CM-110 Managed Fast Ethernet Media and Rate Converter

In this enterprise campus application, up to 18 Perle CM-110 10/100 Ethernet to Fiber 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. A standalone S-110 Media Converter converts the fiber to Ethernet in a fiber-to-desktop application. Another S-110 Fiber Media Converter is connected to a remote office Ethernet switch. In all cases, multimode or single-mode fiber can be used. Fiber links can be extended up to 120km using single-mode fiber.

The use of chassis-based media converters is a cost effective means in providing fiber connectivity in a campus network. By consolidating Ethernet to fiber conversion in a rack mount media converter chassis, various types of fiber links can be brought into a single wiring closet platform. This simplifies deployment and maintenance and also provides a scalable means to grow your network as needed.

Manage your copper to fiber 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.

Extend the network distance between two Ethernet Hubs
A pair of 10/100 media converters can extend the distance between hubs across a fiber link up to 120km in length.

Extend the network distance between legacy 10Mbps copper Ethernet to Fast Ethernet infrastructure
A pair of 10/100 media converters can extend the distance between a legacy 10Mbps device to a Fast Ethernet switch across a fiber link up to 120km in length.

Extend the network distance between two Ethernet half-duplex hubs
A pair of 10/100 media converters can extend the distance between hubs across a fiber link up to 120km in length. They also isolate the collision domains, associated with half-duplex, from crossing the fiber link.

Extend the network distance between an Ethernet half-duplex hub and a full-duplex switch
A pair of 10/100 media converters can extend the distance between a half-duplex hub and a full-duplex switch across a fiber link up to 120km in length. They also isolate the collision domains, associated with half-duplex, from crossing the fiber link. In this scenario, the media converter connected to the switch must be forced to half-duplex.

Extend the network distance between legacy 10Mbps copper Ethernet devices
A pair of 10/100 media converters can extend the distance between two legacy 10Mbps devices across a fiber link up to 120km in length.

Connect copper ports over a single fiber strand ( also referred to as “Bi-Directional” BiDi )
When Single Strand fiber is used, a pair of Single Fiber Media Converters is needed for the copper to fiber conversion. Perle Single Fiber Media Converters are also referred to as “Up/Down” models. For example the CM-110-S1SC20U (“Up”) and CM-110-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.

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 copper 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.
