FAQ:
What is fiber Optics:
An optical fiber (or fibre) is a glass or plastic fiber designed to guide light along its length. Fiber optics is the overlap of applied science and engineering concerned with such optical fibers. Optical fibers are widely used in fiber-optic communication, which permits transmission over longer distances and at higher data rates than other forms of wired and wireless communications.
               

What's a fusion splicer ?
A Fusion Splicer is specialized instrument used to join Optical fibers  to each other. The generally accepted splicing method is arc fusion splicing, which melts the fiber ends together with an electric arc.

How is Fusion splicing done?
Fusion splicing is done with a specialized instrument that typically operates as follows: The two cable ends are fastened inside a splice enclosure that will protect the splices, and the fiber ends are stripped of their protective polymer coating (as well as the more sturdy outer jacket, if present). The ends are cleaved (cut) with a precision cleaver to make them perpendicular, and are placed into special holders in the splicer. The splice is usually inspected via a magnified viewing screen to check the cleaves before and after the splice. The splicer uses small motors to align the end faces together, and emits a small spark between electrodes at the gap to burn off dust and moisture. Then the splicer generates a larger spark that raises the temperature above the melting point of the glass, fusing the ends together permanently. The location and energy of the spark is carefully controlled so that the molten core and cladding don't mix, and this minimizes optical loss. A splice loss estimate is measured by the splicer, by directing light through the cladding on one side and measuring the light leaking from the cladding on the other side.
                        

Brands of fusion splicers we supply ?
At Sunrise we supply several brands and models of Fusion Splicers, which include  leading brands and manufacturers like Furukawa (Fitel S177A , Fitel S176 , Fitel S122m12, ect) , Sumitomo ( Type 65,Type 66, Type 37se, ect),  Fujikura (FSM 50S , FSM 40S , FSM 50R , FSM 45 PM , ect) , as well as some other OEM
(Original Equipment manufacturer) types which are very similar to the in specs and performance to the leading brands. Link to our Fusion Splicer page.
 

What's OTDR ?
In telecommunication, an optical time domain reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber.

How is OTDR Testing done ?
An OTDR injects a series of optical pulses into the fiber under test. It also extracts, from the same end of the fiber, light that is scattered back and reflected back from points in the fiber where the index of refraction changes. (This is equivalent to the way that an electronic TDR measures reflections caused by changes in the impedance of the cable under test.) The intensity of the return pulses is measured and integrated as a function of time, and is plotted as a function of fiber length.

Usages of OTDR
An OTDR may be used for estimating the fiber's length and overall attenuation, including splice and mated-connector losses. It may also be used to locate faults, such as breaks.

Brands of OTDR's we supply ?
We supply a wide range of OTDR testers . Link to our OTDR Testers  page

What's CMTS?
A cable modem termination system or CMTS is equipment typically found in a cable company's headend, or at cable company hub site and is used to provide high speed data services, such as cable internet or Voice over IP, to cable subscribers.

How Does it Work?
In order to provide these high speed data services, a cable company will connect its headend to the Internet via very high capacity data links to a network service provider. On the subscriber side of the headend, the CMTS enables the communication with subscribers' cable modems. One way to think of a CMTS is to imagine a router with Ethernet interfaces (connections) on one side and coax RF interfaces on the other side. The RF/coax interfaces carry RF signals to and from the subscriber's cable modem.

Brands of CMTS we supply ?
We only supply one type of CMTS (OEM) , which can provide supply CATV users high-speed internet access, Video-On-Demand,SOHO, long-distance education,   IP phone, etc at a very low cost. Link to our CMTS page.
