INFORMATION

Description:
   The 1.25G SFP optical module is  Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). They simultaneously comply with Gigabit Ethernet as specified in IEEE Std 802.31 and 1x and 2x Fiber Channel as defined in FC-PI 13.03.
The 1000BASE-SX (short wavelength) GBIC module operates on standard multimode fiber-optic link spans of up to 1804 feet (550 m).
The 100BASE-SX SFP module is a hot-swappable device that plugs into a Gigabit Ethernet SFP port. It provides full-duplex 100-Mbps connectivity over multimode fiber (MMF) infrastructures. The 100BASE-SX SFP operates on ordinary MMF optical link spans of up to 1.2428 miles (2 km) in length.

Features:

  l       Up to 1.25Gb/s bi-directional data links
       l       Hot-pluggable SFP footprint
  
    l       850nm , Multimode Fiber
      
l       Duplex LC connector
      
l       Very low jitter
      
 l       Up to 550m on Multimode fiber
       l       Metal enclosure, for lower EMI
      
l       Single 3.3V power supply
      
l       Low power dissipation <700mW typical
