Abstract

The utility model discloses a transmission luminous power and the receipt luminous power while calibrating device of SFP optical module, including light source module, SFP module, host computer, optical power meter and optical divider, optical power meter passes through the RS232 serial port connection host computer, and the host computer is still through the USB interface connection SFP module testing board, light source module sends fixed light, then through optical divider share two tunnel, sends into SFP module receiving terminal all the way, and optical power meter is sent to on another way, and SFP module transmitting terminal still is connected to optical power meter. The utility model discloses a calibration of transmission luminous power and receipt luminous power calibration flow of SFP module are accomplished simultaneously to the host computer. At this in -process, all accomplish by the host computer automation, the manufacturing worker only need to be changed await measuring the SFP module can, the error not only can effectual reduction brought by manual operation, promotion production efficiency that more can be great.

Description

A kind of utilizing emitted light power of SFP optical module and received optical power calibrating installation
Technical field
The utility model relates to a kind of calibrating installation, specifically a kind of utilizing emitted light power of SFP optical module and received optical power calibrating installation.
Background technology
Existing SFP calibrating mode is that optical module transmitting terminal to be measured is received hand-held optical power gauge, therefrom read current optical power value, host computer is utilized to write values into inside modules, then use the module of another fixed light power as light source, test out the luminous power of light source, be sent to the receiving end of optical module to be measured by optical fiber, then by inner for the value host computer writing module just now reading light source, so just complete the calibration process of module utilizing emitted light power and received optical power.
In a calibration process, manual operation can cause error to increase, and cannot ensure that whether the value of modular calibration is correct, manual process more in addition can increase production procedure and time, is unfavorable for batch production.
Utility model content
The purpose of this utility model is the utilizing emitted light power and the received optical power calibrating installation that provide a kind of SFP optical module, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of utilizing emitted light power of SFP optical module and received optical power calibrating installation, comprise light source module, SFP module, host computer, light power meter and optical branching device, described light power meter connects host computer by RS232 serial ports, host computer also connects SFP module testing plate by USB interface, described light source module sends fixing light, is then divided into two-way through optical branching device, and SFP module receiving end is sent on a road, light power meter is sent on another road to, and SFP module transmitting terminal is also connected to light power meter.
As preferred version of the present utility model: the calibration that automatically can complete SFP module utilizing emitted light power and received optical power without the need to manual operation.
Compared with prior art, the beneficial effects of the utility model are: the utility model completes the utilizing emitted light calibration of power of SFP module by host computer simultaneously and received optical power calibrates flow process.In this process, be all come by host computer robotization, Manufacturing Worker only needs to change module to be measured, not only can effectively reduce the error brought by manual operation, more can improving production efficiency greatly.
Accompanying drawing explanation
Fig. 1 is the utilizing emitted light power of SFP optical module and the structured flowchart of received optical power calibrating installation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of utilizing emitted light power of SFP optical module and received optical power calibrating installation, comprise light source module, SFP module, host computer, light power meter and optical branching device, described light power meter connects host computer by RS232 serial ports, host computer also connects SFP module testing plate by USB interface, described light source module sends fixing light, then two-way is divided into through optical branching device, SFP module receiving end is sent on one tunnel, light power meter is sent on another road to, and SFP module transmitting terminal is also connected to light power meter.
Principle of work of the present utility model is: the present invention sends fixing light by light source, then two-way is divided into through optical branching device, one tunnel is sent into SFP module RX to be measured and is held, light power meter is sent on another road to, make SFP module RX to be measured hold the luminous power 1 received identical with the luminous power 2 that light power meter receives, would not error be caused like this in subsequent calibration procedure.Meanwhile the transmitting terminal of SFP module to be measured is connected to another interface of light power meter, is used for measuring the luminous power that SFP module to be measured sends.
And power meter is connected on PC by RS232 serial ports, the utilizing emitted light power that the host computer of PC end is measured by the reading light power meter that RS232 is real-time and received optical power two values, and these two values are write in SFP module to be measured by USB interface.
Host computer is according to the value of utilizing emitted light power and received optical power, by ADCcal=slope*ADCraw+offset formula, calculate corresponding slope and offset value, be sent to SFP module chip by USB more inner, this completes the utilizing emitted light power of SFP module and the calibration of received optical power.
