product description
  The HWA4500 series is a next-generation variable gain fiber amplifier that is the most powerful and versatile variable gain fiber amplifier on the market today. It uses the most outstanding optical performance, the most advanced electronic technology, and the most complete software features. Superior transient suppression technology and thermal management control technology enable many complex optical functions to be realized, making it the most versatile multi-functional fiber amplifier on the market today.
  The next generation variable gain fiber amplifier consists of a variable gain preamplifier (PA), and a variable gain power amplifier (BA), a two-stage amplifier. The gain of the two-stage amplifier can be independently set within a certain range. There is an access connector between the two amplifiers, which can be used for Mid-stage Access, such as Optical Add/Drop Multiplex Module (OADM), Dispersion Compensation Module (DCM) and optical modules for other applications.
  The HWA4500 is a version with no intermediate level access (Without Mid-stage Access). The product meets the communication technical requirements of C-Band 44 wave or 88 wave DWDM system, and is widely used in long-distance and ultra-long-distance transmission networks. Due to its full functionality, it can be used as a line amplifier, preamplifier, and power amplifier.
