Does this module require optical attenuators for shorter fiber runs?

While designed for 20km, the 1310nm laser's output power is generally safe for shorter links (e.g., 2km to 5km) without attenuators, but it is always recommended to check receive power levels via DOM to avoid receiver saturation on very short patch cables.

Can I connect this 20km module to a 10km module on the other end?

Yes, as long as both modules operate at 10Gbps over a 1310nm wavelength on Single-Mode Fiber, they will communicate, provided the total link distance does not exceed the lower module's optical budget (10km).

What type of fiber cable is compatible?

The UF-SM20-10G requires standard Single-Mode Fiber (SMF), typically 9/125um OS1 or OS2, terminated with a Duplex LC connector.

Is it compatible with my specific brand of switch?

The module is highly compatible with most standard networking equipment from brands like Cisco, Arista, and Juniper, thanks to its strict MSA standard programming.

I need to deploy these in an outdoor street cabinet. Can this module survive extreme temperatures, and do I need OS2 single-mode fiber for a 15km run?

This specific LS-SM3110-20C model is commercial temp (0°C to 70°C). For unconditioned outdoor cabinets, we highly recommend selecting our Industrial Temp version (-40°C to 85°C) for stable Tx/Rx performance. And yes, a 15km run requires Single-Mode Fiber (SMF) like OS1 or OS2 using a Duplex LC connector.

Hey guys, will these 10G SFP+ modules work with my older Cisco Catalyst switches and newer Arista gear? Also, do you offer any discount for bulk NOC deployment?

Yes! These transceivers are fully MSA compliant and rigorously tested for OEM compatibility, plugging seamlessly into Cisco, Arista, Juniper, and other major brands. We absolutely offer tiered B2B pricing for wholesale and batch deployments. Please reach out to our enterprise sales team for a custom quote.

Are these strictly for standard 10GBASE-LR Ethernet, or can they auto-negotiate and support CPRI/eCPRI protocols for our telecom tower setup?

These modules are incredibly versatile. In addition to standard 10G Ethernet, they natively support CPRI and eCPRI protocols. This makes them a perfect, low-latency choice for telecom base station backhaul, remote radio units (RRU), and enterprise switching alike.

Tested these in an outdoor cabinet for cell site backhaul. Tx/Rx light levels are optimal over a 15km SMF run using the eCPRI protocol. Definitely buying more for telecom upgrades.
