Extralink SFP+ 10G SFP+ WDM modul 10Gbps 1270/1330nm single-mode 20km LC DOM pár

Extralink SFP+ 10G WDM 1270/1330nm single-mode module pair provides bidirectional 10 Gbps transmission over a single optical fiber using wavelength division multiplexing at 1270 nm and 1330 nm. Each LC-connected SFP+ transceiver supports up to 20 km reach on single-mode fiber and includes a digital optical monitoring (DOM) interface and a two-wire I²C serial channel for identification and diagnostics. The electrical interface meets SFI specifications and the receiver converts 10 Gbit/s optical signals to PECL/CML serial electrical outputs.

Advantages

The modules offer economical, space-saving bidirectional operation over one fiber, DOM support for real-time monitoring of optical power and laser parameters, and wide compatibility with 10 Gbps Ethernet, SONET/SDH and multiple optical channel rates. Their SFP+ form factor and standard LC connector simplify installation and compatibility with network equipment that supports SFP+ transceivers.

How to use

Install one module at each end of the fiber link, ensuring the correct wavelength orientation (1270 nm vs 1330 nm) so that transmit and receive directions are matched. Insert each SFP+ transceiver into the device’s SFP+ slot until it latches. Connect single-mode LC patchcords between the two modules. Enable DOM or check the host device’s diagnostics page to monitor optical power, laser current and other parameters. Configure the network equipment for 10 Gbps operation as required by your topology.

Recommendations

Use clean LC connectors and follow manufacturer guidelines for handling optical modules. Verify compatibility with your switch or router vendor’s SFP+ support list and perform link tests after installation to confirm correct wavelength pairing and acceptable optical power margins.
