RFOptic’s multi-channel solutions

RFOptic’s multi-channel solutions consist of a series of multi-link enclosures. These analog multi-link RFoF solutions are designed to help customers deploy multi-channel solutions. RFOptic’s multi-link RFoF solutions are flexible enough to accommodate between 2 and 8 links RFoF links, in a single enclosure. All the enclosures support Remote Management and Control over Fiber (IFL) options. We are working intensively to extend its multi-channel portfolio of both indoor and outdoor enclosures.

A multi-link solution comprises of two enclosures: One enclosure housing the receive modules and the other the transmit modules.  In case bidirectional support is needed, each enclosure can house both Tx and Rx modules. It can be also a mixed of transmitters and receivers in each enclosure (indoor/outdoor). In some solutions additional components like CWDM mux and demux are deployed.

RFOptic provides a variety of rack mountable and outdoor enclosures based on the customer’s needs. Typically, the transmit modules are housed in the outdoor enclosure near the antenna and the receive modules are housed in a 1U chassis situated inside the control room.

The rack mountable chassis consists of a 19” 1U and can house up to 8 modules (Tx or Rx). It has SMA or K connectors and FC/APC or SC/APC or LC/APC optical connectors and can be customized based on the customer’s needs.

Our outdoor enclosure is IP-65 rated and has weather-proof MPO optical connectors and N-Type RF connectors. Power and Data connectors are hermetically sealed as well to provide complete rugged outdoor solutions.

If there is a constraint on the fiber utilization, an optical MUX is used to form a WDM aggregation of multiple signals on a single physical fiber running between the transmit and receive modules.

RFOptic’s multi-link enclosures can be managed and monitored locally or remotely. Remote management is done using RFOptic’s SNMP/HTML platform and enables the user to:

  • View events/alarms, and manage / control the status of each individual Tx and Rx module.
  • Troubleshoot by measuring the optical level and perform end-to-end RF tests.
  • Customize the S21 and NF of each link by adjusting RFoF modules internal LNA and attenuators

Multi-link solutions are are especially suited for satellite applications where several links run in parallel. In case of a failure of one of the main channels, the system can switch automatically to a redundant channel. Such solutions is applicable for 1U generic enclosure. The system can be provided with gain control at the receiver side in order to tune the gain as required. Furthermore, multi-link solutions are also popular with systems integrators that need to extend the coverage of 2-way radio systems into areas with poor over-the-air coverage.
