Consistent optical output.
Professional DWDM SFP module.
The DWDM-SFPGE-1531-12 is an eSFP 2.5 Gbps DWDM optical module operating at 1531.12 nm, designed for single-mode fiber links up to 120 km with LC connectors.
This transceiver operates at the ITU-T DWDM channel wavelength of 1531.12 nm (channel 31).
It supports up to 120 km of single-mode fiber transmission without intermediate amplification.
The module is designed for single-mode (SMF) fiber and uses a duplex LC connector interface.
It supports a data rate of 2.5 Gbps and is compliant with the enhanced small form-factor pluggable (eSFP) specification.
The transceiver meets ITU-T G.694.2 for DWDM, IEEE 802.3, and SFF-8472 for digital diagnostics monitoring.
Yes, the module is hot-swappable, allowing insertion or removal without powering down the host system.
It operates reliably between –5 °C and +70 °C (industrial temperature range).
Insert the transceiver into a compatible eSFP slot, connect LC-terminated single-mode fibers, and verify link status via the host interface.
It is compatible with most switches, routers, and DWDM mux/demux systems supporting eSFP and 2.5 Gbps DWDM modules.
Use the SFF-8472 digital diagnostics interface to read real-time parameters such as optical power, temperature, and voltage.
Ideal applications include metro DWDM networks, long-haul data transport, and high-capacity fiber backbone links.
The module consumes less than 1 W of electrical power during normal operation.
Use high-quality single-mode fiber, maintain proper endface cleanliness, and monitor link margins via diagnostics.
It includes a one-year limited warranty, MTBF exceeding 1,000,000 hours, and conforms to Telcordia GR-468 for reliability.
