I'm working on establishing a fiber link between your HP ProCurve 2524 and a separate fiber module. So far, it hasn't connected properly—on the TP-Link module it sends data but doesn’t get any back. I've tried various fixes but opened the transceiver to see it operates at 850nm while the switch’s module is rated for 1310nm. This mismatch likely prevents communication. You’re unsure whether you need a 850nm or 1300nm wavelength converter, as your current unit supports only 10/100 and you intended a gigabit solution. The difference in wavelengths does relate to speed—850nm typically supports up to 100 Mbps, while 1310nm can reach gigabit rates. Make sure you purchase the correct wavelength converter for your setup.

Wavelength relates to distance rather than speed directly; it compares single-mode versus multimode wavelengths. Single-mode transmission can travel significantly farther, while multimode is restricted to roughly 500 meters or less based on the data rate. Wavelengths 1310 and 1550 are suited for single-mode fibers, though most modern fiber optics use 1550. Single-mode cables employ a core of about 9 microns, whereas multi-mode uses 50 or 62.5 microns.
