Philippine SFP Optical Module DML

DML-based SFP optical modules are available in the Philippines for single-mode fiber applications, supporting distances up to 20 km with 1310 nm wavelength and DDM functionality.

Overview of DML SFP Modules

Directly Modulated Laser (DML) SFP modules are optical transceivers that use a laser diode directly modulated by the electrical signal. They are commonly used in single-mode fiber networks for switches, OLTs, and servers. Typical specifications include:

• Wavelength: 1310 nm
• Data Rate: 1.25 Gbps (for standard SFP) or up to 10 Gbps (for SFP+)
• Transmission Distance: Up to 20 km
• Connector Type: Dual LC
• Features: DDM (Digital Diagnostic Monitoring) for real-time monitoring of temperature, voltage, and optical power
