TRR7800L Return Optical Receiver: 1U, 4 independent receiver modules serve for 128 RFPON mininodes low to -27dBm input power

Summarize

TRR7800L Return Optical Receiver as an important access devices to two-way HFC network, transform the return optical signals to RF signals output. It is standard 1U chassis integrates 4 independent receiver modules, it can receive 128 ways return optical signals from Lootom`s RF PON MiniNodes or services for 128 RFoG optical network units (ONU)-MiniNode.

TRR7800L sensitivity up to -27dBm, meets the different optical link design. Front panel LCD displays the receiver`s work status and parameters, ease of local operation and monitoring, in additional, providing SNMP network management interface, meets the network management national standard, comply with SCTE-HMS and IEC standards.

Features

·Adopt imported high-quality optical receiver device for photoelectric conversion
