How does the performance of these compare to original brand optics? Are they really just as good but cheaper?

You get the exact same core performance. Our transceivers use premium DFB lasers and PIN receivers, matching the strict hardware specs of OEM parts from Cisco, Juniper, or Dell. It’s a highly cost-effective alternative with absolutely zero compromise on signal integrity.

Can I use standard LC duplex multimode fiber with this module, or do I strictly need single-mode?

You must use Single-Mode Fiber (SMF) paired with an MPO-12/APC angled connector. This module relies on a 1310nm wavelength for up to 10km transmission, meaning standard LC multimode cables are neither physically nor optically compatible.

Our outdoor telecom cabinet gets extremely hot and cold. Is there an industrial wide-temperature version of this 10km module?

This specific LQ-M31100-LR4C operates at commercial temps (0°C to +70°C). While it handles indoor server rooms and standard cooling environments perfectly, for extreme outdoor conditions (-40°C to 85°C), please contact our support. We can custom-build industrial-grade SKUs for your specific cell site backhaul needs.

Will this 100G PSM4 QSFP28 play nice if I mix Cisco Nexus switches on one end and Arista on the other?

Yes, absolutely! The LQ-M31100-LR4C is fully MSA compliant and coded for seamless interoperability. You can comfortably bridge multi-brand setups like Cisco and Arista without getting annoying compatibility alarms on your CLI.

Does this module meet all standard industry protocols for 100G Ethernet?

Yes, it fully complies with QSFP28 MSA, IEEE 802.3bm 100GBASE PSM4, and SFF-8636 standards. It’s rigorously tested to ensure global regulatory and networking compliance across major hardware platforms.
