Description
Overview
GAOTek QSFP 40G adopts duplex LC interface and is generally used in single-mode applications. These two kinds of optical modules have four independent optical signal receiving and transmitting channels and need to use WDM technology to multiplex and demultiplex the optical signals, to realize the transmission of optical signals on long-distance single-mode optical fibers. The transmission distance of 40G BASE-LR4 optical modules can reach 6.22 mi (10 km), while the transmission distance of 40G BASE-ER4 optical modules is longer.
