Gibson Technical Services was originally founded in 1990. The goal was then to provide design and consulting services and assistance for cable system operators and equipment manufacturers. Twenty years later, GTS still works hard to provide its valued clientele the best services possible, with a scope of expertise ranging from Fiber Optic Services to towers and civil construction, without forgetting an ensemble of professional data services; Voice-over IP, network consulting, digital video surveillance, network security, structured cabling and network analysing.

The Fiber Optic Services offered by GTS allows clients to be assisted at all moments through the process and get the support they need before, during and after the installation of the entire network and system. Gibson Technical Services offers cable route planning, optical fiber splice planning, optical coupler planning, fiber network audits, optical fiber fusion splicing, OTDR testing, optical loss measurements and fiber management system installation as part of their comprehensive range of fiber optic-related services. Clients are guided through the process and offered all the support and assistance necessary to the success of the operations.

Since Gibson Technical Services’ reputation was built and still stands on the quality of the services as well as the satisfaction of its numerous clients, it goes without a saying that the team behind GTS is highly skilled and trained and provides clients with an unprecedented expertise and competence. To offer the best Fiber Optic Services, GTS is proud to work with Mike McCraken, Chief Technology Officer. McCraken has a tremendous amount of experience related to network planning and fiber optic systems and brings more than 23 years of knowledge to Gibson Technical Services. McCraken is joined by two other notable officers, Jon Martin and Robert Moore [Chief Operating Officer and Chief Financial Officer].

For all Fiber Optic needs and wants, Gibson Technical Services is the name to remember. With their experience and devotion to their clients, GTS surely has made a reputation of its own as being a reliable and understanding company who works for the benefit of the clients first and foremost. GTS services many areas, with current operations in Georgia, Alabama, Mississippi, Louisiana, Florida, Ohio, Pennsylvania, Maryland, Nevada, North Carolina and Puerto Rico, amongst other locations..

2 optical isolator principle
Optical isolator using magnetic optical crystal Faraday effect ( also known as the Faraday effect ). In 1845, Faraday first observed with optical material under the action of magnetic field to make the material in the direction of polarization rotation, therefore often called the Faraday effect. In Faraday effect, the rotation of the polarization direction direction and magnetic field, and the orientation of the light transmitting is independent of the forward and reverse, and we usually in the index of refraction, reflection phenomena seen in the reversibility of optical path difference. Along the magnetic field direction of transmission line polarized, the polarization direction rotating angle ??and magnetic field strength of B and L is proportional to the product of the length of the material, the proportion coefficient is what we often say that the Wilde constant. Optical isolator based on polarization characteristics can be divided into polarization-independent and polarization dependent type. These two kinds of isolators are used with the Faraday effect in magneto-optic crystal, Faraday magnetic medium in 1~2?? m wavelength range usually adopts the optical loss low yttrium iron garnet ( YIG ) single crystals. Model of input and output of the fiber optical isolator has fairly good performance, the minimum insertion loss of approximately 0.5 dB, the isolation of up to 35??? 60 dB, a maximum of 70 dB. The optical isolator using most still is polarization independent type, its principle is shown in Figure 1, using the forward and reverse transmission optical path is inconsistent, it is this time signal transmission is not reversible, thereby forming isolation. The typical structure of only four major components: the magnetic ring, a Faraday rotator, two pieces of LiNbO3 wedge angle piece, with a pair of fiber collimator, can be made into an in-line optical isolators.
Positive transmission: the parallel light beam from the collimator, into the first wedge angle piece P1, beam is divided into o light and e light, the polarization direction perpendicular to the propagation direction, forming an included angle. When they pass through 45o Faraday rotator, emitted by the o light and e light polarizing surfaces of respective to the same direction of rotation 45o, because the second wedge-shaped plate P2 crystal axis relative to the first wedge angle piece is just in a 45o angle, so o light and e light is refracted into a small space, synthesis. Parallel light, and then by another collimator is coupled to the optical fiber core. In this case, the input optical power only a very small fraction of outage, this loss is called isolator insertion loss..
