Description
Technical field
The present invention relates to the fibre optic transmission equipment of a kind of radar system, particularly relate to a kind of miniaturization multichannel two-way signaling fiber-optic transfer
Assembly.
Background technology
Along with the development of Radar Technology, while improving constantly performance, radar just develops towards the direction of miniaturization, separately
On the one hand the required data volume processed and transmit of radar system is increasing, and signal way also gets more and more, and has analogue signal, number
The number of it is believed that, pulse signal, these signal kinds are different, transfer rate is different, and radar system is the most different to the requirement of these signals.
The increase of signal way makes the volume of radar system become big weight to become weight, and this is that airborne, shipborne radar institute is unacceptable, with
Traditional cable communication is compared fiber optic communication and is had the remarkable advantages such as transfer rate is fast, volume is little, lightweight, capacity of resisting disturbance is strong.
The fiber optic communication application in commercial market has driven it in the application of military industry field with development, and the signal transmission form of radar system is also
Gradually changed to light by electricity, and the optical module of existing transmission signal is broadly divided into integration of compact optical module and according to actual needs
The multipath signal propagation optical module developed.Optical module SFP, SFP+, XFP, SFF that integration of compact optical module is the most currently marketed
Deng, concrete size is as follows:
SFP:57.2mm × 13.7mm × 12.7mm
SFP+:56.5mm × 14.0mm × 12.1mm
XFP:77.8mm × 22.2mm × 16.1mm
SFF:48.5mm × 13.2mm × 10.8mm
Optical module described above not only volume is big but also function singleness, it is impossible to realize receiving simultaneously and sending multichannel data, with often
As a example by SFP optical module, although this optical module has the function sending and receiving, but can only send and receive a circuit-switched data, if
Wanting bi-directionally sent 8 circuit-switched data, then need 16 SFP optical modules to use parallel and need 16 Transmission Fibers, its volume is thunder
Reach system institute insupportable.The existing commercially available optical module that can simultaneously transmit multichannel data, its body as a example by 8 circuit-switched data optical transmitter and receivers
Long-pending minimum: 175mm × 150mm × 75mm, the volume of the type product also cannot meet the requirement of radar system miniaturization, and
The type product cannot realize the transmitted in both directions utilizing an optical fiber to realize 8 circuit-switched data, and this radar system type products can pass in addition
Defeated data signal type is common RS232, RS485, low speed switch amount signal, it is impossible to meet the high speed needed for radar system,
The demand that signal kinds is complicated and changeable.As can be seen here, for meeting the requirement of radar system two-forty, multi-channel data transmission, little chi
The development demand of very little miniaturization optical transceiver module is extremely urgent.
Small optical transceiving modular is the Novel Optoelectronic Device optical mode that will launch, receiving unit is encapsulated in same housing together
Block.Optical module is divided into single-mode optical module and multi-mode optical module, then includes optical secondary module (Optical on integral product framework
Subassembly；TOSA, ROSA), electronics secondary module (Electrical Subassembly；And mechanical hull three is big ESA)
Part.Its circuit board all uses straight plate form, and laser instrument and detector are the optical secondary module of band ceramic insertion core, and electrical interface is adopted
Be golden finger mode, controller, limiting amplifier, laser driver etc. are the integrated chip of common IC, and this general light
Module chip dispersion, spacing are relatively big, use 2 optical modules to realize transmission and the reception of optical signal, whole optical module volume greatly,
Function singleness.
And the most commercially available video optical multiplexer of photovoltaic that multichannel data can be transmitted, audio frequency optical transmitter and receiver and data optical receiver either volume
Or the kind of transmission signal the most all cannot meet radar system to volume and the requirement of signal kinds, no longer describes at this.Root
According to the particular/special requirement of radar system, have developed some photovoltaic that can transmit multichannel data.Existing can transmit analog voltage simultaneously
The optical module of signal and pulse signal uses voltage signal and pulse signal individually transmits, i.e. voltage signal such as 4 road electricity
Pressure signal is transmitted by a road optical channel and pulse signal and other data signals are transmitted by other optical channel,
Have a few circuit-switched data signal just with several roads optical channel, same You Ji road pulse signal with regard to several roads optical channel, its theory diagram such as Fig. 1
Shown in, this multichannel data fiber-optic transfer assembly transmitting terminal sends 5 road signals, respectively 4 road analog voltage signals and the event of 1 tunnel altogether
Barrier protection signal.4 road analog voltage signals are transformed to data signal by parameter acquisition, are transformed to 1 circuit-switched data through signal processing
Signal is transmitted through an optical fiber, and error protection signal is that data signal passes through single light after input circuit shaping is amplified
Passage realizes transmission；Receiving terminal sends 3 road signals, respectively 2 road pulse signals and 1 tunnel control signal altogether.2 tunnel pulse letters
Number realizing transmission by 2 optical-fibre channels, 1 tunnel control signal realizes transmission by an other road optical channel.As shown in fig. 1,
Although transmitting terminal and receiving terminal can send data and receive data, but send and receive and can not be realized by an optical fiber, send
End has used 2 light emission modules, 3 Optical Receivers, and corresponding receiving terminal has then used 2 Optical Receivers, 3 light emission
Module.Transmitting terminal and receiving terminal need to realize transmitted in both directions with 5 optical fiber.
The product design corresponding with Fig. 1 is as in figure 2 it is shown, the length, width and height size of this multichannel data fiber-optic transfer assembly is respectively as follows:
69.5mm×59.6mm×14.4mm.This multichannel data fiber-optic transfer assembly can realize 4 road analog voltage signals, 2 tunnel pulse letters
Number, the transmission of 2 circuit-switched data signals, applied in high_voltage isolation in the detection of radar travelling-wave tube high pressure, but this assembly is the most front
Described in face, it is impossible to realize the multichannel data transmitted in both directions by an optical fiber, and this assembly volume cannot meet more greatly radar system
The needs of the small-volume and multifunctional required by development.
