What is the maximum transmission distance of the SFP-10GLR-31 module?

This module is designed to support high-speed 10Gbps data transmission up to a maximum distance of 10 kilometers over Single-Mode Fiber (SMF).

Is the SFP-10GLR-31 compatible with standard network switches like Cisco or Juniper?

Yes, the transceiver is fully MSA compliant, ensuring reliable, plug-and-play compatibility with major networking brands including Cisco, Juniper, Arista, and Ubiquiti.

Does this 10km SFP+ module support Digital Optical Monitoring (DOM)?

Yes, it features integrated DOM capabilities, allowing network administrators to monitor real-time parameters such as temperature, optical output power, and receiver sensitivity.

What wavelength does this transceiver operate on?

The SFP-10GLR-31 operates at a standard 1310nm wavelength, which is optimized for minimizing dispersion over 10km single-mode fiber links.

Are these strictly for 10G Ethernet, or can they auto-negotiate and support CPRI/OBSAI protocols for our telecom tower setup?

These modules are incredibly versatile! Besides standard 10GBASE-LR Ethernet, they natively support CPRI and OBSAI protocols, making them an excellent choice for telecom base station backhaul, remote radio unit (RRU) connections, and standard enterprise switching.

Hey, will these 10G SFP+ modules work with our older Cisco Catalyst gear and newer Arista switches without throwing unsupported transceiver errors?

Yes! These 10GBASE-LR transceivers are fully MSA compliant and rigorously tested for OEM compatibility. They plug and play perfectly with Cisco, Arista, Juniper, and other major brands without triggering any "unsupported transceiver" warnings.

Just to double-check, do I need OS2 single-mode fiber for these, or can I use my existing OM3 multimode patch cords for a short 1km run?

This specific module (1310nm, 10km) is designed strictly for Single-Mode Fiber (SMF) such as OS1 or OS2 using a Duplex LC connector. Multimode fiber (OM3/OM4) is not physically compatible with this optical spec, even for short distances.

We are planning a massive data center upgrade and need about 200 of these 1310nm 10km optics. Do you offer any discount for bulk NOC deployment?

Absolutely. We offer tiered B2B pricing for wholesale and batch deployments. Please reach out to our enterprise sales team directly with your required quantity, and we’ll provide a custom discounted quote to fit your project budget.

I need to deploy these in an outdoor street cabinet for cell site backhaul. Can the module survive freezing winters and extreme summer heat?

Yes, we offer both commercial and industrial temperature versions. For outdoor cabinets or unconditioned edge environments, simply select the Industrial Temp (-40°C to 85°C) option to ensure stable Tx/Rx performance and continuous DDM monitoring in harsh weather.
