3.Core functional characteristics

Functional Module Technical Description System Value

The dual optocouplers are combined into two independent 1x2 or 2x2 optocouplers, which can simultaneously couple and allocate power to two optical signals, save subrack slots, simplify optical layer design, and are suitable for scenarios that require multi-channel coupling

Multiple split ratio options are available, supporting various split ratio configurations such as 50:50, 90:10, 95:5, etc.The 90:10/95:5 port can be flexibly selected for optical performance monitoring according to monitoring or protection needs, while the 50:50 port can be used for protection switching or load sharing

1+1 protection coupling is used in OTM sites to achieve 1+1 protection coupling between primary and backup optical channels, ensuring that services can quickly switch to backup channels in case of primary channel failure, improving network survivability, and ensuring high service availability

Low insertion loss optimized optical design minimizes power loss of signals through couplers, reduces pressure on the system's optical power budget, and extends transmission distance

High isolation between ports provides excellent isolation characteristics to prevent channel crosstalk and ensure signal quality

Passive design is entirely based on passive optical components to achieve functionality, without the need for power supply, zero power consumption, and zero heat generation.It has extremely high reliability and long service life, without the need for heat dissipation considerations

Hot swappable design supports online hot swappable replacement to reduce business interruption time and improve maintenance convenience

7.Application scenarios

Core Value of Application Scenario Deployment Method

1+1 optical channel protection is used at the sending end of the OTM station, where the main and backup optical signals are combined through a 50:50 coupler and sent into the line;Fast protection switching of the optical layer is achieved by splitting the light to the primary and backup receivers through couplers at the receiving end, improving network reliability

The optical performance monitoring point utilizes the monitoring port of a 90:10 or 95:5 coupler, connected to an OPM unit or spectral analyzer, to monitor the optical channel performance in real-time without affecting the main business

Primary and backup signal allocation is used in scenarios where one optical signal needs to be sent simultaneously to two different directions, using a 50:50 coupler to achieve signal broadcasting or load sharing

Optical power balance is used in scenarios where optical power needs to be adjusted, and power allocation is flexibly adapted to different power budget requirements through couplers with different splitting ratios

Laboratory testing is conducted in a testing environment to separate light and facilitate the connection of multiple testing instruments simultaneously

8.Maintenance and ordering information

Project Information

Component code TN11DCP

Ordering instructions: When placing an order, it is necessary to specify the splitting ratio (50:50/90:10/95:5) and port configuration

On site operation supports hot plugging, and anti-static wrist straps should be worn during operation.Pay attention to cleaning the fiber optic connectors

Test and verify that insertion loss testing and port connectivity testing are required after installation

Spare parts management, as a passive component, has high reliability and can appropriately reduce the proportion of spare parts, but key nodes can be configured with spare parts
