Fiber optic Question and Answer:

What are Media Converters
Media Converters are devices that simply receive data signals from one media, convert and transmit them to another other media. For example, media converters can convert signals transmitted on a copper cable to signals that run on fiber. Since Media Converters function as physical layer networking devices, they remain completely transparent to other networking devices and any upper-level protocols.

More about Media Converters
Since a media converter is a physical layer networking device, it:

• simply converts data from one medium to another on a bit-by-bit basis
• doesn't look at addresses or other data
• doesn't recognize or react to collisions

Fiber Driver® copper to fiber media converter modules from MRV make it easy to merge legacy copper network elements with new or existing fiber optic infrastructure, allowing LAN communications to be extended to distances of up to 130 km or more. In addition, the Multimode Extender (MX) technology found in select Fiber Driver products breaks the transmission barrier of multimode fiber with link distances of up to 10 km.

Copper to multimode and copper to single mode solutions are available for Ethernet, Fast Ethernet, Gigabit Ethernet and Copper Gigabit Ethernet, OC-3/STM-1, DS3 and E3. (Additional Ethernet copper to fiber solution are provided by our signal repeater and switch modules.

The Fiber Driver® collection of Multimode to Single Mode converters allow network managers to connect between Multimode and Single Mode fiber. Conversion to Single Mode fiber can extend the transmission distance to over 100 km. Protocols covered by this group of modules include SONET OC-3 and Gigabit Ethernet.

Multimode to Single Fiber Single Mode modules can be found in the group of Single Fiber modules.

The EM316T1 and the EM316E1 modules of the Fiber Driver® family are designed to extend the distance and transmission reliability of T1 (1.544Mbps) or E1 (2.048Mbps) traffic. These units convert the electrical signals to optical signals and transmit them over distances of up to 10 km on Multimode fiber, or distances of up to 100 km on Singlemode fiber. The EM316T1 and EM316E1 are transparent to the framing format, and support AMI or B8ZS (T1) and HDB3 (E1) line codes, respectively. They include an internal elastic buffer to remove jitter from the transmitted data. Six LED indicators aid in monitoring and trouble-shooting this module. A management agent is incorporated on the module to enable management in conjunction with the Fiber Driver EM316NM management card. As part of the Fiber Driver family, the EM316T1 and EM316E1 modules fit in all Fiber Driver chassis types, support local and remote loopback tests, and can be used to interconnect between any T1 or E1 devices. Among the types of T1/E1 devices that can be connected by these modules are PBXs, multiplexers, video CODECS, routers, network servers, and ATM/frame relay switches. Benefits include extended distances, improved quality of transmission, better security, remote management capability, and high density.

The MS104 products are 4-port switches, which are targeted for SOHO, FTTH, and other applications where a few 10/100BaseTX devices need to be concentrated and connected to the network by fiber connections. The family members differ from each other by the type of fiber optic ports connection they accommodate, with a choice of multimode fiber, singlemode fiber, single fiber operation, different wavelengths and power levels as well as different connector types (DSC, SC and MTRJ).

The MS105 products are 5-port switches, which are targeted for SOHO, FTTH, and other applications where a few 10/100BaseTX devices need to be concentrated and connected to the network by fiber connections. The family members differ from each other by the type of fiber optic ports connection they accommodate, with a choice of multimode fiber, singlemode fiber, single fiber operation, different wavelengths and power levels as well as different connector types (DSC, SC and MTRJ).

The MM04 product line is a 4 port E1 or T1 multiplexer/demultiplexer that transmits over a fiber optic link. The products are standalone (1U), 19" rack mountable (half-size devices). The optical fiber interface is available in a number of standard fiber connections and has optional redundant optical connections. The chassis is available with universal AC power supply (100-240v) or DC power supply (36-60v) and and in option of redundant power supply.

MM04 devices support four (4) link interfaces and are available for E1 or T1 configurations with connections for RJ-48 (E1/T1 balanced). In long haul mode the interfaces possess usable receive sensitivity of 0 dB to -43 dB for E1 and 0 dB to -36 dB for T1 which allow the device to operate with 0.63 mm (22AWG) cables at distances up to 2.5 km (E1) and 6000 feet (T1).

Each E1/T1 port is designed to meet regulatory compliant solutions such as for circuit protection against surges and AC lightning, which is essential for long haul E1/T1 lines

The Fiber Driver® Gigabit Multimode Extender applies unique technology that allows the transmission of high-speed signals over Multimode fibers to distances much longer than the standard. This allows the use of high-speed backbone protocols over fiber that was originally used for FDDI.

Fiber optic cables for FDDI applications were typically laid in 2 km increments, since that was the distance limit for FDDI and Fast Ethernet on Multimode fiber. But with today's new high-speed backbone protocols, Multimode fiber's physical characteristics result in a maximum distance of 550 meters,.

The Fiber Driver Gigabit Multimode Extender offes a solution that is interoperable with all standard Gigabit Ethernet equipment. It carries Gigabit Ethernet data on existing Multimode fiber (FDDI graded) to distances of up to 2 km guaranteed. Depending on the quality of the fiber, links of up to 6 km are possible.

The Fiber Driver® Optical Protection Switch from MRV (model number EM316OSSH) makes creating a redundant optical link easier and more affordable than ever before. Designed to provide full path protection for mission critical networks, the module is capable of automatically switching between a primary and secondary (backup) link in 10 ms or less in the event of a fiber cut or transponder failure.

As an all optical device performing no optical-electrical-optical (OEO) conversion, the EM316OSSH remains protocol independent and accepts all wavelengths from 1260 nm to 1630 nm, making it suitable for virtually any application, including WDM path protection. The module can provide 1+1 protection in resilient point-to-point or Optical Unidirectional Path Switched Ring (O-UPSR) deployments.

The Fiber Driver® family includes three types of switch modules: three-, four-, and six-port Ethernet/Fast Ethernet switches. Switch modules are used to link between 10Mbps and 100Mbps or Half to Full Duplex mode. Switch modules offer a combination of 10/100Base-TX ports and 100Base-FX ports. They separate between Ethernet collision domains and filter local traffic from propagating to the rest of the network.

The Fiber Driver® family’s Single Fiber modules use unique technologies, which provide the ability to combine transmit (TX) and receive (RX) signals onto a single fiber strand. This effectively doubles the available fiber in a network, and eliminates the need for additional fiber installation. The Fiber Driver Single Fiber modules employs Single wavelength bi-directional technology in order to combine the TX and RX on the single strand.

Splitter/Combiner technology provides the ability to propagate two signals, transmit (TX) and receive (RX), over a single fiber strand using the same wavelength. The Fiber Driver® Splitter/Combiner modules, and Splitter/Combiner cables for GBICs and SFPs effectively double the availability of fiber in a network. They are fully passive devices that operate at a specific wavelength, and remain protocol and network transparent.

A pair of Splitter/Combiners add a power loss of only up to 7 dB for SM fiber and 9 dB for MM fiber. Angled Polished Connectors (APCs) are used at the link connections to eliminate cross-talk.

The Fiber Driver® E1 Fiber Multiplexer from MRV Communications transmits four E1 data channels across a fiber optic trunk in a Point-to-Point (PtP) configuration. Each line interface consists of a HDB3 encoder/decoder, and a receiver with equalizer for reliable data and clock recovery. The device also includes a crystal-less jitter attenuator which, depending on system requirements, can be set in the transmit (TX) or receive (RX) path. Line distances from 0 to 100m are supported. Line protection is designed to meet Telecordia GR-1089 standards. The Fiber Driver E1 Fiber Mux is G.703 interface and G.704 framing compliant.

The Fiber Driver® T1 Fiber Multiplexer from MRV Communications transmits four T1 data channels across a fiber optic trunk in a Point-to-Point (PtP) configuration. Each line interface consists of a B8ZS, or AMI encoder/decoder as applicable, and a receiver with equalizer for reliable data and clock recovery. The device also includes a crystal-less jitter attenuator which, depending on system requirements, can be set in the transmit (TX) or receive (RX) path. Line distances from 0 to 100 m are supported. Line protection is designed to meet Telecordia GR-1089.
