Description
DSL03 is designed to protect DSL line drivers
against surges defined in worldwide
telecommunication standards. This device
protects line drivers of various systems such as
ADSL and VDSL. The low capacitance makes it
suitable from ADSL to VDSL2 data rates.
DSL03 is able to survive severe conditions even
when used with downgraded or oscillating gas
tube.
