DESCRIPTION
NEC's NX7304BG-CC and NX7304CG-CC are 1310 nm Mul-
tiple Quantum Well (MQW) structured Fabry-Perot (FP) laser
diode coaxial modules with single mode fiber. These modules
are ideal as a light source for ITU-T recommended Synchro-
nous Digital Hierarchy (SDH) systems, for fiberoptic commu-
nications such as SONET and for digital transmission.
