OFNP vs. OFNR

Fiber optic cables are a vital component of modern communication networks. They are used to transmit data over long distances with minimal signal loss and interference. Two common types of fiber optic cables are OFNP (plenum) and OFNR (riser). Understanding the differences between these two types of fiber optic cables is crucial in making the right choice for your communication network.

OFNP (Optical Fiber Non-conductive Plenum) cables are used in air-handling spaces and plenum areas in buildings. Plenum areas are those spaces that allow air circulation for heating, ventilation, and air conditioning (HVAC) systems. OFNP cables are made of fire-resistant materials and are required to meet strict fire safety codes. They emit low levels of smoke and toxic fumes, making them suitable for use in areas where smoke and toxic fumes could be dangerous in the event of a fire.

OFNR (Optical Fiber Non-conductive Riser) cables, on the other hand, are used in vertical risers or pathways in buildings. They do not emit low levels of smoke and toxic fumes and are not required to meet the strict fire safety codes of OFNP cables. OFNR cables are less expensive than OFNP cables and are typically used in non-critical areas where fire safety is not a major concern.

When it comes to transmission performance, they are identical. They both offer high bandwidth and low signal loss, making them ideal for transmitting large amounts of data over long distances. However, OFNP cables are typically more expensive than OFNR due to the compounds used in the manufacturing process for the outer jacket. 

In conclusion, the choice between OFNP and OFNR fiber optic cables depends on the specific requirements of your communication network. OFNP cables are ideal for use in air handling spaces and plenum areas where fire safety is a concern, while OFNR cables are suitable for use in non-critical areas where fire safety is not a major concern. OFNP cables can always be used in place of OFNR, but not vice versa. 

Different types of optical fiber cables exist for various fire ratings, which can make choosing the appropriate one a challenging task. To aid those who are planning or installing a fiber network, UL 1651 is a critical guideline for ensuring the correct selection of fiber. The National Electric Code (NEC) Article 770.19 outlines these guidelines, but some commonly used measures include:

  • OFNP, OFCP, OFNR, OFCR,OFNG, OFCG, OFN, OFC for small, in-building deployments using a riser
  • OFNP, OFCP for existing fabricated ducts within a building
  • OFNP, OFCP for plenum spaces used for environmental air in public buildings
  • OFNP, OFCP, OFNR, OFCR,OFNG, OFCG, OFN, OFC for fireproof shafts using a riser in any building type
  • OFNP, OFCP, OFNR, OFCR,OFNG, OFCG, OFN, OFC when using a metal raceway for in-building deployments covering multiple floors and rooms/apartments
  • OFNP, OFCP, OFNR, OFCR for vertical runs between floors within a riser
  • OFNP, OFCP, OFNR, OFCR for riser cable routing assemblies inside a building
  • OFNP, OFCP, OFNR, OFCR,OFNG, OFCG, OFN, OFC for in-building deployments with routing on only one floor.

OFNR vs. OFNP

Cable jackets are comprised of different materials based on different applications. Plastics used in the structure of plenum cable in the United States are regulated under the National Fire Protection Association standard NFPA 90A: Standard for the Installation of Air Conditioning and Ventilating Systems. All materials planned for use on wire and cables to be placed in plenum spaces are intended to meet rigorous fire safety test standards by NFPA 262 and outlined in NFPA 90A.

OFNR (Optical Fiber Non-conductive Riser)

Used in riser applications or spaces inside a building in pathways that pass between floors, such as a vertical zone or space. They are engineered to prevent a fire from spreading from floor to floor within buildings. OFNR cable is resistant to oxidation and degradation. It gives off heavy black smoke, hydrochloric acid, and other toxic gases when it burns. It is fine to use as a patch cord or for single in-wall runs. If you want to use it in a building, the building must feature a contained ventilation system and have good fire exits.

OFNP (Optical Fiber Non-conductive Plenum)

Used in plenum applications or inside buildings in plenum areas, the areas between a ceiling and the floor above it, where space is reserved for the circulation of air. They have the highest rated fire retardant which emits little smoke during combustion. The non-conductive element within OFNP means they contain no electrically conductive components. OFNP cable has fire resistance and gives low smoke when it burns. It can be used as a substitute for PVC (OFNR) cable since its fire resistance is the highest. It’s designed for the movement of environmental air and is commonly used for vertical runs between floors.

DMSI utilizes UL-listed cables in all our products. UL-listed cables are fully traceable and guarantee high quality and safe product. To combat counterfeit offshore cables, we recommend asking your suppliers for a certificate of compliance, or proof of where your product is coming from.

Why 5G Wireless Need Lots of Fiber?

To be fully functional, 5G will depend on fiber.

The most recent development in wireless network infrastructure is a fifth generation, AKA, 5G. This will cover up to 100 times more connected devices, including both mobile and fixed network infrastructure.

Superficially, people would think that 5G technology will eliminate the need for fiber cables. Quite the reverse, the future 5G’s success significantly depends on fiber.

Fiber is Substantial to Increase the Speed

5G promised to increase to speed up to 10 Gbps, which is ten to a hundred times higher than 4G. Among all mediums, fiber is the best future-proof choice that is capable of transporting data at a long distance and high bandwidth.

Better Performance Requires Fiber

The goal of the 5G network to accomplish diversity, availability, and coverage can be achieved by wider deployment of smaller cell sites/distributed antenna systems (DAS) interconnected by fiber instead of a few larger ones in favor of utilizing the capabilities in an area. To meet this goal, there will need to be more fiber used worldwide because copper or air options will not be able to sustain this.

Affordability

Fiber is the best all around option because of its cost-effectiveness and durability.

Fiber is Here to Stay

5G wireless and fiber will go hand in hand. Its placement will significantly depend on the availability of fiber infrastructure. In the future generation of wireless network, fiber will be valuable with an improvement of capacity and lower latency.

Why You Need Low-Loss Fiber Connectivity

In any data center, the key for each manager is to maintain efficiency and set your network up for optimal connectivity. However, things do not always go to plan every single day, and you have to factor that into your business. There are plenty of factors that contribute to link loss, such as the length and type of cable, or the number of connectors. Low-loss MPO or MTP connectors will give you greater adaptability and flexibility. The biggest thing to remember with any type of fiber optics product is that your daily tasks will be made simple. Processes that used to take up time will now be done in a much more efficient manner. With low-loss connectivity, your functionality will increase, such as expanding the distance of your network due to the number of connections possible.


With low-loss connectivity, your functionality will increase, such as expanding the distance of your network due to the number of connections possible.

How Will It Help?

As with anything in this sector, or any sector really, the key is to minimize risk. By using low-loss fiber connectivity, you’re effectively shrinking the risk that would’ve been there. In today’s data centers, optical insertion budgets are shrinking. It’s also important to recognize that much of the architecture for layouts has become flattened. Considering LANs now have higher port densities, flatter networks have become more prevalent. So, this isn’t necessarily something you have to do, but it would bring you incredible value.

What Are The Benefits?

The benefit of having low-loss fiber connectivity is that it gives you a greater amount of connection points. Specifically, more connection points in 10, 40, and 100 gigabit Ethernet channels. Another main benefit of using this type of technology is how much easier it makes for simple processes. With the low loss, fiber makes it much easier (and faster) to change your server connections between ports.

The Potential Damage That Can Harm Your Cables


Fiber Optics will be at the forefront of communication for years to come, but like all things, there are ways in which they can be harmed.

Whether it’s a family home or a business, many people are making the switch to fiber optic cables due to the increased efficiency that they bring. Not only are they more effective than copper wires, but they’re lighter and faster as well. Fiber Optics will be at the forefront of communication for years to come, but like all things, there are ways in which they can be harmed.

Recklessness

With a product like this, a primary concern is with those that try to steal. Thievery is always a problem, and with fiber optic cables, it happens more than you’d think. Many times, robbers will see fiber optics and mistake them for a form of metal, which translates to money in their minds. Therefore, they will attempt to steal in hopes of reselling the cables. Fiber optics don’t contain metal, but people will still try to displace them.

Weather

The beauty of fiber optic cables is that they are designed to outlast any type of normal weather precipitation. However, in the event of a large-scale scenario (such as an earthquake), the cables will suffer from damage. Now, natural disasters are rare occasions, but even in normal conditions, it’s still important to get your cables regularly checked to maintain peak efficiency.

Harm From Animals

When fiber optic cables are installed, they are typically placed underground or through the interior of a building. Naturally, there are a variety of animals that can come into contact with the cables. Whether it’s rodents throughout the house or animals venturing in from outside areas, there’s a small chance they could end up disturbing your setup. If this happens, make sure to have your cables examined. This is also why it’s smart to schedule regular checkups for efficiency, in case something like that does happen.

Fiber Optics Are Being Used in the Art of Avionics

While fiber optics used within the networking industry are changing the way we see the internet, the same kind of cabling can be used for other advantages.

Fiber optics are a growing aspect of our technology in almost every field of work. For many, this is an exciting process. We’ve already discussed how fiber optics are being used to detect blood clots, which can save lives; medical professionals have rejoiced over this new technology, which has allowed them to work more effectively. And, while fiber optics used within the networking industry are changing the way we see the internet, the same kind of cabling can be used for other advantages. In this week’s blog, we’re going to explore how fiber optics are being used for avionic technology.

Unmanned Aircraft

When it comes to building these devices, the fiber optics industry has taken over. The cables make it easier than ever to communicate data and video. Using fiber optics, or fly-by-light technology, unmanned aircraft become lighter. They also cost much less. This technology has already been implemented in larger, manned aircraft; but, condensing the cable system within smaller devices will soon be a common practice. Another fantastic benefit of using fiber optics is that it cannot be affected by interference or electromagnetic fields. The signal will never fade, allowing the drones to be used to their full potential.

Commercial Flights

Even in commercial avionics, fiber optics have played a huge role. They’re being used for in-flight entertainment, allowing for faster streaming and better connection. This technology is much less expensive. Likewise, fiber optics can even be used for safety equipment. For example, it can be used for the technology that lowers emergency oxygen masks in the case of an emergency. This ensures a lower rate of malfunction, and a faster response time if disaster strikes.

Benefits

Even years ago, in 2009, the market for fiber optics in the avionics industry was estimated to be $309 million. It has grown exponentially since then, in both military and commercial flying technology. Fiber optic cables weigh less, cost less, are faster, and more efficient than their copper cable counterparts. It’s no wonder that such brilliant technology is being used for an incredibly important area such as avionics.
