英文摘要	A multi-channel transmitter optical subassembly (TOSA) with an off-center fiber in an optical coupling is disclosed, and can provide passive compensation for beam displacement introduced by optical isolators. The optical coupling receptacle can include an optical isolator configured to receive a focused light beam from a focus lens within the TOSA. The optical coupling receptacle may be offset such that a center line of the focused light beam entering the optical isolator is offset from a center line of a fiber within optical coupling receptacle. Thus the optical isolator receives the focused light beam from the focus lens and introduces beam displacement such that an optical signal is launched generally along a center line of the fiber. Thus the expected beam displacement introduced by the optical isolator is eliminated or otherwise mitigated by the offset between a center line of the fiber and a center position of the focus lens.
