Questions & Answers

What is the maximum transmission distance of a 40G QSFP+ ER4 module?

The 40G QSFP+ ER4 transceiver is designed for long-reach applications with a transmission distance of up to 40km over single-mode fiber (SMF). This is achieved using four CWDM wavelengths around 1310nm.

Is the 40G QSFP+ ER4 compatible with other 40G formats?

The 40G QSFP+ ER4 is generally not directly compatible with SR4 or LR4 modules due to different wavelength specifications. However, it can work with other ER4 modules from different vendors if they follow the same MSA (Multi-Source Agreement) specifications.

What are the common troubleshooting issues with 40G QSFP+ ER4 modules?

– High bit error rates due to fiber contamination or damage
– Link failures due to incorrect wavelength matching
– Temperature-related performance issues
– Power level fluctuations outside the specification range
