G.651-Multi-mode Optical Fiber
Standard 50/125 μm fiber
This specification covers the design requirements and performance standards for the optical fiber described
below. This fiber is used in the optical cables. The features described in this document are intended to provide information on the performance of the optical fiber and aid in handling and use. Refer to the appropriate cable specification for details regarding the finished cable’s performance.
1.1 Fiber Description
The Standard Multimode (MM) optical fiber used is a graded index fiber with glass core, glass cladding and dual acrylate protective coatings. This Type Ia TIA specified fiber is optimized for operation at both 850 and 1300 nm transmission windows. It is fully compatible with commercially available splicing and connector products and can be spliced to other commercially available 50 μm MM fibers. The 50 μm MM fiber is ideal for data and local area networks.
4SProducts ensures a continuing level of quality in our optical fiber products through multiple programs including ISO 9000. Quality product is guaranteed and is evident in the optical fiber cable products supplied by 4SProducts.
4SProducts ensures product reliability through rigorous qualification testing of each product family to meet or exceed industry standards. Both initial and periodic qualification testing are performed to assure the fiber’s performance and durability in the field environment.
2. Fiber Design
Only the highest quality Multi-Mode fibers in our cables 50 μm Multimode (MM) optical fiber manufactured by the Modified Chemical Vapor Deposition (MCVD). This highquality glass has excellent geometry, high strength characteristics, high bandwidth, and low attenuation. The MM fiber is fully compatible with other commercially available MM fibers and is optimized for transmission at 850 and 1300 nm wavelengths.
The 50 μm MM fiber is a graded index design. Its optical properties are achieved through a Germanium
doped silica based core with a pure silica cladding. A dual acrylate protective coating is applied over the glass cladding to provide the necessary bending and tensile strength required for handling in the field and to ensure maximum fiber lifetime through increased reliability.
3. Testing & Inspection
The optical properties of all fibers are measured prior to cable manufacturing with bi-directional
OTDR and remain traceable through-out the manufacturing process and the lifetime of the cable. After cabling, 100% of all fibers in each length of cable are measured at all operating wavelengths. The attenuation for each fiber is recorded.
