DESCRIPTION
NEC's NX7302BA-CC and NX7302CA-CC are 1310 nm Fabry-
Perot (FP) laser diode coaxial modules with single mode fiber.
They have a Multiple Quantum Well (MQW) structure and a
built-in InGaAs monitor photo diode. These modules are ideal
as light sources for Synchronous Digital Hierarchy (SDH)
systems, STM-4 and short-haul S-4.1 ITU-T recommenda-
tions.
