Installed in a high density Perle Media Converter Chassis, Perle's feature rich CM-100MM Fast Ethernet Fiber to Fiber Managed Media Converter Module enables transparent fiber extension of 100Base-FX multimode fiber to 100Base-FX multimode or 100Base-LX/EX/ZX/BX single mode fiber.
Perle's advanced features make the end to end fiber link completely transparent. This allows for more efficient troubleshooting and less on-site maintenance. When used with a Media Converter Management Module in the chassis, configuration and monitoring of the fiber ports can be performed. In addition, a lifetime warranty and free worldwide technical support make Perle's CM-100MM Fast Ethernet Fiber to Fiber Managed Media Converter Modules the smart choice for IT professionals.
For those environments requiring a medium to large-scale deployment of media converters, a centralized platform that simplifies the configuration, administration, monitoring, and troubleshooting of this gear is recommended. PerleVIEW Device Management software is a multi-user, Windows server-based application that delivers this level of Enterprise-grade solution.
Whether you need to extend multimode to multimode or multimode to single mode, Perle has an extensive range of CM-100MM Fast Ethernet Fiber to Fiber Managed Media Converter Modules to meet your fiber conversion requirement.

Backup and Restore |
Provides fast and easy module replacement. Management module will always save a copy of the media converter configuration and will restore this configuration automatically to the media module when it is detected in the slot. |

|
Far-End Fault (FEF) |
|
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 media converter is transparent to Pause frames. |
Signal Regeneration |
Signal Regeneration maintains signal integrity and allows for maximum fiber to fiber connections without degradation. |
Cascading |
Media Converters can be cascaded. Two or more Media Converters can be chained in a link to achieve even greater distances. |
VLAN |
The Media Converter is transparent to VLAN tagged packets. |
Remote Loopback |
The Media Converter can perform a loopback on each 100Base-X fiber interface. |

Indicators
Power / TST
This green LED is turned on when power is applied to the media converter. Otherwise it is off. The LED will blink slowly when in Loopback test mode.
Fiber link 1 / Receive activity (LK1)
This green LED is operational only when power is applied. The LED is on when the 100Base-X link is on and flashes with a 50% duty cycle when data is received.
Fiber link 2 on / Receive activity (LK2)
This green LED is operational only when power is applied. The LED is on when the 100Base-X link is on and flashes with a 50% duty cycle when data is received.
Switches: On-Board (If Auto/Switch strap is set to Switch)
Link Pass Through
- Enabled (Default) - When the state of the receiver is changed on one of the 100Base-X interfaces it is reflected on the other 100Base-X fiber transmitter.
When a Far-End Fault Indication is received on the fiber interface the 100Base-TX transmitter is turned off. When the Far-End Fault Indication is cleared the transmitter is turned back on. - If disabled, the 100Base-X fiber interfaces operate independently. Far-End Fault indication on the 100Base-FX fiber interface has no effect on the other interface.
Far-End Fault (FEF)
- Enabled (default) - The media converter transmits the Far-End Fault Indication over the fiber connection whenever a receive failure is detected. The media converter continuously monitors the fiber connection and clears the Far-End Fault Indication condition when a valid signal is received.
- When Disabled, Far-End Fault Indications are not transmitted regardless of the condition of the receive signal on the 100Base-X fiber connection.
Remote Loopback #1
- Disabled (Default - Up)
- Enabled - The 100Base-X receiver is looped to the 100Base-X transmitter. Link #2's fiber transmitter is taken off the interface.
Remote Loopback #2
- Disabled (Default - Up)
- Enabled - The 100Base-X receiver is looped to the 100Base-X transmitter. Link #1's fiber transmitter is taken off the interface.

Application Diagrams
High Density Fiber Distribution from Fiber Switch Equipment at Corporate Headquarters
In this enterprise campus application, up to 18 Perle CM-100MM Multimode to Single mode Media Converters are installed in the MCR1900 Media Converter Chassis. The 19th slot in the chassis is filled the MCR-MGT Management Module. All media converts in the chassis are managed by SNMP, Telnet or an internet browser interface. A remote fiber enabled Ethernet switch is connected directly to the central MCR1900 Chassis. Another S-100MM Fiber to Fiber Media Converter is connected to a remote office switch. In all cases, multimode or single-mode fiber can be used. Fiber links can be extended up to 120km using single-mode fiber.
Managed Ethernet over Fiber Links
Manage your multimode to single mode or multimode to multimode link with an MCR200 chassis housing a media converter and management module. Ideal for use in managed networks with low density fiber applications, this Managed Media Converter is connected across a fiber link to a remote media converter. The copper or fiber link on the managed standalone unit can provide vital information and status to network management tools such as SNMP.
Fast Ethernet Multimode Switch to Multimode Switch
Extend the network distance between two Multimode Fiber Switches
Two Fiber to Fiber Media Converters can extend the distance between Fiber Switches across a fiber link up to 120km in length.
Single Mode / Single Fiber
When Single Strand fiber is used, a pair of Single Fiber Media Converters is needed for the fiber to fiber conversion. Perle Single Fiber Media Converters are also referred to as “Up/Down” models. For example the CM-100MM-S1SC20U (“Up”) and CM-100MM-S1SC20D (“Down”), shown below, must be used in pairs. An “Up” must be matched with a “Down” peer to deal with transmit and receive frequencies separately.
CM-100MM-S1SC20UCM-100MM-S1SC20D
The majority of installations for single mode fiber media converters are of the “dual connector” or “dual fiber” type where one fiber connection is used for transmit, the other for receive. These are physically “crossed” to match up the Transmit/Receive links.
However, to reduce costs, or where there are limits on available fiber, WDM technology may be utilized. WDM uses separate transmit and receive frequencies to communicate on a single fiber strand. WDM technology relies on the fact that optical fibers can carry many wavelengths of light simultaneously without interaction between each wavelength. Thus, a single fiber can carry many separate wavelength signals or channels simultaneously.
So remember, if Single Strand fiber is used, you will need an “Up” Media Converter on one side and a “Down” Media Converter on the other for fiber to fiber conversion.
Perle offers a wide variety of Single Fiber (“Up/Down”) Media Converters to connect 10BaseT, Fast Ethernet and Gigabit to single fiber. Whether you need Managed or Unmanaged, Standalone or Modular Chassis Based, 20km or 120km, Perle has the right model to meet your fiber conversion requirement.
