Applications:
The TSB-GE20-53DIR transceiver is suitable for optical communication networks where a data rate of 1.25 Gbps is sufficient.
The BIDI (Bi-directional) feature allows for bidirectional communication over a single fiber, using different wavelengths for transmitting and receiving signals. This makes it suitable for applications where only one fiber is available or for cost-effective deployments.
The transmission distance of 20 kilometers makes it suitable for medium-reach optical communication networks, such as local area networks (LANs), metropolitan networks, or campus networks.
The specific wavelength combination of 1550nm and 1310nm suggests that this transceiver is likely designed for use in GPON (Gigabit Passive Optical Network) or EPON (Ethernet Passive Optical Network) applications. These are popular fiber-optic access technologies used for broadband services in residential and business environments.
The wide temperature range of -40℃ to +85℃ makes this transceiver suitable for deployment in harsh environmental conditions, such as outdoor or industrial environments.
