FIBER OPTIC TELECOMMUNICATIONS CARD WITH ENERGY LEVEL MONITORING
1-17. -17. (canceled)
A transceiver card for a telecommunications box for transmitting data over a first optical fiber and receiving data over a second optical fiber. The card has transmitter for transmitting data over the first optical fiber, the transmitter having a laser and a modulator, a fiber output optically connected to the laser for connecting the first optical fiber to the card, a fiber input for connecting the second optical fiber to the card, a receiver optically connected to the fiber input for receiving data from the second optical fiber, and an OTDR optically connected between the transmitter and the fiber output or between the receiver and the fiber input. An energy level detector is also provided between the receiver and the fiber input.

35. A telecommunications method, comprising:
receiving, by an optical receiver affixed to a telecommunications card and optically connected to an optical fiber, an optical data signal from the optical fiber; monitoring, by an energy level detector affixed to the telecommunications card and optically coupled to the optical fiber upstream from the optical receiver, an energy level of the optical data signal; providing a first reference signal corresponding to a first energy level threshold and a second reference signal corresponding to a second energy level threshold; and generating an alarm, based on the energy level of the optical data signal, the first reference signal and the second reference signal, responsive to detecting either; the energy level exceeding the first energy level threshold;
the energy level below the second energy level threshold.
