Abstract
The invention provides a unidirectional optical fiber data alarm method. A connection state of an optical fiber link is detected in real time; when it is detected that an anomaly occurs in the optical fiber link, a microprocessing unit sets a local optical fiber port to be in a loopback state by force through an SMI (Serial Management Interface) until a fault port is recovered to normal; and moreover, alarm data is sent to an opposite side through the local optical fiber port. According to the method, when the connection anomaly occurs in the optical fiber port, the optical fiber port is enabled to enter the local loopback state; the connection is reserved; the alarm data is sent to an opposite side node through the optical fiber port; the alarm mode is simple and effective; the defect in the prior art is improved; a new method is provided for alarm of the optical fiber connection anomaly; the optical fiber connection anomaly condition can be alarmed timely; and a maintainer can discover the problem timely and carries out follow-up maintenance.
Description
Technical field
The present invention relates to technical field of optical fiber communication, be specifically related to a kind of one-way optical fiber data alarm method.
Background technology
At present in optical fiber telecommunications system, Ethernet point-to-point transmission many employings fiber optical transceiver (MC, Media converter), fiber optical transceiver includes fiber port and twisted-pair feeder port, using point-to-point mode optical fiber to connect by described fiber port between fiber optical transceiver, IEEE802.3 standard (100Base-FX or 1000Base-X) is followed in the connection between two nodes.The fiber port of each node includes receiving terminal (RX) and transmitting terminal (TX).When a node does not receives the optical signal that peer node is sent, the fiber port connection of this node can disconnect, and causes local node abnormal conditions cannot be informed peer node.Current commonly used LFP (Link Fault Pass through) coordinates FEF (Far end
Fault pattern) technology realizes, when there is connecting fault in LFP technical support optical fiber link, can the mandatory light mouth network interface Close All by two nodes connected, to point out current node network failure；Far end fault pattern technology can point out the transmitting signal of peer node to go out active.
LFP and FEF both technology are all based on physical layer, remind attendant that equipment breaks down by the light on and off of the working station indicator of node.System cannot send alarm data by software to opposite end.
Summary of the invention
The present invention provides a kind of one-way optical fiber data alarm method, wherein can receive the method that the node of optical signal utilizes Unidirectional light chain road direction peer node to send alarm data.
The technical scheme is that
Detection fiber connection status, when optical fiber link exception, alerts by controlling the COM1 of optical fiber.
Further, when described optical fiber link exception, local fiber port is made to enter loop circuit state, until non-working port recovers normal；Send alarm data by local fiber port to opposite end simultaneously；Described detection fiber connection status is real-time.
Further, detecting the connection status of described optical fiber link in real time, when optical fiber link exception being detected, microprocessing unit is forced to arrange local fiber port by SMI (Serial management interface) interface and is entered loop circuit state.
A kind of one-way optical fiber data alarm method of the present invention comprises the following steps:
Step one: when device power is run, the connection status of microprocessing unit first detection fiber port, when finding that fiber port is in connection status or is in not-connected status, then the state of this port of cycle detection；
Step 2: if by detection of connectivity means, microprocessing unit detects that fiber port is connected conversion to when connecting fault by normal, then the depositor that fiber port is corresponding is set by SMI interface, force to be set to fiber port local loop state, and send alarm data to peer node by fiber port；Then local loop state the state of cycle detection fiber port of fiber port are released.
Wherein, in described step 2, detection of connectivity means are detected for being detected by SMI (Serial Management Interface) or connecting display lamp by interface, port.
The another way making fiber port enter loop circuit state in the present invention is, when described optical fiber link exception, to feed them into loop circuit state by TX, RX two of fiber port is carried out short circuit to differential lines, is specially and TX+ is connected to RX+, TX-is connected to RX-.
The present invention has the advantage that relative to prior art
1, the present invention is when fiber port connects abnormal, makes fiber port enter local loop state, does not turns off connection, and send alarm data to peer node by fiber port, alarm mode is simply effective, improves the deficiencies in the prior art, connects abnormality alarming for optical fiber and provides new way.
2, the method for the present invention is simple to operate, in time optical fiber can be connected abnormal situation and alert, and attendant can pinpoint the problems and carry out follow-up maintenance in time and process.
3, currently available technology depends on chip itself and has the function of disconnected fine force revert link, and major part chip is not possess this function；The present invention does not relies on concrete chip, can be applicable in all similar network structures.

Fig. 1 is the schematic flow sheet of the inventive method；
Fig. 2 is the control principle drawing of the inventive method；
Fig. 3 is the alarm packet sectional drawing that opposite end of the present invention captures.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of one-way optical fiber data alarm method of the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of one-way optical fiber data alarm method of the present invention, connection status by real-time detection fiber link, when detecting that optical fiber link occurs abnormal, microprocessing unit is forced to arrange local fiber port by SMI (Serial management interface) interface and is entered loop circuit state (Loopback), until non-working port recovers normal.Send alarm data by local fiber port to opposite end simultaneously.
Comprise the steps:
Step one, when device power is run, the connection status of microprocessing unit first detection fiber port, when find fiber port be in connection status or be in not-connected status time, then the state of cycle detection the two port；
If step 2 microprocessing unit is by detection of connectivity means (such as: by SMI (Serial Management Interface), interface or port connect the means such as display lamp) detect that fiber port is connected conversion to when connecting fault by normal, then the depositor that fiber port is corresponding is set by SMI interface, force to be set to fiber port local loop state (Loop back), and send alarm data to peer node by fiber port.Then local loop state the state of cycle detection fiber port of fiber port are released.
Wherein, can reach the effect of loop by the way of TX, RX two of fiber port is carried out short circuit to differential lines too, specially TX+ is connected to RX+, TX-and is connected to RX-.
As it is shown on figure 3, the packet that four OAM in figure capture is sent to opposite end under disconnected fine state.Experiment proves that either arranging loop by depositor still arranges loop by relay and can reach design effect, and response time can control at 0.1 second, can meet generality network failure Alerting requirements.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
