40GBASE-ER4 QSFP+ specifications
The following table lists the transmitter and receiver specifications for the 40GBASE-ER4 QSFP+
transceiver with corresponding wavelengths. The reach for this QSFP+ transceiver is up to 40
kilometers. The part number is AA1404003-E6.
40GBASE-ER4 QSFP+
Warning:
A direct connection from Tx to Rx can damage the receiver. If you use a short jumper, short
fiber cable, or loopback cable, you must ensure the following to avoid permanent receiver
damage:
You must have an attenuator that results in a minimum of 9 dB insertion loss between the transmitter
and receiver.
The cable plant must have a minimum of 9 dB insertion loss between the transmitter and receiver
for correct operation. If the fiber cable does not have this much loss, use an attenuator to meet the 9
dB requirement. No attenuator is needed if insertion loss is at least 9 dB.
