Applications
Used in telecommunications and
datacommunication systems, from
medium to high speed for Long-Reach
and Ultra-Long-Reach applications,
Alcatel 1914 DMC modules offer a
wide case operating temperature
range from - 40 to + 85 擄C.
Part of the Alcatel 1900 DMC family,
the Alcatel 1914 DMC module is
particularly suited for all types of Long-
Haul, Metro and Access optical links
such as :
. Fiber In The Loop (FTTB, FTTC,
FTTH...)
. Digital transport links
. Private optical networks
. Intra and interoffice links
