<p>PROBLEM TO BE SOLVED: To provide a parallel optical communication module that can simplify wiring on a printed board.SOLUTION: A parallel optical communication module 100 includes a module board 1, and on an electrode surface 13 of the module board 1, a plurality of high-speed signal electrodes 6 and a plurality of high-frequency wave ground electrodes 11 are arranged such that they form a first square lattice 28. The high-speed signal electrodes 6 are not situated on lattice points 30g of the outermost periphery of the electrode surface 13, and are positive phase signal electrodes 15 or reversed phase signal electrodes 16. Both form a pair of high-speed signal electrodes 26 by being arranged on lattice points 30a, 30b next to each other in the direction inclined at 45 degrees from a lattice line 29 of the first square lattice 28. A lattice point on a straight line 34 in one side relative to a line segment 27 among a perpendicular bisector 24 of the line segment 27 connecting both is an electrode unoccupied lattice point 35. The high-frequency wave ground electrodes 11 are arranged on lattice points excluding the electrode unoccupied lattice point 35 among adjacent lattice points around the pair of high-speed signal electrodes 26.</p> |
