Product Description

QSFP+ 40G ER4 40km 1270nm/1290nm/1310nm/1330nm CWDM SMF Optical Transceiver Module for Ethernet and Date Center




  • Operating case temperature 0°C to +70°C
  • 3.3V power supply
  • RoHS 6 compliant(lead free)
  • Up to 11.2Gbps per channel,supports 39.8Gb/s to 44.6Gb/s aggregate bit rates
  • QSFP+ MSA compliant
  • High Sensitivity APD-TIA with optical DEMUX
  • Up to 40km reach over standard single mode fiber
  • Hot pluggable electrical interface
  • Compliant to IEEE 802.3ba specification for 40GBASE-ER4 links
  • 4 CWDM un-cooled DFB lasers, using ITU G.694.2 wavelength grid at 1271, 1291, 1311 and 1331nm



The 40GBASE-ER4 QSFP Module supports link lengths up to 40km over G.652 single-mode fiber with duplex LC connectors. The 40GE or OTU3 signal is carried over four wavelengths in the 1310nm range. Multiplexing and demultiplexing of the four wavelengths are managed within the device.

Note4: Average launch power, each lane (min) is informative and not the principal indicator of signal strength. A

transmitter with launch power below this value cannot be compliant; however, a value above this does not ensure


Note5: Even if the TDP < 0.8dB, the OMA (min) must exceed this value.

Note6: Filtered, measured with a PRBS 231-1 test pattern @10.3Gbps.

Note7: The receiver shall be able to tolerate, without damage, continuous exposure to an optical input signal

having this average power level.

Note8: Minimum average optical power measured at BER less than 1E-12, with a 231-1 PRBS.

Note9: Measured with conformance test signal at TP3 for BER=1E-12.

Note10: Vertical eye closure penalty, stressed eye J2 Jitter, stressed eye J9 Jitter are test conditions for

measuring stressed receiver sensitivity. They are not characteristics of the receiver.
