Extralink WDM Bi-Directional SFP Optical Transceiver Module

Extralink SFP 1.25G | SFP WDM Module | 1,25Gbps, 1310/1550nm, single mode, 20km, Fits any Intellinet Gigabit Ethernet switch with SFP module slots, or any MSA or Cisco compliant SFP port. Must be used with Gigabit Fiber WDM Bi-Directional SFP Optical Transceiver Module, Intellinet model 507509 or Cisco model GLC-BX-U. WDM (bi-directional wavelength division multiplexing) Technology Advantage - The Intellinet Network Solutions Gigabit Fiber WDM Bi-Directional SFP Optical Transceiver Module utilizes a single strand of fiber to transmit network traffic on separate receive and transmit wavelengths (1310/1550 nm). This innovative technology allows you to effectively use the two strands for two independent connections or to double the capacity without laying a second fiber cable.
