Our outdoor base station cabinets get incredibly hot in summer and freezing in winter. Can this SFP really handle -40°C?

Yes, this is a true industrial-grade copper SFP! It operates reliably in extreme temperatures ranging from -40°C all the way up to +85°C, making it the perfect choice for harsh environments and outdoor telecom enclosures.

Is this compatible with standard IEEE 802.3ab? Also, does this module support DDM/DOM monitoring features?

It is fully compliant with IEEE STD 802.3 and 802.3ab protocols utilizing an SGMII interface. However, please note that like most 10/100/1000BASE-T copper SFPs, it does not support DDM/DOM diagnostics functionality.

I see it's an SFP module, but does it take standard LC fiber optic cables or just regular RJ45 ethernet?

This specific model is a copper SGMII transceiver, so it features an integrated RJ45 interface. You just plug in standard Cat5, Cat6, or Cat6a UTP cables, offering stable 1G connectivity up to 100 meters without needing any fiber optic lines.

Will this 1000BASE-T SFP work if I mix Cisco core switches with some generic unmanaged switches in our server room?

Yes! The LP-SFP-TMRI module is strictly MSA compliant and features excellent cross-brand OEM compatibility. It auto-negotiates flawlessly with Cisco, Juniper, Arista, and most generic networking gear right out of the box.
