Fiber optic backbone network: TSS-GEL2-55DIR transceiver is suitable for building fiber optic backbone networks for long-distance data transmission and connecting different network nodes. It can support high-speed data transmission and stable signal transmission, allowing network operators to provide reliable broadband services.

Metropolitan area network expansion: When expanding networks within a city, the TSS-GEL2-55DIR transceiver can be used to connect different local area networks (LANs) or data centers and transmit data over single-mode fiber. It makes network connections across longer distances feasible, providing greater coverage.

Data center interconnection: In large-scale data centers, the TSS-GEL2-55DIR transceiver can be used to interconnect fiber optic links between different data centers. It supports long-distance transmission and can meet the needs of data backup, disaster recovery and data sharing, ensuring efficient and reliable data transmission.

Remote monitoring: For applications that require the transmission of video and surveillance data over long distances, such as security monitoring systems or video conferencing systems, the TSS-GEL2-55DIR transceiver provides a stable optical fiber transmission solution. It can connect surveillance cameras and monitoring equipment, transmit video and data to the remote monitoring center, and achieve real-time monitoring and remote management.

Military communications: The TSS-GEL2-55DIR transceiver also has potential in military communications applications due to its durability and wide operating temperature range. It can be used in military communication networks, field command systems, military radars, etc. to provide reliable data transmission and network connections.



Connector Type: The TSS-GEL2-55DIR transceiver typically comes with a standard LC connector. However, if you have specific requirements for a different connector type, such as SC or ST, you can discuss with the manufacturer if they offer customization options to provide the desired connector type.

DDM/DOM Support: Digital Diagnostic Monitoring (DDM) or Digital Optical Monitoring (DOM) is a feature that allows monitoring the performance and health of the transceiver, including parameters like temperature, voltage, and optical power levels. If this feature is essential for your application, you can inquire about the availability of DDM/DOM support for the TSS-GEL2-55DIR transceiver.

Labeling and Branding: Depending on your requirements, it may be possible to have custom labeling or branding on the transceiver module. This can be useful for identification and branding purposes within your network infrastructure.

Extended Temperature Range: The TSS-GEL2-55DIR already has a wide operating temperature range of -40℃ to +85℃. However, if you have specific temperature requirements beyond this range, you can discuss with the manufacturer if they offer customization options for even higher or lower temperature ranges.

Additional Features: You can also inquire about the possibility of adding additional features or functionalities to the transceiver based on your specific requirements. This could include features like power monitoring, diagnostic capabilities, or enhanced security measures.
