2 Module Introduction
The Fiber Driver EM316SW-XY is a highly configurable multi-function module that can perform the
functions of hundreds of less sophisticated devices. The SW-XY can operate in four modes. Each of
these applications is described later in this section.
• Repeater
• Converter
• Redundant Fiber Link
• Switch
The SW-XY features two RJ-45 copper Ethernet ports (P1 and P4) and two SFP sockets (P2 and P3).
SFP transceivers are available from MRV to support virtually any standard fiber optic or copper
Ethernet protocol.
