Cisco SFP-10G-LR= 10GBASE-LR SFP+ Transceiver Module (1310nm 10km SMF LC DOM)

The Cisco SFP-10G-LR= is a premier hot-swappable SFP+ (Small Form-factor Pluggable Plus) optical transceiver engineered for high-speed 10 Gigabit Ethernet connectivity. Compliant with the 10GBASE-LR industrial standard, this module operates over single-mode fiber (SMF) at a nominal wavelength of 1310nm, supporting long-range data transmission distances up to 10 kilometers (10km).

As a critical component for modern data centers, enterprise wiring closets, and service provider transport networks, the Cisco SFP-10G-LR= delivers low latency, exceptional electromagnetic interference (EMI) protection, and an ultra-low power consumption profile (typically 1W). It integrates seamlessly into Cisco Catalyst, Nexus, and routing platforms, ensuring flexible, energy-efficient, and robust network scale-up.

• 100% Guaranteed Compatibility: Pre-tested on actual Cisco switches (including Nexus 9000 and Catalyst 9300/9500 series) to eliminate "Unsupported Transceiver" system errors.

• Full DOM/DDM Support: Real-time Digital Optical Monitoring allows engineers to track laser temperature, supply voltage, Tx power, and Rx power instantly.

• Industrial-Grade Reliability: Equipped with top-tier 1310nm DFB lasers and PIN receivers for a minimized Bit Error Rate (BER) and prolonged operational lifecycle.

• Cost-Effective Network Scaling: Enjoy OEM-equivalent performance and strict quality control at a fraction of original brand prices, driving down your TCO (Total Cost of Ownership).

A: This is a frequent point of confusion for network infrastructure teams. The core difference lies in protocol support range and application focus:

• SFP-10G-LR=: This is the standard mainstream module. It supports Ethernet, OTN (Optical Transport Network), and Fibre Channel (up to 8G/10G SAN environments) protocols.

• SFP-10G-LR-S= (S-Class): This is the enterprise/economic version. Cisco removed non-Ethernet protocols to lower costs. It only supports 10G Ethernet and does not support FCoE or OTN.

• Verdict: If your deployment is purely for 10G switch-to-switch stacking or LAN links inside a data center, the S-Class (LR-S) offers better cost efficiency. If your infrastructure includes SAN storage networks or carrier-grade transport equipment, you must use the standard SFP-10G-LR=.

A: Direct deployment over MMF is highly discouraged. The SFP-10G-LR is structurally optimized for a 1310nm single-mode fiber core. Forcing it onto multi-mode fiber leads to massive modal dispersion and high optical attenuation, slashing reliable distances to under a few hundred meters. If you need 10G speeds over MMF (up to 300m), please select the SFP-10G-SR module. If you absolutely must use an LR module on MMF, you must deploy a specialized Mode Conditioning Patch Cord on both ends of the link.

A: No. LonRise transceivers are hard-coded with precise OEM EEPROM configuration files to emulate original Cisco signatures seamlessly. Switches recognize our modules as native hardware. In rare scenarios where strict IOS constraints are enabled on legacy platforms, you can bypass third-party vendor blocks instantly by executing standard Cisco CLI commands like "service unsupported-transceiver".

A: To safeguard your hardware against long-term optical degradation, adhere to these guidelines:

1. Dust Prevention: Fiber-optic end-faces are extremely sensitive to dirt and grease. Keep the protective blue dust caps securely attached until the precise second you insert the LC patch cables.

2. Avoid Receiver Saturation: The maximum input power limit (saturation point) for the SFP-10G-LR receiver is -0.5 dBm. If you are setting up short-range loopback testing or link runs under 1km, always integrate a 5dB or 10dB fixed optical attenuator into the link path. Failure to do so will permanently burn out the highly sensitive PIN photodetector.
