Abstract

An optical fiber transceiver with a detection function for power failure and fiber breaking belongs to an optical fiber transceiver, and solves the problem that an existing optical fiber transceiver cannot give warnings on power failure or fiber breaking. The transceiver comprises a local side optical fiber transceiver and a user side optical fiber transceiver identical in structure, and has the structure as follows: RJ45 transmits ether electric signals to CPLDs (Complex Programmable Logic Device) through an I/O port; the CPLDs collect the signals and then transmit the signals to an optical port PHY through the I/O port; the optical port PHY converts the ether electric signals to optical signals, and emits the optical signals through symmetrical optical ports, wherein differential line terminals of the CPLDs of the local side and user side optical fiber transceivers are connected with a reset chip respectively. The CPLDs of the two optical fiber transceivers are connected with a reset chip respectively, so as to provide detection information for power failure and fiber breaking for the monitoring of lines. When the far end optical fiber transceiver or optical fiber breaks down, the condition can be accurately detected through a web platform in a local side machine room, so as to perform troubleshooting, further, the repair cost is reduced greatly.

A kind of fiber-optic transceiver device with the disconnected fine measuring ability of outage

Technical field

The utility model relates to a kind of fiber optical transceiver, refers in particular to a kind of fiber-optic transceiver device with the disconnected fine measuring ability of outage.

Background technology

The effect of fiber optical transceiver is the paired use by this equipment, the fiber optical transceiver Ethernet electrical signal conversion of local side is become light signal, by the fiber optical transceiver of optical fiber long-distance transmissions to user side, the fiber optical transceiver of user side changes into the signal of telecommunication again with light signal, realizes the long-distance transmissions of ethernet signal.

Referring to Fig. 1, the local side fiber optical transceiver of existing fiber optical transceiver 10 is given CPLD 12 with the ether signal of telecommunication through I/O (I/O) oral instructions by RJ45 mouth 11, CPLD 12 will deliver on the light mouth PHY 13 through the I/O mouth behind the signal collection, light mouth PHY 13 changes into light signal with the ether signal of telecommunication, passes to the user side fiber optical transceiver by symmetrical beam mouth 14.The user side fiber optical transceiver changes into the signal of telecommunication again with light signal, realizes the long-distance transmissions of ethernet signal.The paired use of the fiber optical transceiver by local side and user side reaches the two-way transmission of local side and user side data.

The fiber optical transceiver of said structure does not possess alarm function to faults such as the outage that takes place in using or disconnected fibres, even therefore local side machine room attendant finds that fault has appearred in the work of fiber optical transceiver, can not determine the reason of user side fault accurately, this brings certain degree of difficulty to maintenance, and maintenance cost also so very high.

The utility model content

The purpose of this utility model is in order to solve the problem that above-mentioned prior art exists, provide a kind of the distal fiber transceiver outage is taken place or disconnectedly can send alarm when fine, to realize far-end the break fiber-optic transceiver device of fine measuring ability of the band outage that just can accurately judge its reason that breaks down.

The purpose of this utility model is achieved through the following technical solutions:

A kind of fiber-optic transceiver device with the disconnected fine measuring ability of outage, comprise local side and user side fiber optical transceiver that structure is identical, its structure is: the RJ45 mouth is given CPLD with the ether signal of telecommunication through the I/O oral instructions, CPLD delivers on the light mouth PHY through the I/O mouth after with signal collection, light mouth PHY changes into light signal with the ether signal of telecommunication, and send light signal by the symmetrical beam mouth, wherein:

On the fork separated time terminal of the CPLD of local side and user side fiber optical transceiver, connect the chip that resets respectively.

The described chip that resets adopts the IMP809L chip.

The beneficial effects of the utility model:

In the fiber-optic transceiver device of the disconnected fine measuring ability of band outage of the present utility model, on the CPLD of local side and user side fiber optical transceiver, connect 1 chip that resets respectively, for path monitoring provides a kind of outage fine detection information of breaking, when distal fiber transceiver or optical fiber break down, can accurately distinguish by network management platform at the local side machine room, get rid of so that carry out fault, significantly reduced maintenance cost, satisfied complete monitoring and safeguarded simple requirement.In addition, this device has reduced investment and construction period that prior art is transformed owing to do not need to lay in addition new optical cable or other circuit.
