As a one-box product (OTN+OCS), the equipment integrates functions such as WDM transport, ROADM, 40G, electrical T-bit cross-connection, cross-connections of any granularity in the range of 100M to 40G, ASON, and rich management and protection.
Transmission Equipment with High Integration and Ultra Capacity
The equipment is of high integration, which enables flexible service configuration. A network built with the equipment is easy to design, to expand, and to maintain, and requires a smaller number of spare parts.
The equipment supports access of massive services and centralized cross-connections and management of the services. This avoids assembly of multiple subracks. The equipment is of high integration. For example, one PID chip is integrated with tens of photoelectric components to achieve 12 x 10G transmission.
When used as an 80/40-channel system, the OptiX OSN 8800 supports:
* Service access over one channel of 2.5 Gbit/s, 10 Gbit/s, 40 Gbit/s.
* Transmission of 10 Gbit/s services over a distance of 5000 km, 40 Gbit/s services over a distance of 2000 km without electrical regeneration.
* Ultra long-haul transmission of 10 Gbit/s services over a 1 x 82 dB single span.
The OptiX OSN 8800 CWDM systems support service access over eight wavelengths. Each wavelength supports a maximum rate of 2.5 Gbit/s.
The ASIC and PID technologies enable design of a board with high density and help reduce power consumption of each port. Ultra cross-connections help reduce bridging at many ODF and also save space in telecommunications rooms.
The OptiX OSN 8800 T16 supports centralized cross-connections through a cross-connect board. The OptiX OSN 8800 T16 provides one type of cross-connection boards, that is, XCH. It supports hybrid cross-connections of ODU0, ODU1, ODU2, ODU3, and ODUflex signals, and supports a 640 Gbit/s cross-connect capacity to the maximum.
The OptiX OSN 8800 T32 supports centralized cross-connections through a cross-connect board. The OptiX OSN 8800 T32 provides one type of cross-connection boards, that is, XCH. It supports hybrid cross-connections of ODU0, ODU1, ODU2, ODU3, and ODUflex signals, and supports a 1.28 Tbit/s cross-connect capacity to the maximum.
The OptiX OSN 8800 T64 provides three types of cross-connect boards, that is, XCT, SXH and SXM. The XCT must be used together with SXH or SXM. The OptiX OSN 8800 T64 supports hybrid cross-connections of ODU0, ODU1, ODU2, ODU3, and ODUflex signals, and supports a 2.56 Tbit/s cross-connect capacity to the maximum.
Dynamic Optical-Layer Cross-Connections
Dynamic intra-ring grooming and inter-ring grooming can be realized using the ROADM board.
Dynamic optical layer grooming can be classified into intra-ring grooming and inter-ring grooming, or into two-dimensional grooming and multi-dimensional grooming.
Dimension refers to transmission direction. Two-dimensional grooming refers to wavelength grooming in two transmission directions. Multi-dimensional grooming refers to wavelength grooming in multiple transmission directions.
Flexible Electrical-Layer Cross-Connections
The equipment supports non-blocking electrical cross-connections, centralized cross-connections of massive services, and complex networking.
Full Service Access over Shared 10G and 40G Channels
The ODUk sub-wavelengths can be flexibly combined to share 10G/40G line bandwidth for transmission. This enables uniform carrying of any services over one wavelength and therefore improves wavelength utilization to a great extent.
Bandwidth is tailored for services. This improves the efficiency of transmission bandwidth and achieves “zero waste” of bandwidth.
Hybrid O/E Cross-Connections and Quick Service Deployment
Hybrid O/E cross-connections achieve flexible cross-connections of wavelength or sub-wavelength services. Quick service deployment helps reduce CapEx. On a flattened network, services are easy to plan, deploy, and expand. Much less time needs to be taken to provision a service.
The tributary/line separated structure maximizes the return on investment and reduces the number of spare parts. When service type changes, users only need to replace the tributary boards but fully reuse the existing line boards. The use of independent line and tributary boards reduces the number and type of spare parts from N x M to N + M (N, M > 2), thereby helping operators reduce construction costs.
Rich OAM, Easy Maintenance, and Lower OpEx
The rich O/E overhead information on OTN equipment leads to a more transparent network, facilitates fault identification, and helps reduce maintenance costs.
The PRBS function enables quick self-check of OTUs, quick assessment of channel performance, and quick fault identification.
The “5A” auto-adjustment function:
* Automatic level control (ALC) function effectively resolves the problem of attenuation of fibers operating over a long term.
* Automatic gain control (AGC) enables adaptation to transient changes in the number of wavelengths.
* Automatic power equilibrium (APE) enables auto-optimization of OSNR specification of each channel.
* Intelligent power adjustment (IPA) avoids personal injuries (to eyes or bodies) resulting from laser radiation in case of anomalies such as a fiber cut.
* The optical power adjust (OPA) is made to ensure that the input power of the OTU board and OA board meet the commissioning requirements.
Support monitor channel power, central wavelength, OSNR, and overall optical spectrum, and also supports remote real-time measurement of optical spectrum parameters.
