SEL-2NET1

Module
Each Selenio SEL-2NET1 module is factory-configured with one active WAN interface for use with an E3, DS3, OC3, or STM-1 network. The Selenio chassis supports up to four SEL-2NET1 or SEL-MDX modules.

Option Keys
Optional software keys can be used to enable an OC-12/STM-4 interface, a second WAN interface, and local data networks to be bridged across WAN links.

Front Module Connectivity
The Selenio SEL-2NET1 application module is internally interconnected with the controller modules for 100Base-T for control and monitoring and 1000Base-T for video/data applications. The primary and backup reference signals are also distributed.

Back Module Connectivity
The Selenio SEL-2NET1 networking application module provides connectivity for two HD-BNC PDH receiver connectors, two HD-BNC PDH transmitter connectors, two Rx/Tx SFPs (SFPs not included), and two RJ-45 Ethernet connectors.

SFPs
Various SFPs are available for a variety of applications.
