Abstract
Reflections from connector end faces located near the transmitter generate intensity noise in the laser output which was found to be a function of the resonance frequency of the laser. The intensity noise introduces only an insignificant power penalty for buried-heterostructure lasers operating with a resonance frequency above 4 GHz, but could make transmission impossible in certain types of stripe geometry lasers operating with a resonance frequency below 3 GHz. Another potential system degradation may be due to modal noise which occurs mostly in laser pigtails or short jumper cables with overmoded single-mode fibers carrying both the fundamental and the higher order modes. The power penalty due to modal noise becomes negligible when the fiber section between two connectors is sufficiently long, or is deployed with a bend to sufficiently attenuate the LP11 mode.
