As a result of the development of data centers, cloud computing, and high-speed networks, the need for fiber interconnection between servers, switches, and storage has become more frequent. The traditional way of installing fiber cables is becoming complicated when you have to organize hundreds of connections in one rack. Lack of space, entangled patch cords, and complicated maintenance can negatively affect your network operations.
4U MPO-LC Patch Panel can connect MPO trunk connectors and LC duplex ports. This type of patch panel is going to organize your fiber connections better and allow you some extra space for expanding the network in the future. Below are seven advantages that will interest you.
4U MPO-LC Patch Panel Increases the Number of Fiber Ports
The choice of equipment for the data center is usually affected by the fiber port density. The increase in the number of network connections means that you will use an individual fiber connector for each connection and spend rack space on it.
MPO connectors can contain several fiber cores in one connector. A common 12-fiber MPO connector contains several optical connections through one interface. These connections are spread inside the patch panel through the LC duplex connectors used for connecting switches, servers, and other optical devices.
The OMC FTTH 4U 576F MPO&MTP-LC Patch Panel has 48 slots for modules. In addition, each module can contain one 12-fiber MPO connection divided into six LC duplex adapters, with a total of 576 fibers.
4U MPO-LC Patch Panel Helps to Use the Rack Space More Effectively
In addition to the switches and servers, a data center rack should contain patch panels and power supply devices. Bad cable management occupies space that should belong to the active network devices.
A 4U MPO-LC Patch Panel is designed to connect many fiber optic connections in a single device. MPO connections at the rear side of the device will be used for trunk cables, while LC connections at the front will help users gain access to particular fiber optic lines.
Such an approach simplifies rack layout planning and eliminates the need for many separate connection devices.
The ability to install the patch panel in 19-inch racks is a benefit, which can simplify its installation in many data centers. But engineers should allow enough free space for module replacement and cable handling, as well as regular inspections.
4U MPO-LC Patch Panel Helps to Manage Fiber Connections
The identification of hundreds of fiber connections without the help of special devices can be problematic. The crossing of patch cords can lead to disconnection of the wrong line during maintenance work.
The use of the MPO-LC panel will divide the system into several manageable parts. While trunk connections will be gathered in the rear part, LC interfaces will be located in the front part.
There are several ways to manage the cables better:
- Labeling ports with specific numbers.
- Using color codes to differentiate between fiber types and connections’ functions.
- Grouping connections according to racks, switches, or zones.
- Separate routing of patch cords and avoidance of their tangles.
All of these practices will facilitate the understanding of the scheme and shorten the time of searching for particular connections.
4U MPO-LC Patch Panel Accelerates the Process of Installation and Deployment
The installation of hundreds of fiber connections can be typical for large data center projects. But the completion of every termination and splicing on-site can require additional time and manpower.
Pre-terminated MPO-LC assemblies are often employed in the system. In that case, the MPO trunk is terminated in advance, whereas the module distributes the fibers in LC interfaces. Such an approach helps minimize the field termination labor required for system deployment.
Amongst the main installation benefits of using a pre-terminated MPO-LC solution, one may distinguish:
- Decreased on-site termination: Pre-terminated assemblies allow minimizing the number of individual splices.
- Simplified connection: There is a clear division of functions between MPO trunk interfaces and LC equipment interfaces.
- Rapid deployment: Individual parts may be manufactured prior to going to the installation site.
It is critical to check the MPO connector gender, fiber count, polarity, and LC interface configuration prior to connecting all components. Otherwise, there will be no ability to transmit signals through the system.
4U MPO-LC Patch Panel Facilitates Network Maintenance and Troubleshooting
After the network becomes operational, there appears to be a necessity to constantly change ports, substitute patch cords, and investigate possible signal transmission issues. Poor organization of the panel may become an obstacle.
Due to the modular structure of the 4U MPO-LC Patch Panel, connections may be subdivided into separate units. In case some module requires troubleshooting, technicians will have to examine only its connections without affecting other links.
For regular maintenance, the following measures may be taken:
- Connector inspection: Check MPO and LC end faces for dirt, oil traces, scratches, or any other contamination.
- Loss optical testing: Use an optical power meter to measure the link loss and check if it meets design requirements.
- Connection inspection: Check the seating of all adapters, patch cords, and modules.
- Port documentation: Document all changes in cables and port assignments.
Using an OTDR, it is also possible to identify the location of abnormal loss points in the fiber link. Proper documentation of the connections will greatly simplify future troubleshooting.
4U MPO-LC Patch Panel Provides Better Opportunities for Network Expansion
Requirements of the data center almost never remain stable. An increasing number of servers, new switches, and greater bandwidth requirements may cause a need for additional fiber connections.
Thanks to the modular structure, network expansion becomes easier. Depending on the capacity left, it is possible to install and/or substitute modules and connect new trunk cables without designing an entirely new cabling structure.
Besides being employed in standard fiber cabling architecture, MPO connectivity is used in 40G, 100G, and higher architectures as well. Nevertheless, the transmission rate will depend on transceivers, fiber types, connector configuration, and the design of the link as a whole.
When planning to upgrade your fiber network, take into account:
- Current port utilization and capacity left.
- Reserved ports for possible connections.
- Requirements for single-mode or multimode fiber.
- MPO core count and polarity.
- Compatibility with upgraded network equipment.
Pre-planning all these aspects will prevent additional installation work when upgrading.
4U MPO-LC Patch Panel Enhances Protection and Connection Reliability of Fiber Cables
Under some installation conditions, fiber cables can experience bending, compression, or pulling. This can lead to microbending or macrobending losses.
A patch panel is needed to provide protection to the fiber connections. Proper cable fixation prevents excessive movement of cables during maintenance.
During operation, technicians should follow the manufacturer’s minimum bending radius requirements and avoid pulling or twisting patch cords. MPO and LC connector end faces should also be cleaned with appropriate tools before connection to prevent contamination-related signal loss.
Conclusion
OMCFTTH 4U MPO-LC Patch Panel is beneficial for managing high-density fiber connections in data centers while improving rack management and installation. Selection of proper patch panel configuration depends on several factors such as fiber capacity, MPO core count, LC interface, fiber type, and polarity.
