OM2 is another classification of multi-mode optical fiber designed for data communications. Here are some specifics about OM2 fiber:
- Core/Cladding Diameter: OM2 fiber typically has a core diameter of 50 micrometers (µm) and a cladding diameter of 125 µm.
- Wavelength: Like OM1, OM2 fibers are optimized for operation at 850nm and 1300nm wavelengths.
- Data Rate and Distance: At 850nm, OM2 can achieve 1 Gbps (Gigabit per second) data rates up to a distance of 550 meters and 10 Gbps data rates up to a distance of 82 meters.
- Jacket Color: The standard jacket color for OM2 fiber is usually orange, similar to OM1, but it’s essential to check the cable markings or specifications because the color can vary based on the manufacturer.
- Usage: OM2 fibers offer improved performance over OM1 due to their smaller core size, which allows for higher data rates and longer distances. However, with the development of OM3, OM4, and OM5 fibers, which offer even better performance for high-speed data transmissions, the use of OM2 in newer installations has diminished.
- Applications: OM2 is used in various premises applications and is suitable for Gigabit Ethernet and, to a limited extent, 10 Gigabit Ethernet.
When considering installations or upgrades, it’s crucial to evaluate the network’s current and future bandwidth and distance needs. In many scenarios, especially those involving data centers or larger enterprise networks, OM3, OM4, or OM5 might be more appropriate choices due to their superior performance characteristics.
