We developed a new MU-type fixed optical attenuator for 4.5 mm pitch packaging. We succeeded in miniaturizing the attenuator by adopting a design employing an MUJ plug. This fixed optical attenuator achieved a tensile strength of greater than 70 N, which is the same as that of a conventional fixed optical attenuator, and also exhibited good environmental and mechanical durability. The new fixed optical attenuator can be used in existing communication devices in which 4.5 mm pitch MU adaptors are already installed.
