The XFP-STM64-LH40-SM1550 is a 10G single-mode XFP module operating at 1550 nm with a reach of up to 40 km over LC duplex fiber.
This module supports single-mode fiber (SMF) with LC duplex connectors for long-distance links up to 40 km.
It delivers a line rate of 9.953 Gb/s to 11.3 Gb/s, fully compliant with 10G Ethernet and SONET/SDH standards.
Yes. It is compliant with the XFP MSA specification and hot-pluggable in any XFP-capable 10G switch or router.
It operates at a nominal wavelength of 1550 nm, ideal for long-haul single-mode transmission.
It supports distances up to 40 km over standard single-mode fiber at 9/10.3125 Gb/s line rates.
The optical transmit power ranges from –1 dBm to +3 dBm, ensuring robust link margins for 40 km spans.
Receiver sensitivity is –24 dBm at BER 1×10⁻¹², ensuring reliable detection over 40 km.
Yes. It features a built-in digital diagnostic monitoring interface (DDM) for real-time monitoring of temperature, voltage, and optical power.
The module operates reliably between 0 °C and +70 °C (commercial range) and can be customized for extended temperatures if needed.
It offers a power budget of at least 13 dB, accounting for fiber attenuation and connector losses over 40 km.
