	We study the spatial behavior of coherency and magnetic field in a two-orbital superconductor. The superconducting phase transition is caused here by the on-site intra-orbital attractions (negative-U Hubbard model) and interorbital pair-transfer interaction. We find the critical (diverging at inline image) and noncritical (remaining finite) coherence lengths and magnetic field penetration depth for various values of hopping integrals and the strengths of intra-orbital attractions. Numerical results have been obtained for a two-dimensional square lattice. The role of the interorbital proximity effect was also discussed.
