1000Base-LX SMF
Experts;
We are going to be getting 1000Base-LX from provider but customer is all cabled up w/ MMF wiring and MMD SFP on router, the device is at around 100Mts from the demarc. Can you please shine some light if this setup will work, the change is going to cost and was wondering if there is a real need for a change?
Thanks;

100M is child's play for MMF

So, MMF setup will work for 1000Base-LX optical gigabit solution that uses long wavelength Laser?
1000BASE-LX
1000BASE-LX is an optical fiber Gigabit Ethernet standard specified in IEEE 802.3 Clause 38 which uses a long wavelength laser (1,270–1,355 nm), and a maximum RMS spectral width of 4 nm.
1000BASE-LX is specified to work over a distance of up to 5 km over 10 µm single-mode fiber.
1000BASE-LX can also run over all common types of multi-mode fiber with a maximum segment length of 550 m. For link distances greater than 300 m, the use of a special launch conditioning patch cord may be required.[10] This launches the laser at a precise offset from the center of the fiber which causes it to spread across the diameter of the fiber core, reducing the effect known as differential mode delay which occurs when the laser couples onto only a small number of available modes in multi-mode fiber.

1000BASE-LX is specified to work over a distance of up to 5 km over 10 µm single-mode fiber.
The question is if the distance less, can it work MMF fiber?

Thanks , I did not read the whole paragraph that well.
