Abstract
The utility model discloses a high sensitive TTL optical module from 0 to 50Mb which comprises a transmitting part and a receiving part. The transmitting part comprises a driving circuit and a laser which are connected sequentially; the receiving part comprises a front amplifier, a main amplifier, and a TTL output circuit which are connected sequentially; and the transmitting part and the receiving part adopt a 9 pin package. In the utility model, since the transmitting part and the receiving part which adopt the 9 pin package are used, the speed of the optical module is increased to 50M, and the sensitivity is increased to -31dbm, so that the transmission distance reaches 100KM when the optical module is cooperated with the 232 / 485 data to optical fiber signal.
Description
Technical field
The utility model relates to optical communication technique field, in particular, and the particularly highly sensitive TTL optical module of a kind of 0-50Mb.
?
Background technology
At present, communication is used up in the product of transmitting-receiving unification module, and speed has two defects since 0 product, the one, speed below 10Mb/s, the 2nd, receiving sensitivity lower (18dbm).Speed when it has limited 232/485 supporting with it data and turns fiber-optic signal and the problem of transmission range.Therefore, need to design a kind of novel optical module.
Utility model content
The purpose of this utility model is to have speed and the low technical problem of sensitivity for prior art, and the highly sensitive TTL optical module of a kind of 0-50Mb is provided.
In order to solve problem set forth above, the technical solution adopted in the utility model is: the highly sensitive TTL optical module of a kind of 0-50Mb, radiating portion and receiving unit, described radiating portion comprises drive circuit and the laser connecting successively, described receiving unit comprises successively front amplifier, main amplifier and the TTL output circuit connecting, and described radiating portion and receiving unit all adopt 9 pins encapsulation.
According to a preferred embodiment of the present utility model: described laser is semiconductor laser or light-emitting diode.
According to a preferred embodiment of the present utility model: described radiating portion and receiving unit are integrated on a circuit board.
Compared with prior art, the beneficial effects of the utility model are: owing to having adopted radiating portion and the receiving unit of 9 pin encapsulation, make the speed of optical module bring up to 50M, bring up to-31dbm of sensitivity, the transmission range while making it be that 232/485 data turn fiber-optic signal and coordinate reaches 100KM.

Description of reference numerals: 10, radiating portion, 20, receiving unit, 110, drive circuit, 120, laser, 210, front amplifier, 220, main amplifier, 230, TTL output circuit.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
Consult shown in Fig. 1, the utility model provides the highly sensitive TTL optical module of a kind of 0-50Mb, radiating portion 10 and receiving unit 20, described radiating portion 10 comprises drive circuit 110 and the laser 120 connecting successively, described receiving unit 20 comprises successively front amplifier 210, main amplifier 220 and the TTL output circuit 230 connecting, and described radiating portion 10 and receiving unit 20 all adopt 9 pins encapsulation.
On circuit structure, can select the scheme of drive circuit 110 and laser 120 employing technology; Certainly, also can select front amplifier 210, main amplifier 220 and TTL output circuit 230 to adopt the scheme of prior art.
Wherein, described laser 120 is semiconductor laser or light-emitting diode, and front amplifier 210 is generally selected the amplifier with direct current enlarging function.Further, in order to reduce the volume of whole optical module, in design, adopt radiating portion 10 and receiving unit 20 to be integrated on a circuit board.
The explanation of each pin when following table 1 is receiving unit 20 employing 9 pins encapsulation.
The operation principle of the present embodiment is: the signal of telecommunication of inputting a constant bit rate is processed rear drive laser 120(as semiconductor laser (LD) or light-emitting diode (LED) through the driving chip of the drive circuit 110 of radiating portion 10 inside) launch the modulated light signal of respective rate.Then the light signal of constant bit rate input receiving unit 20 by front amplifier 210, main amplifier 220 after by the signal of telecommunication of TTL output circuit 230 output phase code rates.
After adopting the highly sensitive TTL optical module of 0-50Mb of the present utility model, the technical indicator that following table 2 is whole optical module.
Limiting value index when following table 3 is use.
Above-described embodiment is preferably execution mode of the utility model; but execution mode of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection range of the present utility model.
