Introduction
SRB series optical receiver is a practical indoor type optical receiver designed to meet the network fiber renovation project. This product has 1 to 2 RF output ports. And set the optical AGC function when +2dBm ~ -6dBm when receiving the output can be maintained at 106dBµV above (dual); shell using cast aluminum shell.
Functional Features

| Note: Under the specified link loss conditions, configure 59 PAL-D analog TV channel signals within the 550MHz frequency range, and transmit digital modulation signals within the 550 MHz to 862MHz frequency range. The level of the digital modulation signal (within an 8 MHz bandwidth) is 10dB lower than the carrier level of the analog signal. When the optical receiver input optical power is-6 dBm, measure C/CTB, C/CSO, and C/N. The nominal RF output level is at the 862 MHz frequency point, with the actual output being 10dB lower. | |||
