   This Small Form-factor Pluggable (SFP) fiber module supports Gigabit Ethernet transmission over multimode fiber cable with a 220m Span on 62.5µm Fiber and a 550m Span on 50µm Fiber. It adheres to the IEEE 802.3z standards for Gigabit Ethernet fiber connectivity, and is a cost-effective method of providing changeable Gigabit Ethernet fiber optic interfaces to switches and media converters equipped with a standard SFP slot.

Key Features:

  • Compliant with SFP MultiSource Agreement
  • Compliant with IEEE802.3Z
  • SCA-2 Host connector
  • Duplex LC connector
  • 3.3V power supply
  • Five-year warranty
  • Standard Temperature Range (0° C to 70° C)

 ** Maximum distances attainable on multimode Gigabit Ethernet fiber circuits are primarily dependent upon multimode distortion, also known as modal dispersion. Larger aperture fiber optic cable allows more modes to be generated at the launch point; these modes cause the pulse width to spread across a Gigabit Ethernet bit time interval to a point where accurate determination of data (i.e., ones and zeroes) is not possible. These are physical properties that are not specific to this product. These properties also apply to competing products operating in the same frequency spectrum over multimode fiber cable having the same modal bandwidth.
