The conversion to an optics-based access system is expected to progress rapidly as the demand for high-speed, broadband access increases with the rapid expansion of the Internet. While access equipment used in conventional SDH/SONET and Ethernet systems employ two optical fibers, there is an increasing number of systems that transmit and receive signals over a single optical fiber with the view to raising the usage efficiency of optical fiber, decreasing the number of optical fibers to be accommodated by a communications office, and eliminating the complexity of identifying and connecting two optical fibers.

Two product forms: MSA-compliant SFP and Compact SFP.
An extensive set of data rates, transmission distances, and optical-connector shape, monitoring characteristics are ready.
And furthermore the highly integrated CSFP(Compact Small-Factor Pluggable transceiver) will enable network system vendors to increase port density and data throughput, while reducing network equipment cost.
