As non-professionals, we may not be familiar with fiber optic cable, but when we need to use it, you must understand it. This article would put emphasis on introducing the following 4 Types of Outdoor Fiber Optic Cable (that from fiber-mart.com).
Aerial Bundle Cable Standards:
1. B-230 Aluminum Wire, 1350-H19 for Electrical Purposes.
2. B-231 Aluminum Conductors, Concentric-Lay-Stranded.
3. B-232 Aluminum Conductors, Concentric-Lay-Stranded, Coated Steel Reinforced (ACSR).
4. B-399 Concentric-Lay_Stranded 6201-T81 Aluminum Alloy Conductors.
5. B498 Zinc-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR).
6. Duplex Service Drop cable meets or exceeds all applicable requirements of ANSI/ICEA S-76-474
Dry water-blocking outdoor cables: Being exploited by a dry water-blocking technology, dry water-blocking outdoor cables are designed to withstand harsh outdoor conditions. This kind of fiber optic cable is suitable for use within buildings, for outdoor installations or transitional aerial and duct applications, and for entrance facilities that require riser- or plenum-rated cable. An all-dielectric construction requires no grounding or bonding, while an armored cable construction has interlocking aluminum armor that eliminates the need for innerduct or conduit. The RoHS-compliant cable is available in singlemode (meets OS1 and proposed OS2 standards) and multimode (OM1, OM2, and10-Gbits/sec laser optimized OM3) types, and in fiber counts up to 144. This kind of fiber optic patch cord is an optimal choice under harsh environment.
Plenum outdoor cables: Plenum outdoor cables are flame-retardant and suitable for aerial, duct, riser and plenum installations. No transition splice is required when entering the building from a dedicated outside plant cable. Part of the company’s LANs solutions, these cables feature 250-µm color-coded fibers for simplified identification during installation. The loose tube design provides mechanical and environment durability, and the cable’s all-dielectric construction requires no grounding or bonding. This kind of fiber optic cable is available with 12 to 60 fibers and in 62.5- and 50-µm (including laser-optimized) and singlemode fiber outdoor versions, along with a flexible, flame-retardant, UV-resistant jacket.
Outdoor cable for factory: Featuring a proprietary pressure-extruded (core-locked) tightly bound outer jacket that firmly binds all fibers together so that the cable moves as a solid, rope-like unit, these tight-buffered cables are suited for industrial applications. This kind of fiber optic patch cable is designed with flex resistance of thousands of cycles, crush resistance of 2200 N/cm, the ability to withstand 1,000 impacts, and tensile load rating exceeding a ton. They are also constructed to withstand caustic and volatile chemicals, excessive moisture and fungus, UV exposure, and operating temperatures ranging from -55℃to 124℃. They are perfect options for factory environment.
