Orcave 2222

indoor unit of a microwave link with net transport capacity from 10 to 105 Mbps


Orcave 2222 is an indoor unit of a microwave link point-to-point with a transport capacity from 10 to 105 Mbps. It is suitable for middle sized links either last miles or backbones. Operations factors and reliability predetermine it for large usage by ISPs, data&voice operators and end users as well.

Main (fast) interface might be Ethernet 10/100 as well as E3. Up to 4 aside (slow) channels can be added, paired everytime - 2x E1 or 2x V.35.

Unit is equipped with QPSK and APSK de/modulation and has FEC (Reed Solomon) as well. This way is the reliability improved even in bad atmospheric conditions.

Orcave 2222 is built in RACK 2U high. Voltage is selectable 230V AC or 48V DC. Only one coax cable is used between ODU and IDU. Tx frequency depends on ODU, make your choice in related products (left column).

More technical oriented information you can find in Features.


  • net transport speed 10 - 105 Mbps
  • FEC - Reed Solomon and Viterbi
  • 1x main interface either Ethernet 10/100 or E3
  • up to 4x side channel E1 or V.35
  • full range tuneable Tx and RX
  • modulation scheme QPSK, 8APSK, 16APSK, 32APSK
  • system configuration by SW
  • remote monitoring with ability to set up all operating parameters


  • single HW for different capacity (gather speed is achieved by SW license only)
  • modular design, which enables full capacity usage by main and several aside channels
  • remote tuning minimizes radio interferences in a free band
  • easy to migrate to another frequency band
