Transceivers (40G QSFP & CFP)
The QFSP form factor is the second generation industry standard for pluggable 40Gbps optical transceivers. Size and power dissipation are significantly reduced compared to first generation CFP.
40G QSFP are available as SR4 (Multimode up to 100/150meters) and LR4 (Single Mode up to 10km) version. LR4 version uses 4 x 10Gbps CWDM wavelength in 1270nm-1330nm range and can be combined with SOA for range extension.
