Substation Hardened Ethernet
Copper to Fiber Media Converters
Links Ethernet Line
GarrettCom models 3340, 3350, 3344 and 3354 are hardened fiber optic
links that convert 10Base-T
 Ethernet
from twisted pair copper to 10Base-FL or Single-mode fiber
optics.
GarrettCom models 3440, 3450, 3442, 3452,
3444 and 3454 are hardened fiber optic links that convert
100Base-T Ethernet from twisted pair copper to 100Base-FX,
100Base-SX or Single-mode fiber optics.
Dymec Links media converters are Class 1, Div 2 certified for
use in hazardous locations in the US and Canada. The Class 1,
Div 2 certification mark allows use of Dymec Links in ignitable
environments requiring spark-free operation. This is a
requirement for many customers, particularly those in petroleum
and petrochemical applications, where hazardous ignitable
environments abound.
These links are stand-alone mounted and require no
programming or set up. Simply mount the Link in an appropriate
location and connect power. DYMEC Links are powered from various
sources. The standard models accept 90 to 250 Volts ac or dc.
Optionally, these Links can also be ordered for 12 or 24 to 48
Volts dc. The power supplies are surge withstand protected to
both IEC 63000 and IEEE C37.90 standards.
