AMG4701ER-CWDMn Instruction
Sheet D16885-01.doc
Introduction
Unit Functional Schematic
The
AMG4701ER-CWDMn
transmits
Ethernet data to the
AMG4702ER-CWDMn
receive unit using a wavelength defined by
'
n'
in the CWDM
n
partno.
The example shown in the schematic is
where '
n'
= 7, i.e. the Tx wavelength is
1590nm.
It also receives Ethernet data transmitted
on any 1310nm or 1550nm band
wavelength from the
AMG4702ER-
CWDMn.

For CWDM wavelengths 11-14, ITU-T G652C or D fibre is recommended.
Optical Connection
The
AMG4701ER-CWDMn
is connected as illustrated below when used with an
AMG4702ER-
CWDMn
Ethernet Media Converter receive unit and external optical couplers, connected as a point to
point system over a single optical fibre.
