Description du produit

1.Product Overview

TN56NS3 is a 1-port 40G OTN line service processing board designed for OptiX OSN9800, OSN8800, and OSN6800 series wavelength division devices.It adopts high-order coherent reception and enhanced error correction technology, and works in both electric relay REG mode and line terminal TM mode.It completes single 40G signal 3R regeneration, OTN encapsulation and decapsulation, multi granularity service aggregation, layer crossing, and wavelength conversion, and is suitable for dual slot deployment in U32 and U64 subracks.It is a high-end core service board for backbone ultra long distance, metropolitan core, and data center interconnection 40G coherent wavelength division networks.

1.Basic specifications and physical characteristics

TN56NS3 adopts a standard 1U dual slot board structure, with physical dimensions of 261.5mm, 202.6mm, and 22.0mm, and a weight not exceeding 1.1kg, suitable for high-density deployment in computer rooms.The power supply adopts 48V DC, with a voltage range of 38.4V to 57.6V, a typical power consumption of 100W, and a maximum power consumption of 115W when fully equipped with single 40G business.The standard operating temperature range is 0? to 45?, the extended range is 5? to 55?, the storage temperature is 40? to 70?, the relative humidity is 5% to 95% without condensation, and the MTBF is not less than 120000 hours.It has passed CE, FCC, and RoHS certifications, meeting the high reliability and environmental protection requirements of telecommunications grade.

2.Core functions and business processing capabilities

The business speed supports two 40G OTN standards, OTU3 43.02Gbit/s and OTU3e 44.58Gbit/s, compatible with customer side business access such as 40GE, STM-256, OC-768, FC3200, SDH VC-4, and supports mixed transmission of OTN and SDH services. The business mapping capability supports the aggregation of 32 ODU0, 32 ODUflex, 16 ODU1, 4 ODU2, 4 ODU2e, and 1 ODU3 into 1 OTU3, 4 ODU2e into 1 OTU3e, and 256 VC-4 into 1 OTU3. In the OSN8800 T64 subrack, it supports a maximum of 128 VC-4 services, achieving efficient aggregation of multi granularity low-speed services and high-speed wavelength scheduling. The error correction mode supports standard FEC, enhanced AFEC-2, and high-order coherent HFEC. HFEC can significantly improve OSNR tolerance, extending the maximum transmission distance of standard single-mode fiber to over 250km and adapting to ultra long distance coherent transmission scenarios. The complete cost processing supports OTN SM, PM, and TCM costs, supports ESC embedded control channels and PRBS testing, provides BIP8 byte monitoring, laser bias current/temperature/optical power monitoring, and ensures network management and fault location requirements. Loop back testing supports line side, customer side, ODU0, ODU1, ODU2, ODU3, and VC-4 channel loop back, facilitating business debugging and troubleshooting. Protection mechanism includes 1+1 protection inside the cover plate ODUk SNCP, Branch SNCP and SDH SNCP/MSP ring network protection, with service switching time not exceeding 50ms, meet the high reliability requirements of critical services.

3.Optical interface parameters

One 40G coherent optical port is equipped on the line side, using LC duplex connectors and modulation method DQPSK coherent modulation.The optical module supports the C-band 50GHz interval adjustable wavelength type, with a working wavelength coverage of 1528.77nm to 1563.86nm.It supports Super C-band extension and is suitable for high-density DWDM 80 wave networking.The typical range of transmitting optical power is 0dBm to 3dBm, and the receiving sensitivity is better than 24dBm under BER ≤ 10E-12 conditions.The dispersion tolerance is not less than 4000ps/nm, suitable for ultra long distance single-mode fiber coherent transmission scenarios.

4.Version compatibility and deployment requirements

The TN56NS3 basic model is compatible with OSN9800/8800/6800 system V100R00C00 version, and is equipped with TN52UXCM, TN52XCH, TN16UXCM main control boards.It supports basic OTU3 processing, FEC error correction, and TM mode.Supporting REG electric relay mode, AFEC-2 and HFEC enhanced error correction requires V100R011C00 and above system versions.In terms of deployment requirements, the OSN8800 T64 regular subrack needs to be paired with XCT+SXH or XCT+XM cross boards, while the enhancer subrack can be paired with XCT+SXH, XCT+XM, or UXCT+USXH;To receive SDH services on OSN8800 T16 subrack, TN16UXCM main control board is required.SDH services only support independent subrack deployment, while OTN services support independent, master, and slave subrack deployment.

5.Typical application scenarios

TN56NS3 is mainly used in three major scenarios: first, ultra long distance backbone DWDM electrical relay REG sites, achieving 3R regeneration of single 40G coherent signals, significantly reducing the number of relay sites, and improving network coverage and bandwidth density; The second is the interconnection between the urban core and the data center, which completes the conversion of 40GE/STM-256/FC3200 and other services to DWDM wavelengths, and supports the scheduling of mixed OTN and SDH services; The third is high-density flexible networking, combined with adjustable wavelength modules and ODUk SNCP protection, to achieve dynamic channel resource adjustment in mesh networks, improve network utilization and business reliability.
