Let me make sure Cisco's SFP module, GLC-FE-100FX.
While the GLC-FE-100FX specification states MMF, the wavelength is 1310nm.
My understanding is that1310nm is generally recognized as a single specification.
Do you see any problems if I use a common MMF 850/1300nm optical cable for connection?
Thank you very much.

According to the data sheet (link below), and referring to Table 1, the GLC-FE-100FX module is 1300nm MMF.
Good luck.

The following material that tells us about GLC-FE-100FX is written as 1310nm instead of 1300nm.https://www.cisco.com/web/JP/product/hs/ifmodule/sfps/prodlit/pdf/sfpfesp_ds.pdf
As written in Japanese local language, sorry if this may cause any inconvenient for you, Tom, and other global users. I thought it might be probably a typo.

Having authored many technical documents myself, it is difficult to get the documents 100% correct.
The IEEE 802.3 specification outlines it as a multimode interface. The operating wavelength is specified as 1270 through 1380 nm, so technically, therefore, the wavelength could be 1300 or 1310, but multimode fiber.
