The Extreme-compatible SFP transceiver provides up to 20km of 1000Base-BX throughput over single-mode fiber (SMF) using 1550nm-TX/1310nm-RX wavelengths via LC simplex connectors. This bi-directional unit must be used with another transceiver or network equipment of complementary wavelengths. It provides 1000BASE Ethernet connectivity options for Fast Ethernet, Telecom and Data Centers.
Note: Transceiver of yellow or purple pull-tab is shipped randomly due to different batches. And the quality is the same.
