Erbium Doped Fiber Amplifier

Erbium doped Fiber Amplifier (EDFA) is a portfolio of optical amplifiers designed for fiber lasers and fiber optic communication consisting of C- or L- Band signal light. 

The C-Band(conventional band) is the region between 1530-1565nm. Optical fibers shows the lowest loss in this region out of the 5 bands.

The L-Band(long-wavelength) is the region between 1565-1652nm and is the second lowest-loss wavelength band. It is an alternative when C-band is insufficient to meet the bandwidth demand. Common applications are Wavelength-Division Multiplexing and EDFA.

EDFAs has high energy conversion efficiency coupled with high gain and low noise. Desktop EDFA is easy to experiment with, allowing users to set pump current or output power from the front panel, as well as a more compact EDFA module for system integration. Both desktop EDFA and modular EDFA support on-computer software control or serial command control. 

At Simtrum, we provide for the following types as shown below:

TYPE

Description

C-band Series

L-Band Series

Single Channel

Amplification of   faint light signals to improve signal detection.

Typically used in -45 dBm to -25 dBm range

ü     

û   

Single Channel   Booster

Increases intensity   of laser light source.

Typically used in the -6 dBm to 3 dBm range or higher   power optical signal power boost, up to a saturated power of 26 dBm

ü     

û   

Polarization Maintaining   (PM)

Uses protection fiber optic system, allowing full protection bias

ü     

û   

High Power Polarization Maintaining

Unique multi-stage optical amplification design and reliable high-power laser cooling process, with the features of a normal   PM setup

ü     

ü   

High power Single Mode

Unique multi-stage optical amplification design and reliable high-power laser cooling process, in the transverse mode

ü     

ü   

Single In-Line 

Line relaying in fibres with the advantages of Pre-Amplifiers   and Booster-Amplifiers.

It is used to increase relay length or compensate for   branch losses in the corresponding single-point-to-multipoint portion of the   optical access network.

 

ü     

û     

Gain Flatten

Able to simultaneously amplify multiple wavelength signals   in the C-band while maintaining consistent gain across wavelengths with a   gain flatness of ≤ 1.5 dB

ü     

û     

Pulsed

Used in pimp and Nasser laser pulses which output peak   power laser pulses while minimizing the nonlinear effects of fiber optics

ü     

û     

EDFA (natural)

Typically covers 1570 to 1603 nm wavelength range, with the standard high gain and low noise.
