Description
Technical field
The present invention relates to technical field of photo communication, particularly relate to a kind of simplex optical module, communication equipment and
Connection error detection method.
Background technology
In prior art, optic communication, compared with the communication such as cable, microwave, has multiple advantage, such as: light
Communication frequency is high, bandwidth, and message capacity is big, and security performance is good, be lost little, repeater span is long, anti-dry
Ability of disturbing is strong.Exactly because these advantages of optic communication, optical communication network becomes the basis of modern communication networks
Platform.Along with the development of optical communication technique, optical module there has also been and is increasingly widely applied.Optic communication is permissible
It is embodied as: optical module is installed in a communications device, by optical module, communication equipment is sent to Correspondent Node
The signal of telecommunication is converted to optical signal, and is transmitted by optical fiber, and Correspondent Node is sent to communication equipment
Optical signal be converted to the signal of telecommunication, then the signal of telecommunication be transferred to communication equipment process.
Optical module has different packing forms, and common packing forms may include that 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
Rate.And the double fine transmitted in both directions technology of these optical modules, all use, i.e. two fiber-optic transfer of use, one
For sending, one is used for receiving.Therefore, the problem that duplex optical module exists waste fiber resource.
Relative to duplex optical module, single fiber bi-directional (BIDI) optical module only uses an optical fiber to realize sending out
Send the transmitted in both directions of reception, save fiber resource.Owing to reducing networking and operation cost, single fiber
Bidirectional optical module is widely used in the necks such as FTTx, OTN, wireless backhaul, dedicated transmissions net, video monitoring
Territory, is also applied for fiber resource and lays, and needs in access network or the LAN of dilatation.
Why simplex optical module can realize bi-directional full-duplex transmission in an optical fiber, is because sending
Different wavelength is used, such as 1310/1550nm, 1310/1490nm, 1470/1610nm with the optical signal received
Deng combination, two different wavelength signals set up two channels and will not be the most dry in same optical fiber
Disturb.Fig. 1 is simplex optical module operation principle schematic diagram, as it is shown in figure 1, simplex optical module master
OWDM to be passed through (WDM, Wavelength Division Multiplexing) light splitting piece 101 is real
The now process to two different wave length optical signals, the wavelength X that transmitting terminal is sent by WDM light splitting piece 1011
Optical signal 102, be transmissive state, make the transmission optical signal 102 of wavelength 1 be coupled to Transmission Fibers；Right
The wavelength X that receiving terminal receives2Optical signal 103, be total reflection state, make wavelength X2Reception optical signal
Reflex to receiving terminal, material is thus formed launching and the light splitting effect received for different wave length.
But, simplex optical module is realized principle by it and is limited, it is necessary to use in pairs, say, that as
Really communicating pair one end employ 1310nm TX/1550nm RX (send wavelength of optical signal 1310nm, connect
Receive wavelength of optical signal 1550nm) optical module, the other end of communicating pair be necessary for use 1550nm
TX/1310nm RX (sends wavelength of optical signal 1550nm, receive wavelength of optical signal 1310nm).If two
End all employ same size optical module, it is assumed that two ends all use the optical mode of 1310nm TX/1550nm RX
Block, due to the effect of WDM light splitting piece 101, wavelength can be 1310nm's by WDM light splitting piece 101
Optical signal transmission, and by the optical signal reflection that wavelength is 1550nm, the wavelength of optical signal sent due to two ends
It is 1310nm, then the wavelength that Correspondent Node can be sent by WDM light splitting piece 101 is 1310nm's
Optical signal transmission, without reflecting, then the receiving terminal of communication ends cannot receive the optical signal of reflection, just
Cannot set up with Correspondent Node and be connected.
In prior art, simplex optical module simply clearly identifies model, wavelength etc. on label, peace
Rely on during dress and manually match according to label model, and rely on hand inspection pairing model, in fact it could happen that misdeem
By mistake, the pairing of mistake is mistakenly considered correct pairing, and, the general distance of optical module owing to being in communication with each other
Farther out, from hundreds of rice to tens kms, even hundred kilometers, when communicating pair connects unsuccessful, need
The other end beyond to hundreds of rice to hundred kilometers goes to confirm that communicating pair connects unsuccessful reason and is whether
Communicating pair simplex optical module does not mates, and the positioning problems time is long, and efficiency is low.
