Description
The 155M 1X9 Optical Transceiver Module (SSF) offers high-performance, dual-wavelength data transmission over extended distances. Featuring advanced FP and DFB laser technologies, these modules support bidirectional communication using separate transmit/receive wavelengths (e.g., T1310/R1550nm), ensuring efficient signal separation and minimal interference. Designed with industry-standard 1X9 form factor, dual power supply compatibility (3.3V/5V), and SC connector interface, they provide reliable connectivity for diverse applications across varying distances (2KM to 120KM)
Applications
- Bidirectional Fiber Links: Ideal for point-to-point communication requiring simultaneous data exchange.
- Metropolitan Area Networks (MANs): Enables efficient connectivity between network nodes in urban areas.
- Fiber-to-the-Home (FTTH): Supports high-speed residential and business broadband access.
- Enterprise Networks: Connects geographically dispersed offices and data centers.
- Telecommunication Infrastructure: Backbone and access network deployments requiring bidirectional transmission.
