A Perle SR-100-SFP-XT DIN Rail Media Converter transparently connects UTP copper to fiber in industrial grade operating temperatures -40F to +167F (-40C to +75C). Equipment found in traffic management, oil and gas pipelines, weather tracking, industrial and outdoor applications must function in temperatures that cannot be supported by a commercial based media converter. This Fast Ethernet Media Converter is ideal for use with industrial devices subjected to harsh environments and severe temperatures such as security cameras, wireless access points, alarms, traffic controllers, sensors and tracking devices.

  • Extend the data transmission distance of IP-based devices by connecting their 100Base-TX Copper interface to fiber.
  • Extend the distance of an existing industrial network by linking CAT5/6/7 cabling to multimode or single mode fiber.
  • Protect Ethernet data from EMI noise and interference by inter-connecting your copper-Ethernet devices over fiber in industrial plants.

The pluggable fiber optics port allows for flexible network configurations using SFP transceivers supplied by Perle, Cisco or other manufacturers of MSA compliant SFPs.

Network Administrators can “see-everything” with Perle’s advanced features such as Auto-Negotiation, Auto-MDIX, Link Pass-Through, Fiber Fault Alert, and Loopback. This allows for more efficient troubleshooting and less on-site maintenance. These cost and time saving features, along with a lifetime warranty and free worldwide technical support, make the SR-100-SFP-XT Fast Ethernet Media Converter the smart choice for IT professionals.

SR-100-SFP-XT Fiber Media Converter Features: 100Base-TX to 100Base-X

Fully designed to operate in extreme temperatures

Perle SR-100-XT Industrial Media Converters only use components that are fully qualified and rated to operate in -40F to +167F.

There are other products on the market that claim to operate at -40F to +167F however, they use “commercial-grade” components that have not been qualified by the manufacturer (OEM) to operate at the claimed temperature ranges. When “commercial-grade” parts are exposed to extremely high or low temperatures, product failures are inevitable. For example, integrated circuits on the PCB overheat causing premature failures. Under-rated connectors do not allow for proper contact between the device and the cables. These failures eventually stop all data communications in these high and low temperature environments.

By choosing Perle you can be confident you will not be subjected to these failures.

DIN Rail Enclosure Easily mount on a DIN rail or inside distribution boxes using native DIN Rail enclosure with grounding clip. No need for add-on brackets.
Auto-Negotiation The media converter supports auto negotiation
on the fast ethernet 100Base-TX interface.
Auto-MDIX Auto-MDIX (automatic medium-dependant interface crossover) detects the signaling on the 100Base-TX interface to determine the type of cable connected (straight-through or crossover) and automatically configures the connection when enabled. With Auto-MDIX enabled, either a straight-through or crossover type cable can be used to connect the media converter to the device on the other end of the cable.
Link Pass-Through With Link Pass-Through the state of the 100Base-TX receiver is passed to the 100Base-X transmitter to make the media converter appear transparent to the end devices that are connected. In addition, if Far-End Fault is enabled the media converter can turn off the 100Base-TX transmitter when a FAR-End Fault is received.

Using Link Pass-Through with Far-End Fault minimizes data loss when a fault occurs. Should a fault occur, the end devices have the indication of a failure available to them making trouble shooting easier.

Far-End Fault (FEF) The media converter implements the 802.3 standard for Far-End Fault for the indication and detection of remote fault conditions on the 100Base-X fiber connection. With Far-End Fault enabled the media converter transmits the Far-End Fault Indication over the 100Base-X fiber connection whenever a receive failure is detected on the 100Base-X fiber connection. The media converter continuously monitors the100Base-X fiber connection for a valid signal.

The action the media converter takes on receiving a Far-End Fault Indication is dependent on the Link Pass Through switch setting.

Duplex Full and half duplex operation supported.
Pause (IEEE 802.3xy) Pause signaling is an IEEE feature that temporarily suspends data transmission between two devices in the event that one of the devices becomes overwhelmed. The fast ethernet media converter supports pause negotiation on the 100Base-TX copper connection.
VLAN The media converter is transparent to VLAN
tagged packets.
Remote LoopBack The media converter is capable of performing a loopback on the fiber port.

Hardware Specs

Hardware Specifications: SR-100-SFP-XT Media Converters

Input Supply Voltage Triple voltage 12 / 24 / 48 VDC (9.6 – 60 VDC) input supporting:
a) 2 x Terminal Block power input and
b) 1 x T-Bus power input
Current 0.09 A (@ 24VDC)
Power Consumption 2.16 watts (@ 24VDC)
Power Connector Dual input Terminal Block and/or T-Bus
Power / TST This green LED is turned on when power is applied to the media converter. Otherwise it is off. The LED will blink fast/slow when in Loopback test mode or hardware error.
Fiber link on / Receive activity (LKF) On: Fiber link present. Blinking slowly: Fiber link disabled because of copper link loss. Blinking quickly: Fiber link present and receiving data. Off: No fiber link present
Copper link on / Receive activity (LKC) On: Copper link is present. Blinking quickly: Copper link present and receiving data. Blinking slowly: Copper link disabled because of fiber link loss. Off: No copper link present
Switches – accessible by sliding the chassis open
Dip Switches accessible by sliding open the chassis
Auto-Negotiation Auto (Default – Up): In this mode of operation the media converter will negotiate Ethernet parameters on the copper connection. This will ensure the most optimal connection parameters will be in effect. If the copper link partner does not support Auto negotiation, the media converter will default to 100 Mbps and Half Duplex mode.

Off: Auto Negotiation should only be turned off, if the copper link partner does not support Auto Negotiation. When the Auto Negotiation switch is set to the OFF position, the media converter will operate at 100 Mbps and Full Duplex mode.

Smart Link Pass-Through Smart Link Pass-Through (Default – Up): In this mode, the link state on one connection is directly reflected through the media converter to the other connection. If link is lost on one of the connections, then the other link will be brought down by the media converter. If the installation has a media converter on both ends of the fiber link and both are setup for Link Pass-Through, then a loss of copper link on the far end device will propagate through both media converters and will result in a loss of copper link at the near end device. This would, therefore, resemble a direct copper connection.

Standard Mode (Down): In this mode, the links on the fiber and copper sides can be brought up and down independently of each other. A loss of link on either the fiber ports or copper ports can take place without affecting the other connection

Pause Auto (Deafult-Up): When Auto Negotiation has been set to Auto, the media converter will use this setting for its Ethernet parameter negotiation on the copper connection.

Half: The media converter will not negotiate support for the Pause feature.

Loopback Disabled (Default-Up): The loopback feature is disabled. This is the normal position for regular operation. The switch must be set to this position for data to pass through the media converter.

Enabled: This is a test mode. All data received on the receive (RX) fiber connection is looped back to the transmit (TX) fiber connection. The state of the copper is not relevant and no data or link status is passed through to the copper side.

Far-End Fault (FEF) Enabled (Defualt-Up): If the media converter detects a loss of fiber signal on the fiber receiver, it will immediately send a FEF on the fiber link. This notifies the fiber link partner that an error condition exists on the fiber connection. If the remote media converter is set up for FEF, and the local media converter is set up with Link Pass-Through, a loss of fiber link on either the transmit or receive line will be passed through to the local copper connection to notify the connected device. If the media converter has been set to Link Pass-Through mode, the effect will be the same as FEF since the link loss on the fiber receiver will bring down the copper link, which will in turn cause the transmit fiber link to be brought down.

Disabled: The media converter will not monitor for or generate Far End Fault.

Fast Ethernet to IP Cameras

Connect IP Cameras to Fast Ethernet Backbone
Extend the reach to IP cameras using industrial fiber media converters. Security cameras are typically installed in remote locations where extremely high or low temperatures are a concern — ceilings, rooftops, light poles, along fences, pipelines and transit routes.

Stand-alone Extended Temperature Media Converters are placed at the remote end connecting cameras with copper interfaces to fiber optic cabling. The fiber can extend the distance using single mode or multimode fiber back to a control center. A media converter chassis located in the data closet at the control center accepts the fiber signal, converts it, and connects to the copper equipment at the main site.

Fast Ethernet Fiber to Wireless Access Points

Connect Wireless Access Points to Fast Ethernet Backbone
Extend the reach to wireless access points ( AP ) using fiber media converters. When a company deploys a wireless network in their office or large warehouse, APs need to be set up throughout the facility to ensure complete coverage for reliability. The network manager will likely need to extend further than the 100 meters allowed by copper cable to reach many of the APs.

When APs are used in industrial environments where extremely high or low temperatures are a concern, Stand-alone Extended Temperature Media Converters are placed at the remote end connecting APs with copper interfaces to fiber optic cabling. The fiber can extend the distance using single mode or multimode fiber back to a control center. A media converter chassis located in the data closet at the control center accepts the fiber signal, converts it, and connects to the copper equipment at the main site.
