The unit may be ordered with optional optical transmitters and receivers. The laser options
range from the standard -7.5dBm 1310nm to the CWDM units. The receivers may be either
HD, which will receive both HD and SD data rates; or SD which has a multimode fiber.

The module has signal generators for audio and video for test and line up applications. The
internal video generator may be used as a fall-back source that is used if the both the
electrical and the optical input signals fail. This allows uninterrupted transmission of
embedded audio.
