      Technical FAQ: PL2000B Multiport EDFA<\/h2>\n
      \n

      Q1: What makes the PL2000B a “cost-effective” choice?<\/h3>\n

      A:<\/strong> The PL2000B uses an economical internal design<\/strong> that reduces the initial investment without compromising core performance. It utilizes premium components like Lumentum lasers<\/strong>, making it the best balance of price and carrier-grade quality.<\/p>\n<\/div>\n

      \n

      Q2: Can the output power be adjusted on the PL2000B?<\/h3>\n

      A:<\/strong> Yes. The PL2000B allows for adjustable output power<\/strong> within a range of -10 to +0.5dBm<\/strong>. This can be easily configured via the front panel touchscreen or the remote Web\/SNMP interface.<\/p>\n<\/div>\n

      \n

      Q3: How does the Automatic Pump Shutdown mode work?<\/h3>\n

      A:<\/strong> To protect the hardware, the PL2000B triggers an Automatic Pump Shutdown<\/strong> when the input optical power is too low or unavailable (LOS). This prevents the pump laser from operating under unsafe conditions, extending the system’s life.<\/p>\n<\/div>\n

      \n

      Q4: What is the lead time for small batch orders of 1-2 units?<\/h3>\n

      A:<\/strong> For small quantities of 1 to 2 pieces, our standard lead time is only 5 days<\/strong>. We also support customized labeling and logos with a minimum order quantity (MOQ) of just 1 piece.<\/p>\n<\/div>\n<\/div>\n
