Pluggable Amplifiers
Ian McClean, Product Manager, Coherent

Optical amplifiers are commonly integrated with transmit/receive optics enabling optical signal powers to overcome high modulator losses and to extend reach in both telecom and DCI networks.  Traditional discrete solutions using Erbium Doped Optical Amplifiers or Semiconductor Optical Amplifiers are now being incorporated into pluggable modules either as distinct amplifiers or integrated with transceiver optics and controls supporting disaggregation and reducing equipment complexity. Realising such compact designs within such challenging operating environments requires development of solutions that can be implemented in compact form factors whilst maintaining performance, cost and reliability.  Challenges and solutions are assessed for the primary amplifier technology based on Erbium Doped Fibre.
