The LX GbE SFP Optics Module (SKU 331-5272-C) is a Dell Networking–compatible, 1Gbps small form-factor pluggable transceiver with an LC connector designed for long-reach single-mode fiber links.
The 331-5272-C module supports gigabit Ethernet (1.25 Gbps) transmission rates, delivering reliable throughput for network uplinks and aggregation.
This module uses single-mode fiber (SMF) and features a duplex LC connector for secure, low-loss optical connections.
It supports distances up to 10 kilometers over single-mode fiber at 1310nm, ideal for metropolitan and campus backbones.
It’s interoperable with Dell Networking switches and routers, as well as third-party devices from Cisco, HP, Juniper and more that support IEEE 802.3z SFP specifications.
Yes, the 331-5272-C module is fully hot-swappable, allowing insertion or removal without powering down your network equipment.
The module operates at a nominal wavelength of 1310nm, optimized for long-distance single-mode transmission.
Simply insert the module into an SFP port until it clicks, then connect your LC fiber patch cable; the device will auto-negotiate link parameters.
Yes, the 331-5272-C is fully interchangeable with OEM and compatible third-party SFP modules adhering to the same IEEE standards.
Yes, it supports DOM for real-time monitoring of optical power, temperature, voltage and laser bias current via standard SFF-8472.
The module operates reliably between 0°C and 70°C (32°F to 158°F), suitable for standard data center environments.
Use clean single-mode fibers, proper LC connectors, maintain bend radius, and monitor link parameters via DOM to prevent signal loss.
Typical use cases include data center uplinks, campus backbone aggregation, metropolitan area networks (MANs) and long-haul connections.
LX modules operate at 1310nm for up to 10km over single-mode fiber, whereas SX modules use 850nm for short-reach multimode links and EX extend beyond 10km.
The 331-5272-C module offers an MTBF exceeding 1 million hours, ensuring high reliability and minimal downtime.
Yes, it supports IEEE auto-negotiation and low-power idle modes to optimize energy consumption and link stability.
