Description
Technical field
The utility model relates to a kind of optical receiver, relates in particular to a kind of light signal input state display for optical receiver.
Background technology
At present, optical fiber communication is widely applied in broadcast, TV, network, transportation and other fields.In Fiber-optic Communication Projects implementation process, mostly adopt optical receiver realize photosignal conversion and process.But optical receiver is the general whether device of input communication device interior of judgement and identification light signal that lacks in the time of receiving optical signals, most of time, can only rely on workmen to pass through naked eyes and directly observe whether access communications equipment of light signal, this mode is easy to produce erroneous judgement and efficiency of construction, and is also difficult to realize the regular maintenance and management after having constructed.
Summary of the invention
The utility model can only lean on the whether shortcoming of input communication device interior of human eye judgement and identification light signal when the optical receiver receiving optical signals for prior art, a kind of simple in structure on optical receiver and light signal input state display that cost is low of being located at is provided.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of light signal input state display for optical receiver, comprise and be embedded the photoelectric conversion module in optical receiver and the alarm display apparatus being connected with photoelectric conversion module, photoelectric conversion module comprises the operation amplifier comparator circuit of chip and chip, on photoelectric conversion module, be provided with light signal input interface, light signal is from light signal input interface input optical receiver, light signal is converted to the signal of telecommunication through photoelectric conversion module, and alarm display apparatus is LED alarm lamp.Be-7～+ 2dB from the luminous power of light signal input interface input, LED alarm lamp shows green, represents that light signal is normal; From the be less than-7dB of luminous power of light signal input interface input, LED alarm lamp shows red, and red early warning represents that the light signal of input is too little, lower than normal value, should check whether fibre circuit has gone wrong; From the be greater than+2dB of luminous power of light signal input interface input, LED alarm lamp shows yellow, and yellow early warning represents that the light signal of input is too large, exceeds normal value, can suitably reduce the luminous power of an input, until LED alarm lamp shows green.
As preferably, LED alarm lamp exposes at optical receiver shell, is convenient to observe optical receiver and receives the state of light signal.
As preferably, on optical receiver shell, be provided with the LED light being connected with photoelectric conversion module, LED light is 10 barcode LEDs,-7～+ 2dB reference optical power is divided into 10 power sections among a small circle, the maximum power value of each section of power is among a small circle 1dB, and each LED light is for showing and the corresponding optical power value of power section among a small circle.When light signal is from light signal input interface input optical receiver, LED light shows this optical power value.
As preferably, on photoelectric conversion module, be also provided with electrical signal output interface, the signal of telecommunication is exported from electrical signal output interface.
The utility model is owing to having adopted above technical scheme, there is significant technique effect: adopt the light signal input state display being located on optical receiver, by photoelectric conversion module and LED alarm lamp, state can observe directly light signal input optical receiver time, this light signal input state price display unit is cheap and practical.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model light signal input state display embodiment.
Fig. 2 is the circuit theory diagrams of the operation amplifier comparator circuit embodiment of the chip of Fig. 1.
The toponym that in accompanying drawing, each number designation refers to is as follows: wherein 1-optical receiver, 2-photoelectric conversion module, 3-LED light, 4-LED alarm lamp, 5-chip, 21-light signal input interface, 22-electrical signal output interface.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
Embodiment 1
A kind of light signal input state display for optical receiver, as shown in Figure 1, comprise and be embedded the photoelectric conversion module in optical receiver 12 and the alarm display apparatus being connected with photoelectric conversion module 2, alarm display apparatus is LED alarm lamp 4, and LED alarm lamp 4 exposes at optical receiver 1 shell; Photoelectric conversion module 2 comprises the operation amplifier comparator circuit of chip 5 and chip as shown in Figure 25, on photoelectric conversion module 2, be provided with light signal input interface 21 and electrical signal output interface 22, light signal is inputted optical receiver 1 from light signal input interface 21, light signal is converted to the signal of telecommunication through photoelectric conversion module 2, from electrical signal output interface 22 output electrical signals.
On optical receiver 1 shell, be provided with the LED light 3 being connected with photoelectric conversion module 2, LED light 3 is 10 barcode LEDs,-7～+ 2dB reference optical power is divided into 10 power sections among a small circle, the maximum power value of each section of power is among a small circle 1dB, and each LED light 3 is for showing and the corresponding optical power value of power section among a small circle.When light signal is from light signal input interface 21 is inputted optical receiver 1, if the optical power value showing in LED light 3 is within the scope of-7～+ 2dB, LED alarm lamp 4 shows green, represent that light signal is normal, light signal carries out this light signal through photoelectric conversion module 2, after the processing of sample of signal, conversion and amplification etc., being converted to the signal of telecommunication simultaneously; If the be less than-7dB of optical power value showing in LED light 3, LED alarm lamp 4 shows red, and red early warning represents that the light signal of input is too little, lower than normal value, should check whether fibre circuit has gone wrong; If the be greater than+2dB of optical power value showing in LED light 3, LED alarm lamp 4 shows yellow, and yellow early warning represents that the light signal of input is too large, exceeds normal value, can suitably reduce the luminous power of an input, until LED alarm lamp 4 shows green.
