 EM316GMX 
- Gigabit Multimode Extenders
EM316GMX 
- Gigabit Multimode Extenders
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.
 Optical 
Protection Switch-EM316OSSH
Optical 
Protection Switch-EM316OSSH
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.
 EM316-xSW 
- 10/100 Ethernet Switches
EM316-xSW 
- 10/100 Ethernet Switches
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.
 EM316xSF 
- Single Fiber Media Converters
EM316xSF 
- Single Fiber Media Converters
The 
Fiber Driver® familys 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.
 EM316SC & PASCLCAS - Splitter/Combiner
EM316SC & PASCLCAS - Splitter/Combiner
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.
 EM316E1MUX4 
- E1 Fiber Multiplexers
EM316E1MUX4 
- E1 Fiber Multiplexers
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.
 EM316T1MUX4 
- T1 Fiber Multiplexers
EM316T1MUX4 
- T1 Fiber Multiplexers
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.
 WDM22
WDM22
E1 
/ T1 & Fast/Gigabit Ethernet over a Single Fiber
Combining 
Fiber Driver® WDM and Splitter/Combiner technology, the E1 and T1 WDM22 modules 
combine separate voice and data channels onto a single strand of fiber. The EM316FE1SF 
and EM316GE1SF models merge E1 (2.048Mbs) and Ethernet (100 Mbps and 1000 Mbps 
respectively), while the EM316FT1SF and EM316GT1SF combine T1 (1.544Mbs) and Ethernet 
(100 Mbps or 1000 Mbps). The units effectively quadruple available fiber capacity. 
What would normally require separate dual-fiber links, one for an E1/T1 connection 
and one for an Ethernet connection, instead takes only a single strand of fiber.
