IWA4718 C-Band DWDM
Variable Gain EDFA with Mid-Stage Access
Description
a. Idealphotonics IWA4718 series is a new generation C-Band DWDM
variable gain EDFA with mid-stage access bandwidth 1528~1564nm. It combines
best-in-class optical performance, state-of-art electronics, a feature-rich
control language, and an extremely compact
form factor to create the most versatile
performance-oriented amplifier on the market.
Third generation control electronics simplify complex optical functions
such as tilt compensation. It is composed of
variable gain pre-amplifier (PA)
and variable gain booster amplifier (BA). The gain of these two
amplifiers can be set in a certain range. There are access connectors between
the two amplifiers which can be used to access OADM, DCM and other optical
modules.
b. HA4720 VGA with MSA output power up to 18dBm , Gain range 16~28dB , mid
stage loss range 0~8.5dB . HA4720 can meet the C-Band 44 channels wavelength
DWDM channel systems and various technical requirements, can be widely used in
DWDM systems Intelligent Optical (ASON), optical add-drop Multiplexing (OADM),
and long lines of dispersion compensation.
Applications
• OADM
• DCM in over long trunk
• ASON
• Reconfigurable optical add/drop multiplexer (ROADM)
• Long-distance or ultra-long haul network between the city
