Product description Data rate of OC3/Fast Ethernet modules is 155Mbps. Transceivers operate on 62.5/125um multi-mode fibers and 9/125um single-mode fibers on distances up to 120Km. There are also 100Base-BX single-strand versions available for distances up to 80Km. The 155Mbps Fast Ethernet SFP modules are extremely versatile, working with any active equipment that support the Fast Ethernet SFP type of interface: Ethernet switches, routers and any other networking equipment. Our SFPs have been tested and found 100% compatible with various Ethernet switches from major manufacturers like: Cisco, Nortel, TElco Systems, Extreme, ZyXEL, D-Link or Netgear.
