  • Why do optical modules get hot

    Why do optical modules get hot

    Optical transceivers generate heat during operation due to its electrical and optical components. If this heat is not dissipated efficiently, it can lead to increased temperature levels within the transceiver. High temperatures can adversely affect the reliability of optical. High temperature impacts several internal parts in different ways: Laser diodes (DFB, VCSEL): Output power and wavelength shift with temperature.
