Fiber Performance Specifications

Attenuation: reduction in optical power when passing through a fiber, usually expressed in decibels (dB). With respect to fiber, we talk about the attenuation or attenuation coefficient per unit length, in dB / km. Refer to optical loss.

Bandwidth: a range of signal frequencies or bit rate in which a component, link or fiber-optic signal operates.

Decibels (dB): a unit of measurement of the optical power that indicates the relative power. For example, 3 dB is a factor or two, 10 dB is a factor of ten. The dB in negative values ​​indicate a loss, so -10 dB implies a 10-fold reduction in power, -20 dB implies another 10 times or a total of 100 times, -30 implies another 10 or a total of 1000 and so on.

dB: optical power relative to an arbitrary zero level, used to measure loss.

dBm: optical power with 1 milliwatt reference, used to measure the absolute optical power from the transmitters or receivers. Refer to optical power.

Optical loss: the amount of optical power lost when light is transmitted through fiber, splices, couplers; It is expressed in "dB".

Optical power: measured in "dBm" or decibels with a reference power of one milliwatt. While the loss is a relative reading, the optical power is an absolute measurement, with reference standards. One measures the optical power to test the transmitters or receivers and the relative power in "dB" to test the loss.

Dispersion: pulse propagation caused by modes in multimode fiber (modal dispersion), the difference in light speed of different wavelengths (CD or chromatic dispersion in single-mode or multimode fibers) or polarization (PMD or dispersion by mode of single-mode fiber polarization).

Fiber optic cable certification

Refraction: the change of direction of the light after colliding with small particles that cause most of the loss in the optical fiber and is used to make measurements with an OTDR (optical reflectometer in the time domain).

Wavelength: Term for the color of light, usually expressed in nanometers (nm) or microns (m). Fiber is mostly used in the infrared region where light is invisible to the human eye. Most fiber specifications (attenuation, dispersion) depend on the wavelength.

How Much Does a Fiber Optic Technician Earn

Fiber optic technicians are in demand.

Patience is no longer part of the public vocabulary when it comes to the Internet. You connect something to a search engine and expect results in a few seconds. However, when Internet traffic increases, data transmission slows down and you may find yourself waiting at peak times. This is where glass fibers come into play. To take account of the increasing use of computers, smartphones, and other communication devices, companies are turning to these fibers and need technicians to install and repair cables. Technicians with industry experience can expect better profits than those who are just starting out.

Content overview
In 2011, installers and repairers of telecommunications lines averaged $ 51.330 per year, according to the Bureau of Labor Statistics. But high salaries can sometimes skew the average, and average wages are often a better indicator of a technician's income. Half of all installers and repairers earned less than $ 51,720 a year. However, these figures do not reflect experience, nor do they take into account the size of the company - factors that affect your earnings potential.
How much does a fiber optic technician make
Experience
A survey conducted by Modis, an IT recruiter, shows what you can expect from salary throughout your career. With less than three years of experience, you can earn anywhere from $ 34,600 to $ 57,700 anywhere, but the average is closer to $ 46,600 than in 2012. With two to five years in the job, salaries average around $ 55,800. After five or more years, your experience can earn an average of $ 67,300.

Job outlook
Over 2020, telecommunications technicians should see 14 percent growth in employment, reports the Bureau of Labor Statistics. This is the national average of growth for all U.S. professions. As more and more people rely on the Internet, additional fiber optic lines are required to meet increasing usage and increase the need for more technicians.

Laying fiber in asphalt - a new fiber optic construction technique

Today, the problem of congestion in cable ducts is becoming more and more urgent, which can be solved with the help of microtrench laying of fiber optic cables.
 Brief information about the asphalt plastic sewer stacker (trencher) is presented. He cuts the asphalt in the city with a cutter to a depth of 40 cm, lays plastic pipes and fills the gap with high-strength concrete. Obstacles with this method of laying can only be tram rails and hatches. The top of the gap is first temporarily closed with a special tape, then laid with asphalt. Pavement restoration - complete and hardened at the cutting site. Sewerage construction rate up to 500 m per shift.

Improving telecommunication equipment can significantly reduce the area occupied by station equipment, while repeatedly increasing capacity.

Regarding linear structures, such trends, unfortunately, are practically not observed. The development of networks of telecom operators, as well as departmental networks leads to the fact that the existing cable ducts are overloaded, and additional cabling is impossible. In addition, it should be borne in mind that fiber-optic cables must be laid in the free channels of cable ducts, into which other fiber-optic cables can subsequently be laid. In the channel of cable ducts occupied by a cable with metal conductors, joint laying of fiber-optic cables is allowed only in a protective polyethylene tube. However, often in the channels there is no place for laying cables in polyethylene pipes. In such a situation, it is necessary to carry out the reporting of cable ducts, and this is a very expensive procedure. Most often, it becomes necessary to report channels in the central regions, which are already oversaturated with underground communications (these are, as a rule, areas with high business activity).

It should be noted that the gap entails numerous inconveniences: it creates obstacles to the movement of vehicles and pedestrians, worsens the appearance of the streets. At intersections with communications of third-party organizations, it is necessary to involve representatives of these organizations. Work often has to be done on a tight schedule, including at night. For pedestrians to move through the zones of disruption, temporary crossings with fences are arranged, and lighting is provided at night. In addition, at the end of the work, re-cultivation measures are carried out, as well as restoration of the road surface (asphalting, laying of tiles, etc.). Current guidelines recommend manual digging of trenches and foundation pits in cramped urban areas. This creates additional problems. especially in winter. The city authorities are reluctant to allow digging in the central areas of the city. Thus, there is a whole range of problems that impede the development of wired networks in areas where they are most needed. The search for solutions to these problems makes us turn to the experience of foreign partners. One of the effective methods is the use of microtrench laying of fiber optic cables.

Microtrenching mechanisms
The technique of microtrench laying is based on the use of specialized mechanisms. They are a milling cutter on the tractor chassis for removing pavement and a device for removing dust, sand, gravel and other small fractions. These mechanisms can be combined into one or, conversely, divided, accordingly distributing the technological operation of preparing the trench for cable installation in two stages - opening the asphalt and cleaning the microtrench. As a cleaning device, a compressor can be used, as well as a vacuum or water pump. Accordingly, foreign particles are blown out by the air stream, sucked off or washed out by the water stream, which is supplied under pressure.

As a rule, cable laying in the ground is carried out in a trench to a depth of 1.2 m (except for rocky and other dense soils of category IV and above) in accordance with applicable standards. Such a depth is considered sufficient to reliably protect the line-cable structures operated outdoors, from unauthorized access and environmental factors. In urban conditions, cable management is being built to streamline communications, which provides additional protection for line-cable structures.
Fiber optic jobs salary
Various fiber optic cable developers offer different technology options for cable laying in a microtrench. These options have a common technological operation - deepening. The idea of ​​microtrench technology is to provide reliable cable protection with a significant reduction in earthworks. An additional protection against the most likely external mechanical and temperature effects is the roadway itself.

The book is intended for a wide range of readers: students, engineering and technical workers, scientists interested in this topic and professionally associated with the development or operation of fiber optic technology.
Types of optical fibers.
The industry produces single-mode and multimode optical fibers for various applications. To classify the manufactured types of optical fibers, international standards have been developed. The standards were developed by two organizations: the International Telecommunication Union, the Telecommunication Standardization Sector (ITU-T), mainly for fiber consumers, and the International Electrotechnical Commission (IEC), for optical fiber manufacturers.

Consider the ITU-T recommendations regarding the parameters of optical fibers.

G.650 gives general definitions of fiber types, a list of the main characteristics and parameters of single-mode fibers, as well as methods for measuring and monitoring these parameters.

G.651 applies to a multimode optical fiber with a core diameter of 50 μm and a sheath of 125 μm. The recommendation contains the main parameters of these fibers and acceptable standards.

G.652 applies to a standard single-mode fiber with unbiased dispersion (the value of zero chromatic dispersion is in the region of 1310 nm). The field of application of such fibers is fiber-optic transmission lines without spectral densification operating at a wavelength of optical radiation of 1310 nm.

G.653 applies to single-mode fiber oriented transmission systems operating at a wavelength of optical radiation of 1.55 microns. As shown above, the attenuation of optical signals in quartz optical fibers at this wavelength is minimal. The fiber according to this recommendation should have a zero dispersion in the region of 1.55 μm, which is achieved by a more complex refractive index profile in the cross-section. Such an optical fiber is called dispersion-shifted fiber. A type of G.653 fiber is used in fiber optic transmission lines without spectral multiplexing operating at a wavelength of optical radiation of 1550 nm.
