The ONS-SI-GE-LX-C is a 1 Gbps SFP transceiver supporting 1000BASE-LX at 1310 nm, designed for extended temperature ranges and fully compatible with Cisco ONS fiber-optic platforms.
This SFP is validated on Cisco ONS 15454, 15216, 15316 and 15327 series, ensuring seamless plug-and-play operation across supported Cisco Optical Networking Systems.
The module supports a fixed data rate of 1 Gbps, fully compliant with Gigabit Ethernet (1000BASE-LX) standards.
The transceiver operates at a 1310 nm wavelength, optimized for single-mode fiber links up to 10 km.
Over standard single-mode fiber (SMF), the module supports reaches up to 10 km at 1310 nm, depending on fiber quality and link margins.
Use single-mode fiber (SMF) with a core size of 9 µm. Multi-mode fiber can work with mode-conditioning patch cords but reduces maximum distance.
This SFP is rated for industrial-temperature operation from –40 °C to +85 °C, ideal for harsh environments and outdoor enclosures.
Yes. The ONS-SI-GE-LX-C is fully hot-swappable, allowing insertion or removal without powering down the host Cisco ONS device.
It uses an LC duplex connector, standard for single-mode SFP transceivers, providing reliable low-loss fiber connections.
Insert the SFP into an available SFP port on the powered-on Cisco ONS chassis until it clicks. The system will automatically detect and configure the module.
No additional OEM validation is needed. It is engineered for 100% compatibility and will be recognized as a native module by Cisco ONS software.
Typical power draw is 0.8 W maximum, ensuring low heat dissipation and minimal impact on Cisco ONS chassis power budgets.
Use Cisco IOS or ONS CLI commands like `show interface transceiver` to confirm link status, temperature, optical power, and vendor details.
It includes a one-year limited warranty covering defects in materials and workmanship. Extended coverage options are available upon request.
No. The 1310 nm 1000BASE-LX SFP is not DWDM or CWDM tuned. Use it on standard SMF links only; DWDM/CWDM requires wavelength-specific transceivers.
It matches Cisco specs for 1000BASE-LX performance, extended temperature, and compliance, often at a lower cost while maintaining full interoperability.
