Description
The ETP01 series is a low capacitance transient
surge arrestor designed for protection of high
debit rate communication network. Planar
technology used combines a high surge capability
to comply with Telcordia GR1089 Intrabuilding
and ITU-T K20/21, and low capacitance to avoid
distortion of high speed signals such as Ethernet.
Applications
This series can meet subscriber and central office
requirements.
■ Protection against telecommunications surge
standards on:
– 10/100 Mbps Ethernet
– T1 / E1 line cards
