7、 Multichannel seeded DWDM applications with single-channel optical interfaces Summary Recommendation ITU-T G.698.3 provides optical parameter values for physical layer interfaces of seeded dense wavelength division multiplexing (DWDM) systems primarily intended for metro applications. Applications a
8、re defined using optical interface parameters and values for single-channel and multichannel interfaces of seeded DWDM multichannel optical systems in point-to-point applications. This Recommendation uses a system architecture comprising a head-end, connecting to the tail-end equipment (TEE) through
9、 a black link. The head-end houses a set of transmitters and receivers and an optical multiplexer and demultiplexer (OD/OM) in addition to a seed signal source. A single bidirectional fibre is used to connect the head-end to the passive OD/OM. Connection between OD/OM and remote TEE is also bidirect
10、ional. At the tail-end, all transmitters use a seed signal to lock to the desired transmission wavelength. The initial version of this Recommendation includes seeded DWDM application at 1.25 Gbit/s with 100-GHz channel frequency spacing. History Edition Recommendation Approval Study Group 1.0 ITU-T
11、G.698.3 2012-02-13 15 ii Rec. ITU-T G.698.3 (02/2012) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a
12、 permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, es
13、tablishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary
14、standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the
15、 Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equival
16、ents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a clai
17、med Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had r
18、eceived notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.itu.int/ITU-T

22、ITU-T G.698.3 (02/2012) 1 Recommendation ITU-T G.698.3 Multichannel seeded DWDM applications with single-channel optical interfaces 1 Scope The purpose of this Recommendation is to provide optical interface specifications towards the realization of transversely compatible seeded dense wavelength div
23、ision multiplexing (DWDM) systems primarily intended for metro applications. This Recommendation defines and provides values for optical interface parameters of point-to-point seeded DWDM applications (with maximum transmission distance of about 40 km) on single-mode optical fibres through the use o
24、f the “black link“ approach. Applications containing amplifiers within the black link are outside the scope of this Recommendation. This Recommendation describes seeded DWDM systems that include the following features: Channel frequency spacing: 100 GHz; Bit rate of signal channel: up to 1.25 Gbit/s
