Multimode Fiber Optic Cable
Multimode Fiber optic Cables
The equipment used for communications over multi-mode optical fiber is much less expensive than that for single-mode optical fiber.[1] Typical transmission speed/distance limits are 100 Mbit/s for distances up to 2 km (100BASE-FX), 1 Gbit/s to 220–550 m (1000BASE-SX), and 10 Gbit/s to 300 m (10GBASE-SR).
Because of its high capacity and reliability, multi-mode optical fiber generally is used for backbone applications in buildings. An increasing number of users are taking the benefits of fiber closer to the user by running fiber to the desktop or to the zone. Standards-compliant architectures such as Centralized Cabling and fiber to the telecom enclosure offer users the ability to leverage the distance capabilities of fiber by centralizing electronics in telecommunications rooms, rather than having active electronics on each floor.
Multi-mode fibers are described by their core and cladding diameters. Thus, 62.5/125 multi-mode fiber has a core size of 62.5 micrometres and a cladding diameter of 125 µm. In addition, multi-mode fibers are described using a system of classification determined by the ISO 11801 standard - OM1, OM2, and OM3 — which is based on the modal bandwidth of the multi-mode fiber. OM4 (defined in TIA-492-AAAD) was finalized in August 2009, and was published by the end of 2009 by the TIA OM4 cable will support 125m links at 40 and 100 Gbit/s.
