Dependable industry grade eSFP.
The OSC040N03 is an industrial-grade eSFP optical transceiver module designed for single-mode fiber links up to 40 km at 1310 nm wavelength.
This transceiver operates at a 1310 nm wavelength, ideal for long-distance single-mode fiber communications.
The OSC040N03 supports transmission distances up to 40 km over standard single-mode fiber.
It uses an industry-standard LC duplex connector for reliable fiber coupling and low insertion loss.
The module provides a transmit power range of –5 to 0 dBm and a receiver sensitivity down to –37 dBm, yielding a 32 dB power budget.
It supports STM-1 (Synchronous Transport Module level-1) protocol at 155.52 Mbps, suitable for SDH networks.
Yes, it is fully compliant with the SFP MSA (Multi-Source Agreement) and works with any compatible SFP slot supporting 1310 nm modules.
The module operates reliably from –40 °C to +85 °C, meeting industrial temperature requirements.
Simply insert the transceiver into an empty SFP slot until it clicks, then attach LC-terminated single-mode fiber cables.
It draws power from the host device’s +3.3 V SFP power rail with a typical consumption of <1 W.
Yes, it features DDM per SFF-8472 for real-time monitoring of optical power, temperature, voltage and bias current.
Yes, its industrial-grade design and wide temperature range make it suitable for harsh and outdoor installations.
It is compliant with CE, FCC, RoHS and SFP MSA standards, ensuring safety and interoperability.
