For over 25 years CXR Larus has been a leading fiber optic equipment
supplier to the telecommunications community. We provide cost-efficient
optical solutions to everyone from major carriers to the smallest
enterprise application. Typical CXR Larus fiber optic products convert
electrical DS1 or E1 into optical signals for transport through single
mode or multimode fiber cable. These are used for the interconnection of
LANs and WANs, extending the local loop, or used in the customer premis
network in order to extend a LAN to LAN connection.

An end-to-end Model FT2ER Quad DS1 Fiber Optic Extension System is
comprised of the FT2ER circuit pack and mounting shelf at each terminal
end and the interconnecting fiber. A fully protected system requires two
FT2ER circuit packs at each terminal end. The units operate with either
single or multimode cable, with distances of up to 39 miles (63.3 kM).
They are also ideal in pedestal and CEV envrionments, and operate over a
temperature range of -40 to 75 degrees C.
