Shenzhen N-NET Technology Co. Ltd

Model Number: NT-G2100SFP#6065M Brand Name: N-net Key Specifications/Special Features: 10/100/1000M 2SFP port ring fiber media converter1.OverviewThe NT-G2100SFP Gigabit SFP media converter provides 1 TP and 2 SFP ports to support conversion between 10/100/1000Base-T and 1000Base-X networkWith the two SFP ports, the NT-G2100SFP provides high reliability and flexibility in the media transmission distance from 550m to 100KM varying with SFP fiber modulesIt allows two working mode as belowFlexible drop-and-repeat or redundant path operationThe NT-G2100SFP model, with its 2 SFP ports, can easily be configured for either drop-and-repeat or redundant path operation
In drop-and-repeat mode, the NT-G2100SFP operates like a 3-port switch and can be used as a repeater with an electrical drop or simply as an optical repeater/extender
In this situation, it works in store and forward mechanism, and prevents packet loss with IEEE 802.3x flow control (full-duplex) and back pressure (half-duplex) function

In redundant path mode, the NT-G2100SFP will quickly switch to the second SFP port as a redundant path if the primary optical path experiences an optical cable failure
Also, if the primary destination port link is down, the module will forward the data packet to the redundant path providing a highly fault-tolerant solution for mission critical IP applications
