The AF4B Series are 1.48m m high power pumping laser diode modules designed for Er-doped optical amplifiers. Each laser is packaged in a 14-pin butterfly package with optical isolator, monitor photodiode, and thermo-electric cooler.

Applications include submarine and terrestial WDM networks and FTTx/CATV systems.

• High optical output power (120-400 mW)
• Low power consumption
• Built-in optical isolator
• Internal monitor PD, thermo-electric cooler, and thermistor
• SMF or PMF fiber out pigtail type
