Product Description Ⅰ、Feature Raeturn Path Receiver supports up to four optical receiver modules in a 1Uhigh, 19” rack mount enclosure. Each receiving module is used to receive upstream optical signals and to transport return information to the optical distribution hub or headend. Each receiving module is designed to transform an optical signal from the node to an electrical RF signal for processing at a hub or headend location. Ⅱ、Technical Specification Optical Wavelength( nm) 1100~1600 Optical Input Power( dBm) -10~+2dBm Suggestion Usage Scope-6~0dBm Optical Return Loss(dB) >45 Fiber Connector FC/ APC SC/ APC Retutn Bandwidth(MHZ) 5~42、5~65、5~200 Flatness(dB) ≤ ±1.0 Output Impedance 75Ω Output Level( dBuv) ≥ 80dBuv( Optical Imput Power-6 dBm, Loss6dB) Optical Return Loss( dB) ≥14dB The electricity is even to regulate the scope 20dB CNR ≥51dB Operating Temperature(℃) 0~50 Store the temperature -25~65℃ Power Supply(AVC) AC160—265V、AC50HZ |
