Ruijie 10G SFP+ LR Transceiver 1310nm 10km, DDM, ITM003404

Introduction: Ruijie 10G SFP+ LR Transceiver — key features at a glance

The Ruijie XG-SFP-LR-SM1310 (SKU: ITM003404) is a compact, hot-pluggable SFP+ optical transceiver engineered for 10 Gigabit Ethernet (10GBASE-LR) links over single-mode fibre. Operating at 1310 nm and supporting link distances up to 10 km via duplex LC connectors, this module combines industry-standard interoperability, low power consumption and Digital Diagnostic Monitoring (DDM/DOM) for real-time status reporting. With a suggested retail price of $99.99, the module is positioned as an affordable, vendor-branded option for data centres, campus networks and service-provider deployments that require reliable 10G single-mode uplinks.

Detailed specifications and what they mean for your network

Understanding the technical specifications helps determine whether the XG-SFP-LR-SM1310 is the right fit for your application. Below are the core specifications and the practical benefits they provide.

• SFP+ form factor (hot-pluggable):SFP+ is widely supported across modern switches, routers and network interface cards (NICs). The hot-pluggable nature means you can install or replace modules without powering down the host device, minimising downtime during upgrades or maintenance.
• Data rate — 10.3125 Gbps (10G):Designed for full 10G Ethernet, the transceiver supports high-throughput uplinks and server connections. This is suitable for aggregation links, uplinks between access and core switches, and direct server connections where 10G bandwidth is required.

• Wavelength — 1310 nm (DFB Tx / PIN Rx):The 1310 nm wavelength is standard for 10GBASE-LR, providing low attenuation and stable performance over single-mode fibre up to the specified reach.
• Reach — up to 10 km over SMF:A 10 km reach covers campus backbones, many metro segments and common data-centre interconnect distances without needing regeneration or additional hardware.
• Connector — duplex LC:Duplex LC is the industry standard connector type for SFP/SFP+ modules and is compatible with common patch panels and fibre cabling infrastructure.
• Transmit and receive characteristics:Typical transmit power (~0.5 dBm, min around −8.2 dBm) with receiver sensitivity < −12.6 dBm gives a healthy optical budget for 10 km links in typical installations. DDM/DOM support provides real-time monitoring of optical transmit/receive power, temperature, voltage and bias current for proactive troubleshooting.

• Standards compliance:Conforms to IEEE 802.3ae, SFF-8431 and SFP+ MSA, ensuring interoperability with compliant vendor hardware.
• Power consumption — ≤ 1.5 W:Low power draw helps reduce total power use in dense chassis or server environments where many optics may be deployed.
• Operating temperature:Manufacturer lists −40°C to +85°C; however, some resellers note a commercial variant rated 0–70°C. Confirm the temperature rating with the supplier if deploying in extreme environments.

Benefits: Reliability, monitoring and value

• Vendor-branded assurance:As a genuine Ruijie module, it typically comes with tested compatibility for Ruijie gear and better vendor support compared with anonymous generic compatibles.
• Real-time diagnostics:DDM/DOM (SFF-8472) enables network engineers to monitor optical parameters and detect issues early, reducing troubleshooting time and improving uptime.
• Low power and compact size:The SFP+ form factor and ≤1.5 W power make it suitable for dense deployments where heat and power budget matter.
• Cost-effective 10G single-mode option:With a suggested price around $99.99, it represents a competitively priced branded transceiver for many enterprise and service-provider use cases.

Use cases and scenarios where the product excels

The Ruijie 10G SFP+ LR transceiver is designed for any environment that needs reliable 10G single-mode optical links. Typical deployments include:

• Data-centre aggregation and server connectivity:Use the module for 10G uplinks from top-of-rack switches to aggregation or spine switches, or for direct 10G links between servers and switches where single-mode fibre is used.
• Campus backbones:For campuses with buildings separated by distances up to 10 km, this transceiver supports stable, high-bandwidth links between buildings and network cores.
• Service-provider and metro edges:When tested, OEM-branded modules with DOM monitoring are often preferred by service providers for operational visibility and vendor support.
• Longer runs within enterprise sites:Facilities with single-mode fibre infrastructure that require reliable 10G connections without the overhead of multimode or wavelength conversion.
• Migration and upgrades:Organisations migrating from 1G to 10G or consolidating aggregation layers will find this module useful for gradual capacity upgrades without replacing cabling.

Comparisons with similar products on the market

When selecting a 10G SFP+ LR transceiver you will typically encounter three broad categories: OEM-branded modules (like Ruijie), compatible vendor-branded modules (Cisco, Juniper, HPE, etc.) and third-party generic compatibles. Here’s how the Ruijie unit stacks up:

• Interoperability:OEM modules from Cisco or Juniper are guaranteed to work with those vendors' devices and may include vendor-specific features. The Ruijie module is likewise a tested match for Ruijie equipment and targets customers in that ecosystem.
• Cost:Ruijie-branded modules are often less expensive than Cisco OEM optics but still offer vendor-level testing and support — a middle ground between premium OEM pricing and budget compatibles.
• Support & warranty:OEM transceivers generally come with formal manufacturer warranty and support. Check Ruijie or your reseller for the exact warranty terms; some third-party listings do not include comprehensive coverage.

• Reliability and testing:Generic compatibles are low-cost alternatives but vary widely in testing and long-term reliability. A Ruijie-branded module typically offers greater assurance of compatibility and operational stability.
• Diagnostics & DOM accuracy:Quality branded modules tend to provide more consistent DDM readings, which can be critical for proactive network management.
• Risk of vendor lock or port disabling:Some switch vendors implement checks that reject non-OEM optics. Manufacturer-branded modules reduce the risk of such issues.

Installation, safety and commercial notes

• Installation:The SFP+ module is hot-pluggable — follow your switch or server vendor guidance for insertion and removal. Ensure the device firmware supports SFP+ modules and that transceiver firmware locking policies are understood.
• Optical safety:Avoid looking into active fibre ends and follow Class 1 laser safety guidance. Use appropriate fibre handling practices to prevent damage to connectors and transceivers.
• Compliance and environmental:The module lists RoHS compliance and Class 1 laser safety. CE/UKCA marking was listed as insufficient data in some reseller notes — confirm regulatory markings with the supplier if required for your market.
• Warranty and procurement:Warranty and support terms may vary by reseller. Confirm the warranty and return policy prior to purchase, and verify the module temperature rating if you plan to deploy in extreme environments.

Customer impressions and typical feedback

There are no specific public customer testimonials included here, but the common themes reported by network engineers when deploying reputable branded SFP+ LR optics are useful to consider:

• "Reliable 10G links with stable DDM readings — made troubleshooting easier and reduced mean time to repair."
• "Lower failure rates compared with unknown generic modules in high-density racks."
• "Good value for a branded module — cheaper than some OEM optics but with vendor-grade interoperability."

These representative impressions reflect typical expectations for a quality branded transceiver: dependable links, useful diagnostics and predictable behaviour in multi-vendor environments.
