Project Description
1×2(2×2) Single Mode WDM
980/1550nm and 1480/1550nm WDM are widely used in EDFA, Which can combine the pump power and optical signal into the Er-fiber.1310/1550 WDM can be used to combine or split 1310nm and 1550nm optical signals, which double the fiber transmission capability and ensure bi-direction communication in a single fiber.

- Above specification are for device without connector, and may change without notice. All parameters are tested at room temperature.
- Other specifications can be made on customer request.
- For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower. The pass optical power is 2 W only for connector added.
- If there is pulse application, please be sure to inform us of pulse energy and peak power.
- Insertion Loss around 1383nm (water peak) is counted in the specifications above.
