OFS-DM/OFS-DS Series

10/100M Ethernet Fiber Media Converters

OFS series Fiber Media Converters can convert Optical－Electric Ethernet signals between 10/100M UTP interface (TX) and 100M optical fiber interface (FX).  It can extend traditional 10/100M fast Ethernet to the distance of 120km through optical fiber link. It possesses stable performance and good quality by adopting latest IC packages from USA and Taiwan. 6 Group LED indicated lights could fully monitor the working conditions of Converters. It is easy for end-users to observe network operation. OFS series external power supply Converters could be used alone, or inserted to 14 slots Converters Rack supplied by OFS Crop. suitable for the use of Network Centre.

Main features

◆ Auto negotiation function allows UTP port to auto select 10M or 100M, and Full Duplex or Half Duplex.

◆ UTP port supports MDI/MDI-X auto crossover.

◆ Indicator function of link fault (LFP): When optical fiber or UTP is at fault, the converter could stop all the link.

◆ Multiple Optical Transceiver could be chosen: SC, ST or FC, singlemode / multimode

◆ Supporting 1600 bytes packet for management 

◆ Converter working mode could be chosen: Store and forward switch mode, Modified cut-through switch mode, or Converter mode.

◆ Internal Circuit of prevented thunder could greatly reduce damage of the converter caused by thunderbolt induction.

◆ Internal or External switching power: for users to choose.
