What type of fiber and maximum distance does this transceiver support?

It is designed for Single-Mode Fiber (SMF) using a Duplex LC connector and supports stable 10Gbps data transmission up to 2 kilometers.

Is this industrial module compatible with standard commercial switches?

Yes, it is fully MSA compliant and will work seamlessly in both industrial switches and standard commercial network equipment from major brands.

Does the SFP-10GLRL-31-I support real-time network monitoring?

Yes, it includes Digital Optical Monitoring (DOM), which allows administrators to track critical operational data such as temperature, voltage, and optical power levels in real time.

What fiber type and connector does this transceiver require?

The module uses Duplex LC connectors and is designed for the specified single-mode or multimode fiber type listed in the product specifications.

Is an industrial temperature version available for outdoor cabinets?

Yes. Industrial-grade versions with extended operating temperatures are available for factory automation, telecom, and outdoor networking applications.

Does it support standard telecom and Ethernet protocols?

Yes. The transceiver complies with MSA requirements and supports standard Ethernet networking applications as well as common telecom deployment scenarios.

Will this module work with Cisco, HPE Aruba, and Juniper switches?

Yes. It supports multi-vendor compatibility and can be programmed for Cisco, Aruba, Juniper, Dell, Ubiquiti, Netgear, and other major platforms.
