Mini Line LR 92 HFC MicroNode, upstream 1310 nm
Category : Optical Network Terminations
The LR 92 is an extremely low-noise optical receiver. Because of the high output level it is particularly well suited for direct house distribution. The measurement point can be displayed through the LED and the DC, in the range of -8 to +1 dBm. The return path transmission is ensured through the 1310 nm Fabry-Perot laser. Its compact design requires a minimum amount of space, and the built-in measuring socket allows control of the signals.
- Compact HFC fiber node for FttB and FttH networks
- Cost efficient Fabry-Perot laser at 1310 nm for upstream transmission
- High output level enables direct in-house distribution
- Extremely low receiver noise for good reception quality at low input levels
- Manual adjustment of optical level compensation for maximum flexibility
- LED and DC test point for monitoring of optical input power
