pins. These can be made with 12-fiber MTP connectors, 24-fiber MTP connectors, and 48-fiber MTP connector variations. We use MTP fiber optic connectors for all of our MTP and MPO terminations so that the highest performance is accomplished. Many additional options and combinations are available. All multi-fiber optic cables are customizable.

To have a better understanding of MTP, I will introduce you to some MTP terminology as follows:

About MTP Trunks

The MTP Trunk cable is designed for Data Center Applications. This cable is a round cable with an outer diameter of 3,0 mm or 4,5 mm (with two jackets on both sides). The connector where this cable is terminated is the so-called MTP connector (female).

About MTP Fiber Optic Cassette
The MTP cassette is nothing more than a basic case that splits out MTP to SC/LC connectors, which is available for 12 SC/LC connectors and 24 connectors.

About MTP fanouts

MTP fanout cables are cables that are multiple cables that are bundled within the same jacket. This is also often referred to as a Breakout cable.

About Direct Splits (MTP to LC or MTP to SC cables)

MTP Direct Split cables are cables with the fanout made directly in the MTP connector. These are designed for high-density Data Center applications to plug into MTP cassettes and/or MTP patch panels.

FS provides many fiber optic products such as fiber patch cables, Armored Cables, Industrial Cables, and more.
