Reliable and durable — What more can we say, fiber optic cables provide a reliable solution for your data transmission. The core of the fiber optic cable is made of glass, which is an insulator, so no electric current can flow through. We can easily install fiber optic cables next to industrial equipment easily and you have nothing to worry about. Fiber optic cables are also less susceptible to temperature fluctuations than copper and can be submerged in water.
Design — As opposed to copper, fiber optic cables are lightweight. With copper cables, if you want higher bandwidth than you have to use a higher grade of cable, which is typically larger and more bulky and heavy and take up more space in cable trays.
On the other hand, with fiber optic cables, the weight and diameter is far less. The petite size of the fiber optic cables makes it easier to handle, and it takes up much less space in cabling ducts, while fiber optic cables are easier to test than copper cable. Cost — One question we are asked is if fiber optic cabling is expensive? With the decrease in fiber cable, components, and hardware, the cost too has steadily decreased and is very affordable.
However, fiber optic cabling is more expensive than copper cables in the short run, but is definitely more expensive in the long run. Fiber optic cables cost less to maintain, has less downtime, requires less networking hardware and can be easily replaced. So if you are thinking about the best cabling option for your office or home-office, then talk to our experts about the best type of cable to use so that its long lasting, provides a superior performance and is cost effective.
You will still have willing buyers for its capacity because it remains relevant. And, given that broadband is an essential service that people will need their entire life, you will have a dedicated funding source. Even if it takes you 30 years to recover your costs, that still makes financial sense because fiber is expected to be useful for decades past those 30 years. An analysis by the consulting firm Conexon , which specializes in rural fiber by rural cooperatives, has found that while states across the country that received tens of millions of dollars from the federal government for broadband, almost all lack dense fiber networks—with the exception of a state like North Dakota.
Blue areas represent high-speed. How did that happen? How did nearly identical amounts of public investments in broadband yield such massive discrepancies? It boils down to the decisions the local governments and small private ISPs in North Dakota made with that government money.
Frontier ignored profitably opportunities to deploy fiber for so long that it is now undergoing bankruptcy due to its neglect. Meanwhile, in North Dakota, the local government and small private ISPs made the decision to invest those federal government dollars, and their own local investments to match, into building out fiber networks. Now those networks are being paid off in the long run. And the local, state, and federal governments no longer need to come back and spend money to replace anything there.
Those fiber networks will be able to offer symmetrical 10 gigabit services, gigabit services, and terabit services well into the 21st century. And they will able to do so without government subsidies, but rather financed by typical monthly payments from users. In essence, every dollar the government has spent to assist ISPs to slightly increase their speeds has been a waste, given that those slow speeds are no longer relevant or useful to consumers—or are rapidly approaching the cliff.
Those networks have hit their limits and only a replacement to fiber can yield further advancements. If policy required states to spend the billions the government provided on a transition to fiber 10 years ago, we would look more like South Korea today as opposed to being behind close to a dozen EU nations, the advanced Asia markets, and China.
We have updated this post to clarify the changes made to the program in August It goes by many names, but no matter how you cut it, the new San Francisco—Public investments in open access fiber networks, instead of more subsidies for broadband carriers, will bring high-speed internet on a more cost-efficient basis to millions of Americans and create an infrastructure that can handle internet growth for decades, according to a new report.
The newly minted law frees Oakland renters With great influence comes great responsibility. Many of these revelations are things we've long suspected but now have proof of: Facebook focuses on growth—of users and time spent on its platforms—to the exclusion of everything else. You might take this approach if you are having electromagnetic interference problems, such as on a factory floor, and the cost would be justifiable.
But proper design can make fiber comparable or even less expensive than copper. Your telephone and community antenna television CATV systems use fiber because it is less expensive. The designers of those networks learned early on that fiber offers new ways of designing networks. It's higher speeds and longer distance capabilities allowed new network architectures and protocols that made copper look expensive - very expensive. With today's networks, a telephone conversation costs about 1 percent as much on fiber as it does on copper.
Fiber is even beginning to look cost effective for direct connections to the home if high-speed Internet connections are desired. In premises networks, most comparisons of fiber and copper ignore the technological differences between fiber and copper wiring. So lets consider the two more correctly and see what the cost issues are.
Fiber's immunity to electromagnetic interference EMI saves you the cost of putting fiber optic cable in conduit in order to get past sources of EMI, which saves money right there. But the biggest advantage of fiber optics is its distance capability. Cat 5 or enhanced Cat 5 or Cat 6 has a meter distance limitation, which equals feet. That includes the length of the cable running up and down walls to avoid HVAC systems, fluorescent lights, electrical cables, etc.
Within an office building, this distance limitation requires a telecommunications closet close to the desktop to site electronics that connect all the desktops, multiplex the data onto a backbone which is almost always fiber optics , and connect with the LAN servers or outside connections.
This layout requires considerable electronics in each telecommunications closet. See Figure 1. These electronics require space to situate them, racks to hold them, power to power them, and often heating and air conditioning to provide a suitable environment.
Power quality is a major concern for computer networks. Everyone has a surge suppressor on their computers and many of us also have an uninterruptable power supply UPS. The electronics in the telecommunications closet have equal needs.
Power must be conditioned and sufficient UPS capability is necessary for an orderly shutdown of the system in the event of a power failure. Grounding is yet another concern. Noisy grounds and ground loops can cause errors in digital systems that slow down the network, so a dedicated data ground is required for each telecommunications closet.
Each closet then connects to a computer room via backbone cabling. Most of the large premises networks already have fiber backbones, usually due to the length limitations on Cat 5, but grounding and electromagnetic interference EMI concerns are also a problem.
The computer room has hubs and switches that connect all the hubs in the telecommunications closets to the servers. The same network looks a lot different on a centralized fiber optic cable system Figure 2 , since you no longer need local electronics in the telecommunications closet.
Fiber optic cables can allow most network connections to be 2 km feet long. Only gigabit Ethernet is limited to shorter lengths, to meters 1, to 1, feet , because all fiber does not have infinite bandwidth. The desktop is now connected on a small duplex fiber cable to a backbone cable - there are no local electronics.
The connecting box is so small it can be mounted on a wall or above a ceiling. The backbone cable can contain up to fibers, yet is still smaller than a bundle of a half-dozen Cat 5 cables.
You need no local electronics in a telecommunications closet. All electronics are now moved to the central computer facility, where they are easier to site and manage when problems arise. You already have conditioned power, an uninterruptible power supply UPS , and data grounds in the computer room, so handling the electronics is simple.
