OVERVIEW
The YKW-SK121 series comply with IEEE 802.3/ab Gigabit Ethernet standard. It supports two types of media for network connection such as 10/100/1000 Base-Tto 1000 Base SX/LX and connects these two types of segments to operate smoothly
YKW-SK121 series can be used in 16 slot chassis as plug in module
YKW-SK121 series Fiber Media Converter transforms 1000Base-T (Copper Gigabit) media to 1000Base-SX/LX (Fiber Gigabit) media and vice versa. The 1000Base-T port supports full-duplex Gigabit connection at wire speed with RJ45 connector. The fiber Gigabit connection supports shortwave (SX) or long wave (LX) laser optic with multi-mode or single-mode SC type connector.

This converter will give your Copper Gigabit connection the ability to interface with fiber connection over a distance up to 80 km!
10/100/1000 means,  that media converter that converts the electrical signal of a 10/100/1000 Ethernet signal from copper to fiber. This solution will offer a low-cost integration option for network managers who want to migrate from 10/100 networks to Gigabit Ethernet. Gigabit only switches can now be connected to 10/100 networks without the need to upgrade the 10/100 side, allowing network managers to add new equipment gradually
