DEV 7186 Alpha Outdoor RF over Fiber Chassis, up to 8 Channels

DEV 7186 Alpha Outdoor RF over Fiber Chassis, up to 8 Channels 

The DEV 7186 Optribution Alpha Outdoor Chassis is a compact, IP65-rated aluminum enclosure for deploying up to eight RF over fiber channels in harsh outdoor environments. It accommodates two Alpha optical transmitter or receiver modules, each supporting as many as four channels.

The configurable chassis supports standard and high-power L-band optical links, 10 MHz reference transmission, CWDM and 1+1 redundancy applications. RF interfaces are available with 50 Ohm SMA or 75 Ohm precision F female connectors. A separate position accepts a CWDM de-/multiplexer without using either optical-module slot.

Variable gain, RF sensing, optional LNB powering, signal recording, SNMP and the DEV Web Interface provide comprehensive monitoring and control. The DEV 7186 is interoperable with other DEV Optribution and Alpha RF over fiber products.
