| AL-1250s
is one of the members of AirBridge, it is designed to
transmit the data with speed lower than 1250Mbps. There
are two VCSEL LASERs to be 1+1 backup with high power
and one APD detector with high sensitivity in AL-1250s,
which has a controller for power with three steps and
could transmit data for 100m～1500m.The features of AL-1250S
are as follows: |
- Support
to access any data with speed between 100Mbps and 1250Mbps;
- Support to relay any protocol data transparently, such as, STM-4/OC-4,
ATM, FDDI, FE, GbE, etc.;
- No warranty for wireless frequency is needed, prompt to mount with low
cost;
- Suitable for temporary or permanent use;
- The indicator for received power exists with ten steps;
- Satisfy
short distance or long distance application |
