Description

High-compatibility 10GBASE-LX4 XENPAK transceiver for mixed MMF/SMF environments. Uses 1310 nm 4-lane WDM to reach up to 300 m on multimode and up to 10 km on single-mode with a duplex SC interface—ideal for extending legacy MMF backbones to 10GbE without new fiber runs.

Features

- Mixed-fiber flexibility: runs on both MMF and SMF
- Extended MMF reach up to 300 m without fiber upgrades
- 10 km reach on SMF for campus and metro links
- Standards-based 10GBASE-LX4 interoperability
- Field-proven XENPAK form factor for legacy 10G platforms

Warranty

All products sold by XS Network Tech include a 12-month warranty on both new and used items. Our in-house technical team thoroughly tests used hardware prior to sale to ensure enterprise-grade reliability.

FAQs

Q: Will this work on any 10G port?
A: It requires a native XENPAK slot (or a supported XENPAK adapter on certain platforms). Check platform compatibility before purchase.

Q: Does this module support digital diagnostics (DOM/DDM)?
A: LX4 XENPAK modules typically do not provide DOM/DDM. Monitor link status via the host platform.

Q: Can I use OM3/OM4 fiber?
A: Yes, LX4 operates in the 1310 nm band and supports MMF; typical reach on 50 µm MMF is up to 300 m. Always validate with your fiber plant and platform limits.

Q: Is the connector LC or SC?
A: Duplex SC.
