Description

Multimode fibers are identified by the OM (“optical mode”) designation as outlined in the ISO/IEC 11801 standard.

·         OM1 for fiber with 200/500 MHz*km overfilled launch (OFL) bandwidth at 850/1300nm (typically 62.5/125um fiber)

·         OM2 for fiber with 500/500 MHz*km OFL bandwidth at 850/1300nm (typically 50/125um fiber)

·         OM3 for laser-optimized 50um fiber having 2000 MHz*km effective modal bandwidth (EMB, also known as laser bandwidth) designed for 10 Gb/s transmission.

·         OM4 for laser-optimized 50um fiber having 4700 MHz*km EMB bandwidth designed for 10 Gb/s, 40 Gb/s, and 100 Gb/s transmission.

Application

OM1 and OM2 are widely employed for short-haul networks, local area networks (LANs) and private networks. OM3 is applied to a larger private networks. Different from the previous multi mode types OM4 is more advanced to be used for high-speed networks in data centers financial centers and corporate campuses.

Description

Available lengths : Multi mode – up to 8.8Km /  Single Mode – up to 50km

As well as fibers that work well across a range of wavelengths some are designed to work best at specific wavelengths. This is the G.656 which is also called Medium Dispersion Fiber (MDF). It is designed for local access and long haul fiber that performs well at 1460 nm and 1625 nm. This kind of fiber was developed to support long-haul systems that use CWDM and DWDM transmission over the specified wavelength range. And at the same time it allow the easier deployment of CWDM in metropolitan areas and increase the capacity of fiber in DWDM systems. G.657 is the latest standard for FTTH applications and along with G.652 is the most commonly used in last drop fiber networks.
