データ通信用光学フィルター
Extend datacenter optical transceiver bandwidth to 100G and even higher with these filters than combine low insertion loss and PDL, and high channel isolation.
These filters enable construction of high-performance, reliable, 100G CFP/CFP2/CFP4/QSFP-28 transceivers based on the four CWDM4 wavelengths, the four LAN-WDM wavelengths, or the 850 nm wavelength range.
CWDM4 and LAN-WDM Filters
Choose CWDM4 or LAN-WDM filters at low angles of incidence (AOIs) or specify WDM filters for high AOIs plus beamsplitters with low polarization splitting.
