NEC's NX7301BA-CC and NX7301CA-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 a light source for Synchronous Digital Hierarchy (SDH)
systems, STM-4, intraoffice I-4, and STM-1, intraoffice I-1,
short-haul S-1.1 ITU-T recommendations.
