Polyethylene(PE)

PE is used mostly for outdoor applications. PE sheath acts as a moisture barrier as well as a protection to the core. PE will not crack or become brittle at low temperatures and will retain its mechanical properties and stability at high temperatures. PE is very resistant to water, chemical and solvents and thus used as sheath for outdoor installation. PE can be UV resistant if carbon black additive is added. It will exhibit extremely good aging properties and high UV and weather resistance.

Polyvinyl Chloride()PVC

PVC is mostly used mostly for indoor applications. It is most widely used because of its good mechanical and electrical properties combined with cheap cost. The PVC material may include special carbon black additives for being UV and weather resistant

Yu

Fire retardant PVC jacketed cables will usually meet the fl ammability requirements of UL 1581(VW-1) and IEC 60332-1. With special design, the cables can meet IEC 60332-3A/C or UL 1666 (OFNR riser grade or UL 910 (OFNP plenum grade).

H

Halogen-free,Fire-retardant(LSFH)

LSZH material is used mostly for indoor applications. When exposed to fi re it will retard fi re propagation while emitting non toxic corrosive halogen gases (halogen free as per IEC 60754-1 and IEC 60754-2) and low amounts of smoke emission as per IEC 61034-2. LSZH cables can usually meet the fl ammability requirement of UL 1581(VW-1) and IEC 60332-1. With special design, the cables can meet IEC 60332-3A/C.

9.3/125um standard single mode fi ber per ITU-T G.652D (SMF)

This most employed fiber has a simple step index structure. It is optimized for operation at the 1300 nm band and can also operate in the 1550 nm, but it is not optimized for this region. The typical chromatic dispersion at 1550nm is high at 17ps/nm-km. Dispersion compensation must be employed for high-bit-rate applications. The attenuation is typically 0.2dB/km at 1550nm and the PMD is less than 0.1ps/km. This fi ber is designed for use in long distance, high bandwidth systems such as telecommunication and CATV.

9.3/125um low water peak non dispersion shifted single mode fi ber per ITU-T G.652C

The ITU-T G.652 standard SMFs are not optimized for WDM applications due to the high attenuation around the water peak region. ITU G.652.C-compliant fibers offer extremely low attenuation around the OH peaks. The G.652.C fi ber is optimized for networks where transmission occurs across a broad range of wavelengths from 1285 nm to 1625 nm. Although G.652.C-compliant fibers offer excellent capabilities for shorter, unamplified metro and access networks, they do not fully address the needs for 1550-nm transmission. The attenuation parameter for G.652 fi ber is typically 0.2 dB/km at 1550 nm, and the PMD parameter is less than 0.1 ps/ km.

Dispersion Shifted single mode fi ber per G.653 (DSF)

Conventional SMF has a zero-dispersion wavelength that falls near the 1310-nm window band. SMF shows high dispersion values over the range between 1500 nm and 1600 nm (third window band). The trend of shifting the operating transmission wavelength from 1310 nm to 1550 nm initiated the development of a fi ber type called dispersion-shifted fi ber (DSF). DSF exhibits a zero-dispersion value around the 1550-nm wavelength where the attenuation is minimum. The DSFs are optimized for operating in the region between 1500 to 1600 nm. With the introduction of WDM systems, however, channels allocated near 1550 nm in DSF are seriously affected by noise induced as a result of nonlinear effects caused by FWM. This initiated the development of NZDSF. G.653 fi ber is rarely deployed any more and has been superseded by G.655.

Non-Zero Dispersion Shifted single mode fiber per G.655 (NZDSF)

Using nonzero dispersion-shifted fiber (NZDSF) can mitigate nonlinear characteristics. NZDSF fiber overcomes these effects by moving the zero-dispersion wavelength outside the 1550-nm operating window. The practical effect of this is to have a small but fi nite amount of chromatic dispersion at 1550 nm, which minimizes nonlinear effects, such as FWM, SPM, and XPM, which are seen in the dense wavelength-division multiplexed (DWDM) systems without the need for costly dispersion compensation. There are two fi ber families called nonzero dispersion (NZD+ and NZD–), in which the zero-dispersion value falls before and after the 1550-nm wavelength, respectively. The typical chromatic dispersion for G.655 fi ber at 1550 nm is 4.5 ps/nm-km. The attenuation for G.655 fi ber is typically 0.2 dB/km at 1550 nm, and the PMD is less than 0.1 ps/ km.

Non-Zero Dispersion Shifted single mode fiber per G.656(NZDSF)

In order to overcome the defects of G652 and G655 optical fi bers, G656 fiber is developed. G656 fibers are designed for use in long haul transmission system and metro network. CWDM and DWDM can also be applied on S+C+L bands with these types fi ber. These fibers are manufactured by PCVD process. The minimum dispersion value from 1460nm to 1625nm is greater than 2ps/nm km; the maximum value is less than 14ps/nm km. The effective area at 1550nm is around 52 to 66μm. The excellent polarization mode dispersion properties help the fi ber to meet the requirement of high bit rate transmission. The PMD co effi ciency of these fi bers is less 0.05 ps/km. By use of improved PCVD process, excellent attenuation of these fibers was obtained, the water peak around 1385nm is almost removed; attenuation from 1310nm to 1650nm is less than 0.4 dB/km, attenuation at 1550nm is less than 0.22dB/km. Excellent attenuation performance will help the fi ber to utilize the bandwidth more effectively.
