VCL-E1 (G.703) Fiber Optic Modem
Product Overview
Application Diagram
The VCL-E1 Fiber Optic Modem provides the user
the capability to establish communication between two E1
nterfaces over an optical fiber link.
It establishes a secure, long range data fiber link between
routers, multiplexers and other E1 devices.
The primary application for the VCL-E1 (G.703) Fiber Optic
Modem is to establish point-to-point fiber link at ranges
longer than any copper modem can achieve. The clock
options are Internal / External / Slave Clock - three clock
mode option.
(G.703)
/
FE1 I
Safety Warnings !!!!
For Testing : Always Install Optical Attenuators.
For Distance of less than 10 Kms Optical Attenuators
must be installed on the Optical Links. Otherwise, the
Optics will be Permanently Damaged.
