| MRV Products Fiber Driver-LD Modules  Fiber Driver-LD transponders are single slot modules that interface between the CWDM or DWDM multiplexers and the terminal equipment. These modules provide transparent light paths at ITU-T grid CWDM/DWDM wavelength, which can carry any data centric protocols at any rate from 2 Mbps to 2.7 Gbps, enabling carriers to mix different protocols such as SONET/SDH, Fast Ethernet, Gigabit Ethernet, Fibre Channel, ESCON, etc. in a same chassis. MRV offers a complete family of TDM (Time Division Multiplexing) access modules designed to boost wavelength as well as fiber utilization. The EM2009-EM4 ESCON Multiplexer supplies multiple channels of ESCON (via TDM) into DWDM or CWDM, increasing the number of ports in a single fiber by a factor of TDM implementation, thus increasing the efficiency of fiber use as well as saving precious physical space. A combination of the 4x ESCON Mux in the LD800/1600 chassis achieves extremely high levels of density - 128 ESCON services can be run over one fiber pair (with 32 wavelengths). The electrically based multiplexing allows for a significant cost reduction and higher fiber utilization when compared to a pure optical multiplexing solution. The ESCON Mux link fiber interface can be 850nm/1310nm or CWDM grid for direct connection to the CWDM Mux. The EM2009-GM2 allows for a significant cost reduction and higher fiber utilization when compared to pure optical multiplexing solutions. The EM2009-GM2 module aggregates 2 Gigabit Ethernet tributaries into a 2.5 Gbps aggregated uplink port. To optimize each port interface as needed, all ports use standard SFP (Small Form Pluggable) field-installable transceivers. Products |
