Home / Inquire about tunable optical modules DML
DWDM tunable optical modules are advanced devices used in dense wavelength division multiplexing systems. When discussing optical transceiver parameters, modulation schemes are a key consideration, and the transmitter modulation method is specified in the datasheet of some optical modules, as shown in the figures below: • The transmitter laser modulation mode is marked as EML in the Moduletek 25G ER. This laser is also called a distributed-feedback laser diode (DFB) since it uses a distributed feedback structure. A DML uses a single chip with a simple electrical circuit design, so it can be an optimal choice for a compact circuit configuration with low. In optical modules, EML (Electro-absorption Modulated Laser) and DML (Directly Modulated Laser) are two common laser technologies.
