General
The KGC-311 is a mode to mode optical fiber converter se-
ries which provide the following conversions:
1000BASE-SX MM fiber to/from 1000BASE-LX SM fiber
100BASE-FX MM fiber to/from 100BASE-FX SM fiber
Features
Complies with IEEE 802.3z 1000Base-SX/LX and IEEE
802.3u 100Base-FX standard
Provides media conversion between single mode and
multimode optical fiber media types
Supports both 1000Mbps Gigabit Ethernet fiber and
100Mbps Fast Ethernet fiber applications
Provides two SFP slots to support standard SFP fiber
transceivers
Transparent conversion to any type of packet frame
No packet length limitation
Provides LEDs for easy network monitoring
Center chassis installation : support installation in a
center chassis rack with benefits of central software
management, central power and redundant power
backup.
Diversified mounting support : desktop mounting, wall
mounting, optional Din-Rail support
Support wide range of single mode fiber options: short
reach up to long reach, Bi-directional single fiber, and
CWDM
Low power consumption
