Description
The AddOn QSFP28 EDFA Preamplifier (ADD-QSFP28-EDFA-PREAMP-17DB) is a high-performance, hot-pluggable optical amplifier designed to boost the sensitivity and reach of C-band DWDM networks. Delivering a nominal gain of +17 dB and supporting input power from -30 dBm to -10 dBm, this compact preamplifier enhances signal levels prior to detection, improving overall link performance and optical budget in dense wavelength-division multiplexing applications.
Engineered for SFF-8661 compliance and QSFP28 form factor, the unit integrates built-in control circuits for stable operation, low power consumption, and high reliability. Featuring a duplex LC/UPC interface and AGC/APC operation modes, it ensures seamless integration with existing fiber infrastructure. Qualified to Telcordia GR-1312-CORE standards, RoHS compliant, and fully hot-pluggable, this EDFA preamplifier is ideal for high-capacity optical transport systems, metro and long-haul networks, and data center interconnect applications.
