TP-Link ISM321A-20, Omada
TP-Link ISM321A-20, Omada
The TP-Link ISM321A-20 Omada SFP module extends the transmission distance in optical networks up to 20km. This optical transceiver operates on a single-mode optical fibre with a diameter of 9/125µm and transmits data. The design uses WDM technology for bidirectional transmission over a single fibre to reduce overall cabling costs. The device operates at a transmission speed of 1.25Gb/s and supports the SFP-MSA standard for compatibility with other network elements. Connection is made using a single LC Simplex connector, and the module complies with the IEEE 802.3z and TCP/IP standards.
Key Features of the TP-Link ISM321A-20 Omada Module
- WDM technology for bidirectional transmission over a single optical fibre
- Industrial operating temperature range from -40 to 85°C
- DDM function for real-time link status monitoring
- Hot-swappable for plug-and-play installation and removal
- Transmission distance of up to 20km
- Compatibility with the SFP-MSA standard
Bidirectional Transmission and Industrial Use of the TP-Link ISM321A-20 Module
WDM technology integrates both signal transmission and reception into a single optical fibre. The module transmits at a wavelength of 1,550nm and receives a signal at a wavelength of 1,310nm. This transmission method eliminates the need for a separate cable for the return path. The single-fibre solution saves on installation and maintenance costs for the optical path. The device requires a counterpart with opposite wavelengths for the link to function correctly. The design meets the requirements for operation in unstable temperature conditions. The components can withstand temperature fluctuations ranging from -40°C to 85°C. The module is suitable for use in industrial cabinets and outdoor installations. The casing protects the internal electronics from external interference and mechanical damage. Functionality within this temperature range prevents unexpected network outages.
Management, Diagnostics, and Compatibility
The SFP-MSA standard defines the precise dimensions and electrical interface for integration. The module fits into standard SFP slots of various network elements. Hot-swappable support allows for installation or replacement during operation without needing to restart the entire switch. Hot-swapping reduces maintenance time to a minimum. It is powered directly from the slot with a voltage of 3.3V. The integrated DDM function provides real-time information about the status of the optical link. The network administrator can monitor the temperature, supply voltage, and the power of the transmitter and receiver. This information helps prevent failures in the transmission path. Digital diagnostics simplify troubleshooting in the optical network without special measuring instruments. The 1.25Gbps transmission speed is suitable for standard gigabit applications.
