3.Core functional characteristics

Functional Module Technical Description System Value

1: 1 OTS optical line protection provides 1:1 line protection for the optical transmission section, which must be paired with TN11OLSPA and deployed upstream and downstream of the fiber.In the event of a main fiber failure, it switches to the backup fiber in milliseconds to ensure uninterrupted service

The protection mechanism adopts a selective sending and receiving and dual end switching mechanism to ensure reliable switching between the working path and the protection path, achieving fast and reliable protection switching and ensuring business continuity

IEEE 1588v2 supports transparent transmission of high-precision time synchronization protocols, without the need for additional testing and delay compensation, providing critical support for time sensitive services such as 5G mobile backhaul and simplifying synchronous network deployment

The auxiliary light source configuration protection channel can provide C-band auxiliary light signals through SFP module (auxiliary light source 1) or OA board (auxiliary light source 2) to monitor the status of the protection channel and flexibly adapt to different device configurations, ensuring that the protection channel can always be monitored

Fiber optic quality monitoring supports fiber optic quality monitoring of working channels and protection channels.Monitoring signals are input/output through RFM interfaces to assist in determining the health status of fiber optic links, warning potential faults in advance, and achieving preventive maintenance

The built-in optical power detection module monitors the input/output optical power of the working channel and protection channel in real-time, providing a basis for protection switching decisions and assisting in fault diagnosis

2x2 optical switches enable switching between the working channel and the protection channel, with a response time that meets protection requirements to ensure fast and reliable protection switching

When used in conjunction with the SFIU board at the optical regeneration station, it can be networked with the SFIU board to expand network coverage and support longer distance transmission

OSC must be used in conjunction with TN12ST2 or TN13ST2 boards to ensure correct transmission of OSC signals

Does the optical layer ASON support -

4.Optics and working parameters

Parameter specification remarks

Fiber type single-mode is suitable for conventional optical power scenarios

The working wavelength C-band auxiliary light source also uses the C-band

The protection mechanism selects sending and receiving, and the dual end switching protection channel uses an auxiliary light source to monitor the status

The auxiliary light source wavelength in the C-band can be provided by SFP modules or OA boards

The business signal in normal working mode is transmitted through the working channel, and the SFP module sends C-band auxiliary light to the protection channel to monitor the status of the protection channel

When the working channel of the fault switching mode fails, both the transmitting and receiving ends switch simultaneously, the service switches to the protection channel, and the auxiliary light switches to the working channel to monitor its status

Raman board compatibility does not support configuring Raman boards between network elements interconnected through OLSPA/OLSPB boards

5.Requirements for compatible board cards

Explanation of requirements for board version coordination

OLSP must be used in pairs with TN11OLSPA, and TN11OLSPB must be deployed in pairs with TN11OLSPA upstream and downstream of the fiber optic cable

The ST2 board TN12ST2 or TN13ST2 is used for OSC signal processing, and the working and protection circuits of each regeneration station must be configured and located in the same sub rack as OLSPA/OLSPB

The system control board needs to be configured to be located on the same shelf as the OLSPB board and ST2 board

The STG board needs to be configured to be located on the same shelf as the OLSPB board and ST2 board

SFIU board TN11SFIU can be used in conjunction with optical regeneration stations

OA board (if used as an auxiliary light source) - needs to operate in power lock mode, and the input port must be suspended (unable to receive light)

6.Comparison with TN11OLSPA

Features TN11OLSPA TN11OLSPB

Component code 03052FAC 03052FAE

Pairing relationship must be paired with OLSPB and OLSPA

The interface differences include TI1/TO1, TI2/TO2, and RI1/RI2.The interfaces include TO1/TO2, RI1/RI2, and RO1/RO2

Signal flow direction is biased towards the sending side for processing and towards the receiving side for processing

Initial software version V100R002C10SPC300 V100R002C10SPC300

7.Application scenarios

Core Value of Application Scenario Deployment Method

1:1 protection for trunk fiber optic cables: A pair of OLSPA/OLSPB boards are deployed at each end of the trunk line to connect the working fiber optic cable and the protective fiber optic cable.When the working fiber optic cable is interrupted, it automatically switches to the protective fiber optic cable to ensure uninterrupted backbone services

Optical regeneration site protection is implemented in long-distance links with regeneration sites.OLSPA/OLSPB is configured at both ends of the regeneration site, and combined with SFIU board networking to achieve cross regeneration section optical line protection and expand the protection range

Deploying IEEE 1588v2 transparent transmission capability in line protection nodes that require high-precision time synchronization in 5G bearer network time synchronization scenarios simplifies synchronous network deployment without the need for additional debugging and delay compensation

High value customer dedicated line protection provides 1:1 protection at the fiber optic cable level in important customer dedicated lines at the access layer, meeting the strict requirements of high-value customers such as finance, government, and enterprises for network reliability

8.Maintenance and ordering information

Project Information

Component code TN11OLSPB (03052FAE)

The ordering instructions must be paired with TN11OLSPA to specify whether it needs to be configured with SFIU board and auxiliary light source (SFP module or OA board)

On site operation supports hot plugging, and attention should be paid to cleaning the fiber optic connectors during operation to ensure correct pairing of A/B boards

After testing and verifying installation, protection switching function testing, optical power monitoring calibration, and 1588v2 transmission testing (if used) are required

Spare parts management, as a paired protection board, is recommended to configure paired spare parts at critical nodes

Software dependency requires support from the host software version (V100R002C10SPC300 and above)

Attention • Cannot coexist with Raman board between network elements interconnected through OLSPA/OLSPB

If using an OA board as an auxiliary light source, the OA input port must be suspended

Core Summary:

TN11OLSPB is a B-type board specifically designed for 1:1 optical transmission section (OTS) line protection on the OSN 9800 platform, and must be used in pairs with TN11OLSPA. It adopts a selective sending and receiving and dual end switching mechanism, which switches to the backup fiber in milliseconds when the main fiber fails, ensuring uninterrupted business. The board supports IEEE 1588v2 transparent transmission without the need for additional testing and delay compensation, making it particularly suitable for high-precision time synchronization scenarios such as 5G bearer. Real time monitoring of protection channel status through auxiliary light sources (SFP modules or OA boards), and supporting fiber quality monitoring function. Combined with SFIU board and TN12ST2/TN13ST2 board, cross section protection can be achieved at the optical regeneration station.

Core values and positioning:

Paired use, 1:1 line protection: must be paired with TN11OLSPA to provide reliable OTS optical line protection.

1588v2 transparent transmission capability: No need for debugging and delay compensation, simplifying synchronous network deployment.

Auxiliary light source monitoring: Provide C-band auxiliary light through SFP modules or OA boards to monitor the status of protection channels in real time.

Application suggestion:

This board is suitable for trunk optical cables, optical regeneration stations, and high-value customer dedicated line scenarios that require 1:1 optical line protection. When deploying, it is necessary to follow the principle of pairing with TN11OLSPA, ensure compatibility with versions of ST2 board and SFIU board, and note that Raman board cannot coexist with them.
