Single-modeStandardBrb Cable utilizes Corning®SMF-28e+®TM fiber as its standard sing-mode offering. This is a full-spectrum fiber that is full backward-compatible with legacy single mode fiber. It enables increased optical lunch power of legacy single mode fiber, improved macro band specification from 0.05 dB to 0.03 dB, and tighter zero dispersion wavelength (?o) tolerance from a range of ±10 nm to ± 7 nm. This fiber Supports all broadband application and complies with the most stringent industry standards, such as:
" ITU-T G.652(Table A,B,C and D)" IEC 60793-2-50 Type B 1.3" ISO 11801 052" TIA/EIA 492-CAAB" Telecordia GR-20-CORE
An optical fiber cable is a type of cable that has a number of optical fibers bundled together, which are normally covered in their individual protective plastic covers.
BRB Cable, Corning®Optical Fiber. Name that are synonymous with cable and fiber combine to create the ultimate in fiber optics.

The fiber of single-mode are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water resistant filling compound. A steel wire sheathed with polyethylene locates in the center of a core as a metallic strength member. The tubes are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protect it from water ingress. Then the cable core is covered with a PE sheath.

The fibers of single-mode are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water resistant filling compound. A place of fiber reinforced plastic locates in the center of a core as a non metallic strength member. The tubes are stranded around the strength member into a compact and circular cable core. An Aluminium Polyethylene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protect it from water ingress. The cable is completed with a polyethylene (PE) sheath.

The fibers of single-mode are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water resistant filling compound. A place of fiber reinforced plastic locates in the center of a core as a non metallic strength member. The tubes are stranded around the strength member into a compact and circular cable core. An Aluminum Polyethy_lene Laminate (APL) is applied around the cable core, which is filled with the filling compound to protect it from water ingress. Then the cable core is covered with a thin PE inner sheath. After the PSP is longitudinally applied over the inner sheath. The cable is completed with a polyethylene (PE) sheath.
The fiber of single-mode are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water resistant filling compound. A layer of aramid yam is around the cable core as additional strength member. Then, the cable is completed with a black or colore.

Zero-Dispersion Wavelength:In a single-mode optical fiber, the wavelength at which material dispersion and waveguide dispersion cancel one another. The wavelength of maximum and Width in the fiber. Also called zero- dispersion point.
Zero-dispersion Slope:In single-mode fiber, the rate of change of dispersion with respect to wavelength, at the fiber's zero dispersion wavelengths.
Mode Field:The single-mode field distribution giving rise to a spatial intensity distribution in the fiber.
Numerical Aperture:The numerical aperture (NA) is the sine of the vertex half-angle of the largest cone of rays that can enter or leave the core of an optical fiber, multiplied by the refractive index of the medium in which the vertex of the core is located.
Zero Water Peak (ZWP):The reduction of water absorption characteristics on conventional single-mode fibers, which minimized signal loss to make more wavelengths available for high quality transmission. These fibers allow 50% more channels by opening up the wavelength range around 1400 nm.
Refractive Index:Ratio of the wavelength or phase velocity of an electromagnetic wave (light) in a vacuum to that in a medium.
Refractive Index profiles:The distribution of the refractive index along a diameter of an optical fiber.
Bandwidth (BW)The range of frequencies within which a fiber optic waveguide or terminal device can transmit data or information.
