Imagine SELOPT-NET-SFP-MM SFP MODULE, MULTIMODE, FOR SELENIO...

• Full-duplex 155/622 Mb/s SONET/SDH optical interface (OC-3/STM-1, OC-12/STM-4)
• Two independent WAN interfaces per network module (option)
• Full-duplex 35/45 Mb/s PDH electrical interface (E3/DS-3)
• One GigE connection for Ethernet Bridging across WAN
• GFP/ATM Encapsulation
• Redundant SMPTE-2022 IP transport
• Up to 240 video channels, 16 VLAN IDs

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.
