A wideband optical module includes a downward wideband light source for generating downward light, an upward wideband light source for generating upward light, a first circulator including a first to a third port for outputting multiplexed downward optical signals to the second port and for outputting multiplexed upward optical signals to the first port, a second circulator including a first to a third port for outputting multiplexed upward optical signals to the second port and for outputting multiplexed downward optical signals to the first port, a first optical coupler connected to the third port of the first circulator and the second port of the second circulator for outputting the downward light to the third port of the first circulator, and a second optical coupler connected to the second port of the first circulator and the third port of the second circulator for outputting the upward light to the third port of the second circulator.
