Bare Fiber Reel - Low Water Peak SM Fiber
Description:
Low water peak dispersion unshifted single mode fibre is designed specially for optical transmission systems operating over the entire wavelength window from 1260nm to 1625nm. By suppressing the water peak that occurs near 1385nm in conventional single mode fibre due to hydroxyl (OH) ions absorption, low water peak fibre is able to open E-band (1360-1460nm) for operation, and consequently provides 100nm more usable wavelengths. Low water peak fibre is comprehensively optimized for attenuation and dispersion performance accross the entire wavelength window from 1260nm up to 1625nm and upgraded for macro-bending performance in L-band (1565-1625nm). The fibre is fully satisfying the demand for transmitting multi-channel high-speed services over one single fibre.
Application:
Thanks to its broad usable optical spectrum and outstanding optical performance, low water peak fibre is the optimum choice that supports various applications such as Ethernet, Internet Protocol (IP), Asychronous Transfer Mode (ATM), Synchronous Optical Network (SONET) and Wavelength Division Multiplexing (WDM). Low water peak fibre provides more bandwidth for backbone, metropolitan area and access networks. It enables bandwidth demanding of multi-service like voice, digital and image transmission.
Low water peak fibre is applicable in all cable types including ribbon cable, loose tube stranded cable, slotted core cable, unitube cable and tight-buffer cable.
Norms:
Low water peak fibre complies with or exceeds the ITU-T Recommendation G.652.D and the IEC60793-2-50 type B1.3 Optical Fibre Specification.
Process:
MAY Telecom’s optical fibres are manufactured using the advanced Plasma Activated Chemical Vapor Deposition (PCVD) process. Because of the inherent advantages of the process, fibres show ultra accurate refractive index (RI) profile control, excellent geometrical performance, low attenuation and etc.
The optical fibre is coated with a double layer UV curable acrylate, which gives a fibre a good protection. Designed for more stringent tight-buffer cable application, the fibre also performs perfectly in loose buffer constructions and demonstrates a high resistance to micro-bending. The coating offers an excellent stable coating strip force over a wide range of environmental conditions and the coating stripping leaves no residues on the bare glass fibre. Ribon tests show excellent performance in 60°C watersoak tests, exceeding 100 days. The fibres show high and stable values for the dynamic stress corrosion susceptibility parameter, which offers a greatly improved spplicability to the fibre when used in harsh environments.
Characteristics:
- Due to the process innovation and technical breakthrough made on the basis of the conventional single mode fibre, low water peak SM fibre has the following characteristics:
- Designed for operation over the full optical spectrum from 1260-1625nm, which provides 50% more usable wavelengths and hence the transmission capacity is increased
- Outstanding optical performance supporting high-speed transmission technologies such as DWDM and CWDM
- Being compatible with existing 1310nm equipment
- Accurate geometrical parameters that insure low splicing loss and high splicing efficiency
