Description
Technical field
The present invention relates to optical communication technique field, relate in particular to a kind of simplex optical module, communication equipment and connection error detection method.
Background technology
In prior art, optical communication, compared with the communication such as cable, microwave, has multiple advantage, for example: optical communications frequencies as outline is high, bandwidth, and message capacity is large, and security performance is good, and loss is little, repeater span is long, and antijamming capability is strong etc.Exactly because these advantages of optical communication, optical communication network becomes the basic platform of modern communication networks.Along with the development of optical communication technique, optical module has also had application more and more widely.Optical communication can be implemented as: optical module is installed in communication equipment, send to the signal of telecommunication of Correspondent Node to be converted to light signal communication equipment by optical module, and transmit by optical fiber, and send to the light signal of communication equipment to be converted to the signal of telecommunication Correspondent Node, then electric signal transmission is processed to communication equipment.
Optical module has different packing forms, common packing forms can comprise: compact package form (SFF, Small Form Factor), plug-in compact package form (SFP, Small Form-factor Pluggable), (SFP+, SFP PLUS), (XFP, 10Gigabit Small Form Factor Pluggable) etc., wherein, SFF, SFP have hundred, gigabit speed, and XFP, SFP+ have 10,000,000,000 speed.And these optical modules, all use two fine transmitted in both directions technology, use two Optical Fiber Transmission, one for sending, and one for receiving.Therefore there is the problem of waste fiber resource in duplex optical module.
With respect to duplex optical module, single fiber bi-directional (BIDI) optical module only uses an optical fiber to realize and sends the transmitted in both directions receiving, and has saved fiber resource.Owing to having reduced networking and operation cost, simplex optical module is widely used in the fields such as FTTx, OTN, wireless backhaul, dedicated transmissions net, video monitoring, is also applicable to fiber resource lay, and needs in the Access Network or local area network (LAN) of dilatation.
Why simplex optical module can realize bi-directional full-duplex transmission in an optical fiber, because the light signal of sending and receiving uses different wavelength, as combinations such as 1310/1550nm, 1310/1490nm, 1470/1610nm, two different wavelength signals are set up two channels and can phase mutual interference in same optical fiber.Fig. 1 is simplex optical module operation principle schematic diagram, as shown in Figure 1, simplex optical module is mainly by optical wavelength-division multiplex (WDM, Wavelength Division Multiplexing) light splitting piece 101 realizes the processing to two different wave length light signals, the wavelength X that WDM light splitting piece 101 sends transmitting terminal
1light signal 102, be transmissive state, make the transmission light signal 102 of wavelength 1 be coupled to Transmission Fibers; The wavelength X that receiving terminal is received
2light signal 103, be total reflection state, make wavelength X
2receiving optical signals reflex to receiving terminal, so just formed point light action for the transmitting of different wave length and reception.
But, simplex optical module is subject to it to realize principle to limit, must use in pairs, that is to say, if communicating pair one end has been used 1310nm TX/1550nm RX (to send wavelength of optical signal 1310nm, receiving optical signals wavelength 1550nm) optical module, the other end of communicating pair just must use 1550nm TX/1310nm RX (sending wavelength of optical signal 1550nm, receiving optical signals wavelength 1310nm).If two ends have all been used same size optical module, suppose that two ends are all used the optical module of 1310nm TX/1550nm RX, due to the effect of WDM light splitting piece 101, the light signal transmission that WDM light splitting piece 101 can be 1310nm by wavelength, and the light signal that is 1550nm by wavelength reflection, the wavelength of optical signal sending due to two ends is 1310nm, the light signal transmission that the wavelength that WDM light splitting piece 101 can send Correspondent Node is so 1310nm, and can not reflect, the receiving terminal of communication ends cannot receive the light signal of reflection so, just cannot connect with Correspondent Node.
In prior art, simplex optical module just clearly identifies model on label, wavelength etc., when installation, rely on and manually match according to label model, and dependence hand inspection pairing model, may there is misjudgment, think wrong pairing by mistake correct pairing, and, because the optical module of intercommunication is mutually generally distant, from hundreds of rice to tens kms, kms even up to a hundred, when communicating pair connects when unsuccessful, the other end beyond need to be to hundreds of rice to kms up to a hundred goes to confirm whether communicating pair connects unsuccessful reason is that communicating pair simplex optical module does not mate, the positioning problems time is long, efficiency is low.
