Cable management: MTP Modules and Harnesses in Data Center

FacebookTwitterGoogle+LinkedInRedditTumblrShare

Traditional optical cable management such as duplex patch cords and duplex connector assemblies work well in application-specific, low-port-count environments. But as port counts scale upwards and system equipment turnover accelerates, these cable managements become unmanageable and unreliable. Deploying a modular, high-density, MTP-based structured wired cabling system in the data center will significantly increase response to data center moves, adds and changes (MACs). Knowledge of MTP modules and MTP harnesses will be provided in this blog.

Introduction to MTP Modules and Harnesses 
An obvious benefit to deploying a MTP-based optical network is its flexibility to transmit both serial and parallel signals. MTP to duplex connector transition devices such as modules and harnesses are plugged into the MTP trunk assemblies for serial communication. MTP Modules are typically used in lower-portcount break-out applications such as in server cabinets. MTP harnesses provide a significant increase in cabling density and find value in high port count break-out situations such as SAN Directors (see figure below). The built-in modularity of the solution provides flexibility to easily configure and reconfigure the cabling infrastructure to meet current and future networking requirements. MTP harnesses and modules can be exchanged or completely removed from the backbone network to quickly adapt to data center MACs.

MTP Modules in Data Centers
MTP modules typically are placed in a housing located in the cabinet rack unit space. Here the MTP trunk cable is plugged into the back of the module. Duplex patch cords are plugged into the front of the module and routed to system equipment ports. Integrating the MTP modules cabling solution into the data center cabinet can enhance the deployment and operation of the data center cabling infrastructure. As shown in the figure below, integrating the MTP modules into the cabinet vertical manager space maximizes the rack unit space available for data center electronics. MTP modules are moved to the cabinet sides where they snap into brackets placed between the cabinet frame and side panel. Properly engineered solutions will allow MTP modules to be aligned with low-port-count system equipment placed within the cabinet rack unit space to best facilitate patch cord routing.

MTP Harnesses in Data Centers
MTP harnesses are plugged into the backbone MTP trunk assemblies through an MTP adapter panel. The MTP adapter panel is placed in a housing that is also typically located in the cabinet rack unit space. MTP to LC 12-fiber break-out harnesses plug into the front of the adapter panels and are routed over to the director line cards where the LC duplex ends are plugged into the line card ports (see figure below). These MTP harnesses are pre-engineered to a precise length with strict tolerances to minimize slack, while a small outside diameter allows for easy routing without preferential bend concerns. With a pre-engineered cabling management, not only is installation simplified, but the time required for SAN design and documentation is greatly reduced with port mapping architecture inherent to the design.

How to Choose the Right Rack Mount Fiber Enclosure?

Fiber enclosure can provide easy-to-manage cabling environments and strong protection for fiber optic cables. Since more and more cables used in today’s data centers, high-density cable management tools also become more popular and essential than before. However, there are so many fiber enclosure manufacturers and suppliers, and the rack mount fiber enclosures supplied therefore available in different sizes and applications. How to choose the rack mount fiber enclosures for your network?

Rack Mount Enclosures Configurations
The rack mount enclosure is generally made for standard 19 inch rack mounting. Depending on the number of connections required, they are available in one or more rack units (RU) height configurations, such as 1RU, 2RU or 4RU, etc. See the picture below, you should choose the most proper one depending on space and port requirement of your network.

Rack Mount Enclosures Mount Types
1RU rack mount fiber enclosures are the most commonly used size in data center server racks cable management. For convenient installation and cable management, there are cover removable, slide-out and swing-out three mount types fiber enclosures to choose from. The cover removable type is an early type of fiber enclosures. If your budget is sufficient, I will recommend you to use the slide-out type or swing-out type though they are more expensive than the cover removable type. But you may get more benefits during installation and maintenance, as they respectively feature a convenient slide-out support tray and an integrated swing-out tray so that you don’t need to remove the whole enclosure from the rack to gain internal access.

Three Kinds of Polarity Reversal Methods of LC Uniboot Patch Cords

As the networking environment of today becomes increasingly dependent on high-speed and high-density solutions, effective cable management is a real problem. The challenge is how to manage more cables in a smaller amount of space. The LC uniboot patch cord utilises a special “round duplex” cable that allows duplex transmission within a single 2.4mm or 3.0mm cable, which reduces cable management space by up to 70% comparing to standard LC patch cords. Besides, it has a unique polarity reversal design allows the fiber polarity to be easily switched without the use of any tools. In today’s LC uniboot patch cords market, there are usually three methods to reverse the polarity.

Method One
1. Open connector top.

11
2. Switch the polarity.

22
3. Close connector top.

33

Method Two
1. Locate trigger housing on LC uniboot connector and pull towards the boot.

1
2. Open trigger housing is resting on the boot turn each LC connector to the outside 180 degrees one at a time.

888
3. Complete the polarity reversal by turning the resting trigger housing 180 degrees around boot and click into LC until you hear a click.

Method Three
1. Connector Polarity
Uncrossed lines under the connector latch on the housing at both ends indicates uncrossed fiber polarity A-B/B-A.

1
2. Unlock Front Housing on One End
Push the keys on either side to unlock the housing to remove the front section of the Uniboot housing.

2

3. Remove Front Housing
Slide the front housing away from the rest of the Uniboot.

3
4. Rotate Front Housing
Flip the released section of the housing. Do not rotate or twist the fiber.

4
5. Attach Front Housing
Push the housing back over the ends and the rest of the Uniboot connector until it clicks back into place.

5
6. Connector Polarity
Finished result should now show crossed lines under the flipped connector latch and uncrossed lines on the unaltered end. This would indicate a crossed fiber polarity A-A/B-B.

Different kind of LC uniboot patch cords may have different polarity reversal design, therefore we must use different method to change the polarity. When you choose to use LC uniboot patch cords in your network, keep in mind to take the polarity reversal methods in to consideration. FS.COM LC uniboot patch cords (easily reverse the polarity with method one) terminated with premium grade zirconia ceramic ferrule connectors which help assure high transmission quality and low optical power loss and offer improved airflow and visibility of equipment within a high-density network environment.

Video Patch Panel With Patch Cable

The jacks commonly used in patch panels in the U.S. conform to Western Electric standard dimensions. The number of insertion cycles a jack can endure should be rated in the tens of thousands. The factors affecting the life and reliablility of a jack include contact wear and failure of the termination switch. Descirable features include the following:

● Contacts fully isolated from the panel.
● Sealed metal housing to keep out contaminants and provide EMI protection.
● Easy replacement from the front of the panel.
● Low VSWR (below 600 MHz)
● High signal isolation (40 dB)
● 75 Ω characteristic impedance.
● Wide designation strips, making it easier to label the field and to allow more flexibility in selecting names that will fit on the lables.

If a patch cable is inserted in the signal path of a timed video system, it will delay the signal by an amount determined by its length and physical properties. The patch thereby alters the timing of the signal path. This can be avoided by using phase-matched normal-through fiber patch panels. The design of these patch panels anticipates the delay caused by a fixed length of patch cable by including that length in the loop-through circuit.

With phase-matched panels, the normaling connection in each connector module includes a length of cable that provides a fixed delay through the panel, usually 3 ft (0.914m). If a patch cord of the same length as the internal cable is used to make connections between patch points, the delay will be the same as that of the normal-through panel. When a fiber optic patch cord is plugged in, it is substituted for the loop cable through the swiching mechanism normally used in normalled patch connectors. Thus, critical timing relationships can be maintained.

In a normal uncompensated patch panel, when a cable is used to patch between two points on the panel, the length of the patch cord is added to that of the cables connected to the patch. The additional cable length delays the signal by approximately 1.52 ns/ft (5 ns/m). To avoid the delays associated with conventional patch panels, phase-matched normal-through video patch panels should be used.

If phase-matched patch panels are used, all of the patch cord must be the same length as the delay built into the patch panel. Obviously, if all of the patch cords must be the same short length for the phase-matched panel, it would not be possible to patch between panels that are separated by a longer distance than the cord can reach. This limitation should be considered when laying out patch panels in a fiber enclosure.

Color-coded cables can be specified. When different-length patch cords are specified, different colors can be used to distinguish one length from another for better cable management.

Punch-Down Block and Patch Panel

The cable runs in a structured cabling environment terminate in a punch-down block, which is usually a 66-block or a 110-block, or BIX- or Krone-style blocks, “Cabling System Connections and Termination.” The 110-block is most commonly used for voice and data cabling termination, although you will find many installations that use a 110-block for termination voice systems and patch panel for terminating data systems. Punch-down block termination provides a cross-connect from one cable set to another, allowing for easier moves, adds, and changes (MACs) as the need arises.

What Is A Punch-Down Block?

A punch-down block is mounted to a backboard, which is usually made of plywood and secured to the wall of a TC. If you install cabling on more than the floor, each floor must have a separate punch-down block with terminations for the cable drops from the higher floors. Backbone cables should be installed with 10-foot service coils at the termination points, which are commonly located on the backboard in the closet. Figure 1 illustrates a typical TC.

Install patch cables from the punch-down block to a patch panel. The purpose of the patch panel is to connect the backbone system to networking equipment such as a hub or router. End-user equipment, which includes workstations, network printers and scanners, and other shared electronic equipment, generally connect to a hub (also called a concentrator) or router via RJ-45 cable jacks or outlets.

There are pros and cons to using cross-connect blocks. They offer higher densities and require less space than patch panels, and also are less expensive. On the other hand, they are the least friendly for making moves, adds, and changes to the configuration. Skill is involved in removing and rea-ranging cables. When using patch panels, almost anyone can rearrange the system. In both situations security, ease of attachment, expense, and physical space are all considerations.

What Is Fiber Optic Patch Panel?

Fiber optic patch panel is commonly used in fiber optic management unit. When you install and manage the fiber optic links, you may encounter hundreds or even thousands of fiber optic cables and cable connections, fiber optic management products are used to offer space and protection for the fiber cables and cable links, and they make it easier for the cable management and troubleshoot work. Our fiber optic patch panels are all sliding type, they are compatible to use with equipment and cable assembly products from other companies. Now you can see the two products from our store.
