Transmitters & Receivers
The ROSA (Receiver Optical Sub-Assembly) is built on a proven transceiver fabrication platform, offering industry-leading attributes in low cost, high bandwidth, high coupling efficiency, and long-term stability. As a key component in optical networks, it converts optical signals into electrical signals. This specific ROSA variant is designed without a transimpedance amplifier (TIA), enabling high-fidelity analog signal output and making it especially well-suited for precision analog applications. The sensitivity of the ROSA is approximately proportional to the photodetector’s active area, while the response speed is inversely proportional—highlighting a tradeoff between sensitivity and bandwidth. The optical power handling is scaled with detector’s area due to thermal conductivity and optical power density limit.

Technical FAQ
Single mode, Multimode. Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
Wavelength: 1230-1620nm, 400-1000nm, 850nm. Check the Transmitters & Receivers passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
Share your wavelength, fiber type, connector, power handling and control requirements and we will qualify the matching configuration and part number.
