Fiber Driver® EM316SW-XY
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.
2.1 Features
This modular design supports a wide variety of module and port features. Some important features
are listed below.
• Copper 10/100Base-TX with full wire-speed capabilities
• Maximum packet size of 1916 bytes
• Auto-negotiation
• Half/full-duplex sensing
• MDI/MDIX detection
• Fault status propagation (LIN and FEFI) except in switch mode
• Management tools for status and module control
• Port status through front panel LEDs and module management
• Hot-swap support
The LIN, MDI/MDIX, and Loopback features are configurable, and each item is introduced below.
PN 1288003-001, Rev D2
1
Fiber Driver® EM316SW-XY
2.1.1 Loopback
Loopback tests and verifies the link integrity. It is available on the fiber optic ports (P2 and P3)
only, and it operates in all four operational modes.
Loopback directs received data on a port to the transmitter to test the fiber optic link end-to-end
from the remote converter.
The figure below illustrates loopback with a pair of EM316SW-XY modules. In the drawing, FO1
and FO2 refer to fiber optic ports P2 and P3.
Figure 1 -- Loopback on FO1 while FO2 is in normal operation
The two loopback switches (loopback and loopback2) correlate to the two converters on the
module. “Loopback” controls port P2 and “Loopback2” controls port P3. The switch settings
apply to operation in all operational modes. In Redundant Link mode, both the loopback
switches must be set to the same position (either both ON or both OFF) for supported operation.
PN 1288003-001, Rev D2

Fiber Driver® EM316SW-XY
2.1.2 Link Integrity Notification (LIN)
LIN is not available in switch mode.
A single DIP switch (LIN EN) activates LIN for the entire module except in switch mode. If this
switch is OFF, then LIN cannot be activated even through software management. In the other
operational modes, ports on the EM316SW-XY are paired as converters or repeaters. LIN
applies to each port pairing with mode considerations noted in the corresponding sections. In
Redundant Link mode, changing LIN status on any port adjusts all ports (P1, P2, and P3) to the
same setting. Port P4 is disabled in this mode.
When a link fault is detected on a paired port, LIN shuts down the transmitter on the partner port
to notify connected equipment dependent the lost link. This status propagation allows switches,
routers, and other link-state dependant devices to accurately react to link conditions.
With standard LIN operation (without FEFI), digital diagnostics traps are suppressed. The LED
indicates beaconing with regular flashes while a link is down and data activity with irregular
flickers otherwise. A beaconing port is considered to have no signal.
LIN is especially valuable in fault-tolerant designs.
2.1.3 LIN with Far End Fault Indication (FEFI)
The SFP ports support FEFI, which conforms to IEEE 802.3u 100BASE-FX specifications.
When an SFP port detects a link failure on its receiver, it sends an FEFI (Far End Fault
Indication) signal to the remotely connected device as notice of a link fault. It may also receive
an FEFI signal sent from the remote link partner, which causes it to disable the paired copper
Ethernet port transmitter.
FEFI is always enabled on the EM316SW-XY, but it is used only as requested by LIN and
configured through either DIP switches (FEFI and FEFI2) or management module
administration.
In Redundant Link mode, enable both FEFI DIP switches (FEFI=ON and FEFI2=ON) to use
FEFI with LIN. This configuration provides “1:1” link protection to the redundant link. The dualhoming configuration (separate remote optical devices) is not supported.
2.1.4 Redundancy
The EM316SW-XY redundant mode (discussed in the following section) pairs the two SFP ports
(P2 and P3) as a self-healing link based on signal detection. The switch-over time when the
active fiber link fails is very short, which can allow transparent failover.
LIN disables the Ethernet port P1 only if BOTH fiber channels fail simultaneously. Port P4 is
disabled in redundant mode.
PN 1288003-001, Rev D2

Fiber Driver® EM316SW-XY
2.2 Modes of Operation
The EM316SW-XY supports four different operational modes.
1. Dual Repeater (Fiber and Copper)
2. Dual Converter
3. Redundant Link
4. Switch (4-Port, mixed-media)
This section describes these modes and required DIP switch settings.
Select the operational mode with the DIP switches labeled MODE1 and MODE0, switches 5 and 6
on switch block 1 nearest the front panel of the module.
Redundant: fiber optic ports P2 & P3
Local: copper port P1
Unused: copper port P4

Fiber Driver® EM316SW-XY
2.2.1 Dual Repeater (Fiber and Copper)
MODE1 ON
MODE0 ON
Figure 2 -- Dual Repeater Mode
In Dual Repeater mode, the module acts as a pair of repeaters.
Fiber Optic repeater between 100Base-FX ports SFP-based interfaces
Copper repeater between 10/100 Base-TX ports RJ-45 copper interfaces
The copper repeater can be used as a distance extender in a copper infrastructure to extend a
link beyond the 300 foot (100m) limit. Each RJ-45 interface supports speed and duplex
matching and automatic MDI/MDIX detection. LIN applies to this configuration, as well.
With LIN enabled, loss of link at a port receiver disables the transmitter of the paired port. There
is no beaconing on an inactive link in Dual Repeater mode.
PN 1288003-001, Rev D2
5
Fiber Driver® EM316SW-XY
2.2.2 Dual Converter
MODE1 ON
MODE0 OFF
Figure 3 -- Dual Converter Mode
In Dual Converter mode, the module incorporates two independent “copper 10/100 to Fiber Fast
Ethernet converters” for the price of a single converter. This combination doubles the density of
a central office chassis, allowing up to 30 converters in a managed 16-slot chassis.
The first converter uses ports P1 and P2. The second converter uses ports P3 and P4.
With LIN enabled, loss of link at a port receiver disables the transmitter of the paired port.
Downstream switches, routers, and other link-state dependant devices can accurately react to
changing link conditions. This feature is especially valuable in fault-tolerant network designs.
The module supports both LIN and FEFI for link status propagation in Dual Converter mode. In
this mode, LIN offers two functional options.
1) The basic LIN (FEFI disabled) maintains backwards compatibility with all MRV Fast
Ethernet media conversion modules as well as the common Far End Fault Indication
(FEFI). The SFP transceiver beacons (transmits a periodic signal) if there is no signal
detected on its receiver. This signal notifies the other side about the detected problem.
2) A revised LIN (FEFI enabled), which uses the FEFI standard to notify the other side
about a problem in the receive fiber. Beaconing is not necessary in this case.
The revised LIN is recommended if the other side of the link supports FEFI. Use basic LIN if the
remote device does not support FEFI.
A single DIP switch controls LIN for both converters, so both will use either LIN enabled or
disabled.
PN 1288003-001, Rev D2

Fiber Driver® EM316SW-XY
2.2.3 Redundant Link
MODE1 OFF
MODE0 ON
Figure 4 -- Redundant Link Mode
In Redundant Link mode, the module acts as a copper to redundant fiber (100Base-FX)
converter. This configuration requires optical SFPs installed in ports P2 and P3 to support a pair
of redundant fiber optic paths. Ethernet port P4 is disabled in this mode; only description
commands will have any effect on P4. The Redundant Link mode provides “1:1” link protection.
Dual-homing is not supported.
In this mode, the EM316SW-XY can pass link status with LIN or with the industry standard Far
End Fault Indication (FEFI). Implementing both tools allows for backwards compatibility with the
full set of MRV Fast Ethernet media conversion solutions while supporting standard connectivity
to any standard Fast Ethernet fiber optic port.
With LIN enabled, loss of link at BOTH fiber ports (P2 and P3) disables the transmitter of the
access (Ethernet) port (P1). If one fiber optic channel fails while the other fiber optic channel is
operational, LIN does not interrupt the data. Downstream switches, routers, and other link-state
dependant devices can accurately react to changing link conditions. This feature is especially
valuable in fault-tolerant network designs. Set both DIP switches (FEFI and FEFI2) ON to
enable FEFI with LIN in Redundant Link mode.
The “select-link” command is enabled for ports P2 and P3 in Redundant Link mode to force a
port to active if it has an available link. There is no default or preferred port, so the first link
established becomes active. The “shutdown” command is not available for redundant ports P2
and P3.

Fiber Driver® EM316SW-XY
2.2.4 Mixed-Media Switch (4-Port)
MODE1 OFF
MODE0 OFF
Figure 5 -- Switching Mode
In Switch mode, the module acts a mixed-media Ethernet Switch with two 10/100Base-TX
copper interfaces and two fiber-optic SFP-based 100 Base-FX interfaces.
The mixed-media switch allows copper Ethernet traffic access to a linear fiber-optic Ethernet
network.
LIN is not supported in this mode.
