LINK-PP LS-SM3110-20C 10G SFP+ FAQ

Here are answers to some frequently asked questions regarding the deployment and specifications of the LS-SM3110-20C 10G SFP+ module.

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.
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).
The LS-SM3110-20C requires standard Single-Mode Fiber (SMF), typically 9/125um OS1 or OS2, terminated with a Duplex LC connector.
The module is highly compatible with most standard networking equipment from brands like Cisco, Arista, and Juniper, thanks to its strict MSA standard programming.
