Have you actually tried this? I have personally gotten linkups between
1310 and 1550 GBICs. Just as someone said here before, the receivers are
very wide-band.

1550nm and 1310nm are different colors.

Yes, but if your receiver picks up photons in a range from (just guessing)
1200 to 1700nm light, it doesn't matter.
