Do these 40G modules meet CE and standard IEEE specs for EU deployments?

100%. They are fully compliant with the IEEE 802.3ba 40GBASE-LR4 standard and QSFP+ MSA. For EU compliance, they hold CE, RoHS, and REACH certifications, so your compliance team has nothing to worry about.

The connector says MPO-12/APC. Do I strictly need an APC patch cable for this 10km run, or can I get away with a standard UPC single-mode?

You definitely want to stick with MPO-12/APC single-mode fiber here. The angled polish (APC) minimizes back reflection (return loss), which is crucial for maintaining signal integrity over a 10km run. Using UPC will cause signal degradation and high CRC errors over distance.

Hello, we're running a mixed environment with Cisco Nexus and some Arista spines. Will this LQ-M3140-LR4C optic play nice with both out of the box, or do we need specific firmware for each?

They work right out of the box! These are fully MSA compliant and rigorously tested for multi-vendor interoperability. You can plug them into your Cisco and Arista gear without worrying about any "unsupported transceiver" errors.

What is FEC (Forward Error Correction)?

FEC (Forward Error Correction) is an error correction technique todetect and correct a limited number of errors in transmitted data without the need for retransmission. It works by adding redundant bits to a bitstream to help the decoder odetect and correct some transmission errors without the need for retransmission. This function needs to be turned on by the transmission device.
