QSFP/QSFP+ Passive Electrical Loopback FTCQ-XLB is used for testing QSFP/QSFP+ transceiver ports in board level test. The electrical loopback provides a cost effective low loss method for QSFP/QSFP+ port testing. The FTCQ-XLB is packaged in a standard MSA housing compatible with all QSFP/QSFP+ ports.

基于IEEE-100GBASE-LR4規(guī)范，此產(chǎn)品典型功耗只有3.5W，比當(dāng)前業(yè)界最好的100G CFP4模塊功耗低40%。它采用最先進(jìn)的100G傳輸技術(shù)為數(shù)據(jù)中心提供機(jī)架交換機(jī)和核心網(wǎng)之間的連接，比40G QSFP方案提高了150%的面板帶寬密度。相比于當(dāng)前只支持12個模塊/單板的100G CFP2，QSFP28可以支持多達(dá)48個模塊/單板。100G LR4 QSFP28為目前超大型數(shù)據(jù)中心不斷增加傳輸距離的需求提供了理想解決方案，并將引領(lǐng)單模光纖在數(shù)據(jù)中心的使用。

F-tone 40GBASE-LR4 QSFP Module supports link lengths of up to 10km over a standard pair of G.652 single-mode fiber with duplex LC connectors. The 40Gbps QSFP+ transceiver is well suited for Infiniband and 40GBASE-LR4 applications. It combines the higher density attractions of parallel modules with some of the key advantages normally associated with SFP+ based modules.
