1.55

μm EAM/DFB-LD MODULE WITH SINGLEMODE FIBER PIGTAIL

DESCRIPTION

Module type FU-632SEA-x61MyyF is an electro-aborption

modulator integrated with 1.55

μm DFB-LD module with

single mode optical fiber.

This module is suitable to a light source in 2.5Gb/s digital

optical communication systems where the distance is

more than 640km.

This module is prepared in accordance with ITU-T

recommendation wavelength channel plan for Dense-

WDM transmission.

Note 1. Even if the thermoelectric cooler(TEC) is operated within the rated conditions, uncontrolled current loading or

operation without heat sink may easily damage the module by exceeding the storage temperature range.

Thermistor resistance

should be properly monitored by the feedback circuit during TEC operation to avoid

the catastrophic damage.
