10GBASE-LR

10GBASE-LR ("long reach") uses the IEEE 802.3 Clause 49 64B/66B Physical Coding Sublayer (PCS) and 1310 nm lasers. It delivers serialized data over single-mode fiber at a line rate of 10.3125 Gbit/s.

10GBASE-LR has a specified reach of 10 kilometres (6.2 mi), but 10GBASE-LR optical modules can often manage distances of up to 25 kilometres (16 mi) with no data loss.

Fabry–Pérot lasers are commonly used in 10GBASE-LR optical modules. Fabry–Pérot lasers are more expensive than VCSELs but their high power and longer wavelength allow efficient coupling into the small core of single mode fiber over greater distances.
