The OptiX OSN 810 is a
WDM-based full-outdoor active transport device. It can be used for
service transmission on metro C-RAN networks and supports hybrid
transmission of CPRI 2–CPRI 8, GE/10GE LAN, OBSAI, and SDH services.
OptiX OSN 810 supports pole-mounted installation, wall-mounted
installation, and installation with wireless RRUs. It features a
compact and lightweight structure, allowing one person to install
the equipment on a tower. In addition, OptiX OSN 810 is both
commissioning-free and configuration-free, and is an optimal
fronthaul bearer solution in the LTE/LTE-A era.
TThe OptiX OSN 810 applies to
metro edge nodes, and supports point-to-point networking and chain
networking.
The OptiX OSN 810 is used to implement the C-RAN bearer solution.
Figure below shows the application of the OptiX OSN 810 in the WDM
system
| OSN 810 Type | C12X5 Board Type |
| 050N1T12DSA | N1SA |
| 050N2T12DSA | N1SA NOTE The C12X5 board must be used together with the OLP board. |
| 050N1T12DDEA | N1DEA |
| 050N1T12DDEB | N1DEB |
| 050N1T12DDEC | N1DEC |
In autonegotiation mode, the service rate at the BBU port of the C12X5 board is fixed, and the C12X5 board can automatically adapt to the received CPRI services. The OptiX OSN 810 can also automatically adapt to the received CPRI services. Therefore, you do not need to manually configure the types of received services. Figure below shows the procedure of service autonegotiation.
The prerequisites for using the service autonegotiation function are
as follows:
The BBU port rate of the C12X5 board is fixed.
The total bandwidth of the received services is equal to or less than 50 Gbit/s.
In the point-to-point networking mode, the OptiX OSN 810 supports optical line 1+1 protection and a transmission distance reaching 10 km, applicable to scenarios where BBUs are loosely or intermediately centralized. If the optical line 1+1 protection mode is not used, the OptiX OSN 810 supports a transmission distance reaching 17 km, applicable to scenarios where BBUs are massively centralized.
In the chain networking mode, the OptiX OSN 810 does not support
optical line 1+1 protection. In a two-fiber bidirectional networking
scenario, one OptiX OSN 810 can be cascaded with at most two OptiX
OSN 810s. The transmission distance between the last OptiX OSN 810
and BBUs reaches 17 km. Therefore, chain networking is applicable to
scenarios where BBUs are massively centralized.
Note: In cascading scenarios, the C12X5 board (on the OptiX OSN 1800 equipment) connected to the OptiX OSN 810 must be equivalently cascaded. To be specific, one OptiX OSN 810 connects to one C12X5 board. They can implement service autonegotiation after being connected.
