MPO/MTP Fiber Interconnection Products FAQs

The increasing demand on today's higher fiber counts has exploded the development of multi-fiber technology. FiberStore is one of the main manufacturing of MPO/MTP fiber patch cable and cassettes, and many other MPO/MTP fiber interconnection products, which engineers unique MTP solutions using 12, 24, 48 and even 72 fiber MTP ferrules.
What is an MTP Trunk Cable?
An MTP trunk cable provides 12 to 144 fibre connectivity, by using 12-fibre push/pull optical connectors, it minimized errors and reduced spaces. The MTP trunk cable allows for lower bend radii and smaller slack loops. It enables up to 6x the cable tray capacity over traditional bulkier cabling solutions, saving up to 65 percent space. MPO trunk cable features round furcation legs that provide easy routing and improved storage. With the small profile furcation plug, it allows stress free cable mounting, leaves no legs outside the housing and shipped with strain-relief mounting cradles.
What is MTP Extender/MTP Extension Trunk?
The MTP extension Trunk extend subsets of links from zone distribution into equipment zones, which feature pinned (male) MTP connector on one end and non-pinned (female) MTP connectors on the other. It pinned MTP side mates with trunks via MTP connector panels, while not pinned MTP side plugs into modules or harnesses.
What is MTP couplers?
MTP couplers are simple plastic rectangles that hold two MTP connectors together. One cable going into an MTP coupler needs to have a male connector. The other cable must have a female connector. MTP couplers can be either key-up to key-up, or key-up to key-down. MTP cable has a clip on the top of the connector. On a key-up to key-up coupler, the clips are pointed in the same direction on both of the cables. On a key-up to key-down coupler. On a key-up to key-down coupler, the clips are on opposite sides. This also affects the polarity of the signal. Key-up to key-up couplers invert polarity. Key-up to key-down couplers retain the original polarity. This was initially counter-intuitive to me. It made sense once I thought about it though.
What is MTP harness?
An MTP harness breaks out 12 fiber MTP terminations into LC duplex connectors. It connects to trunks through a pinned MTP connector plug into dual fiber electronics ports with LC uniboot duplex connectors. It is occupying less space than 6 duplex jumpers improve airflow for cooling efficiency. By easing handling of cable connections on high-fibre count SAN directors and switch blades, it enables higher density in equipment patch panels. MTP harnesses are available in two lengths: short harness legs for minimal cable slack and long harness legs for mounting flexibility within a cabinet.

Types Of Fiber Patch Cables - Ingellen

Fiber Patch Cable is also called fiber jumper or fiber patch cord. Specifically, it is like joints used to join two kinds of optic cables or to make a third connection out. Fiber patch cable is mainly used in computer work station to outlet and fiber optic patch panels or optical cross connect distribution center. Choosing the right fiber optic patch cable means the compatibility of the patch cables with the original cable. It requires the rate of data transfer, the optic fiber mode, termination types, etc. must coincident with the original cables, otherwise, there will cause a delay or total information loss in the communication.?Know the different type of fiber optic patch cables is essential to choosing the right fiber patch cord for use. Next we will pay a priority to introducing the types of fiber patch cables:

Generally, fiber patch cables are categorized into different groups based on optical fiber mode, fiber cable type, termination types, connector polishing styles and fiber cable sizes. To specify this introduction, I will bring in fiber patch cable types from Ingellen.com for your reference.

According to Fiber Optic Mode
Single mode
Single mode fiber patch cables use 9/125 micron bulk single mode cable and single mode connectors at both ends. SM 9/125 Fiber Patch Cable from Ingellen is a typical single mode fiber patch cable. Jacket color of this kind of patch cable is usually yellow.
Multimode
Multimode fiber patch cables use 62.5/125 micron or 50/125 micron cable and are terminated with multimode optic connectors at both ends. OM1 62.5/125 Fiber Patch Cable, OM2 50/125 Fiber Patch Cable of Ingellen are two widely used multimode fiber patch cable. OM2 50/125 multimode fiber patch cables offer a lower insertion loss than OM1 62.5/125 fiber patch cords. The cable jacket is usually orange.

10G Multimode
10G fiber optic patch cables are specially designed 50/125 micron fiber optimized for 850nm VCSEL laser based 10Gig Ethernet. 10G fiber patch cable is rated for distances up to 300 meters using 850nm Vertical Cavity Surface Emitting Lasers (VCSEL). Ingellen provides 10G OM3 fiber patch cable that could work well with both VCSEL laser and LED sources and all of them are 100% optically tested for maximum performance. The cable jacket of this type is usually aqua.

According to the Fiber Cable Type
Simplex fiber patch cable
Simplex fiber patch cable means the patch cord has one single fiber and connector on each end. Ingellen fiber optic patch cable has simplex type for OM2 50/125, OM1 62.5/125 and 10G OM3 fiber patch cable.

Duplex fiber patch cable
Duplex fiber patch cable has two fibers and two connectors on each end. Just like Ingellen 10G OM3 Duplex Patch Cable, OM1 62.5/125 Duplex Patch Cable, OM2 50/125 Duplex Patch Cable and Zipcord Duplex Optical Fiber Patch Cable. Each fiber is marked "A" or "B" or different colored connector boots are used to mark polarity.

Ribbon fan-out cable assembly
For ribbon fan-out cable assembly, one end is ribbon fiber with multi fibers and one ribbon fiber connector such as MTP connector (12 fibers), the other end is multi simplex fiber cables with connectors such as ST, SC, LC, etc.

According to the Termination Types
Same connector types
Same connect type means the fiber optic connector on both end is same. Such as ST, SC, LC, FC, MU etc.
Hybrid connector types
Hybrid connector type means the fiber optic connector on each end of the fiber patch cable is different to each other. That is in one end it can be FC, the other end could be ST, SC, or LC etc. Just like FC/ST 10G OM3 Duplex Patch Cable, FC/SC 10G OM3 Duplex Patch Cable, FC/LC 10G OM3 Duplex Patch Cable.

According to Connector Polishing Styles
Fiber optic connectors are designed and polished to different shapes to minimize back reflection. This is particularly important in single mode applications. Typical back reflection grades are - 30dB, -40dB, -50dB and -60dB.
Ingellen provides Tight Buffer Optical Fiber Patch Cable, Loose Tube Optical Fiber Patch Cable and Zipcord Duplex Optical Fiber Patch Cable with different fiber cable jacketsize for your particular application.
