The CEBx10(EML) series is a cost-effective solution for 10Gb/s digital

optical signal transmission.The modules consist of a multi-quantum-well

DFB laser device with 1550nm nominal emission wavelength and a

monolithically intergrated electro-absorption(EA) modulator.It is to

operate at a bit-rate of 10Gb/s for OC-192 and metro transmission

with an excellent pedigree of reliability.It is well suited for short,

intermediate and extended reach applications up to 20,40

and 80km respectively.Careful control of the output signal for

minimum“chirp”allows the CEB510 to provide superior performance

and long reach over spans of standard single mode fiber.

The hermetically sealed 7pin package with a GPO connector contains

a high-speed EML,optical isolator,back facet monitor diode,thermistor

and thermoelectric cooler(TEC )for precise control,The incorporated

TEC keeps the laser chip at a well-controlled temperature.This allows

the device to operate over a case temperature range of 0℃ to 70℃.
