Introduction to the Ruijie XG‑SFP‑AOC3M and its key features
Ruijie XG‑SFP‑AOC3M — 3 metre 10G SFP+ Active Optical Cableis a purpose‑built short‑reach interconnect designed for modern, dense networking environments. As a 3 m Active Optical Cable (AOC) with SFP+ form‑factor plugs at both ends, it supports 10.3125 Gbps (10G) links between switches, servers and NICs. Key selling points include hot‑swappable SFP+ connectors, DDM/DOM diagnostics for link visibility, a slim and lightweight construction that improves rack airflow and cable management, and low typical power consumption (≈ 1 W). The cable is RoHS compliant and rated for normal data center operating temperatures, typically 0°C to +70°C.
Detailed description of specifications and benefits
The XG‑SFP‑AOC3M is engineered for short‑reach connectivity where reliability, density and thermal efficiency matter. Its technical highlights include:
- Model and form factor:XG‑SFP‑AOC3M in SFP+ form factor, compatible with SFP+ host ports.
- Data rate:Supports 10.3125 Gbps (10G) for full 10 Gigabit Ethernet performance.
- Connector:SFP+ to SFP+ plugs — hot‑swappable for simple installation and replacement.
- Length and media:3 m active optical cable using multi‑mode fibre and typical 850 nm optics for short‑reach links.
- Diagnostics:DDM/DOM support offers real‑time monitoring of optical power, temperature and other link parameters.
- Power and efficiency:Typical AOC power consumption ≈ 1 W — significantly lower heat generation than many active copper alternatives.
- Environmental compliance and temperature range:RoHS compliant and rated for typical operating temperatures of 0°C to +70°C.
- Applications:Optimised for switch‑to‑switch and switch‑to‑server interconnects in adjacent racks and dense data centre topologies.
Benefits you can expect when deploying the XG‑SFP‑AOC3M include improved rack airflow due to the cables slim profile, simpler cable management in high‑density environments, and the convenience of hot‑swappable SFP+ plugs that reduce service time during upgrades or maintenance. Built‑in DDM/DOM diagnostics enable proactive monitoring and faster fault finding, reducing mean time to repair (MTTR) for network teams.
Use cases and scenarios where the product excels
The Ruijie 3 m 10G AOC is best suited to environments where short, reliable, high‑speed links are required and cable density is high. Typical scenarios include:
- Top‑of‑rack (ToR) switch to aggregation switch links:Adjacent racks in a row often require many 10G links. The 3 m length is ideal for these paths, avoiding excess cable slack while keeping connections tidy.
- Switch‑to‑server connections in dense compute racks:When multiple servers in a rack connect to a single ToR switch, lightweight AOCs reduce congestion and improve airflow, which helps cooling efficiency.
- Switch stacking or short spine links:Where 10G bandwidth is needed between nearby switches, AOCs deliver predictable performance with low latency and reduced cabling bulk.
- Temporary test or staging environments:Hot‑swappable SFP+ plugs make the cable useful for lab and staging setups where rapid reconfiguration is common.
- Environments prioritising energy and thermal efficiency:With approximately 1 W typical power per AOC and a slim profile, deploying optical AOCs can lower heat load compared to certain copper alternatives with higher power dissipation or larger harnesses that impede airflow.
Comparisons with similar products in the market
When evaluating the XG‑SFP‑AOC3M, it helps to compare it against three common alternatives: passive copper DACs (direct attach copper), active copper DACs, and third‑party or vendor‑branded SFP+ optical transceivers plus fiber patch cables.
- AOC vs passive twinax DAC:Passive copper DACs are typically cheaper at very short distances (0.5 m–3 m) and draw no active power, but they are bulkier and can obstruct airflow. AOCs like the Ruijie unit are slimmer, improve cable management, and offer native optical isolation — useful where EMI immunity is desired. AOCs also provide DDM/DOM diagnostics, which many passive DACs do not.
- AOC vs active copper DAC:Active copper DACs extend reach and support host optics emulation, but they generally consume more power and still suffer from similar bulk issues compared with optical AOCs. Ruijies typical power of ≈ 1 W is low for an active device, and the optical medium benefits cable routing and airflow.
- AOC vs discrete transceivers + MMF patching:Using standalone SFP+ transceivers with separate MMF patchcords offers maximum flexibility and vendor neutrality, but adds connectors, fibre slack and additional points of failure. AOCs are an integrated, lower‑complexity alternative that reduces connector count and typically simplifies installation in dense racks.
- Vendor compatibility and brand comparison:Major brands such as Cisco, Arista, Mellanox (NVIDIA), Finisar and Huawei also supply 10G AOCs. The core technical differences are often minimal for same‑category AOCs (length, form factor, DDM support). The critical considerations are compatibility with your host equipment (some vendors implement port locking) and the availability of vendor approvals if you require guaranteed interoperability. Ruijies XG‑SFP‑AOC3M offers standard SFP+ signalling and DDM, but you should confirm host device compatibility where vendor locking is a concern.
Customer feedback and reviews
There are no specific official customer testimonials included with the product record. However, feedback themes commonly reported by network teams using 10G AOCs such as the Ruijie XG‑SFP‑AOC3M typically include:
- "Clean installation and improved airflow" — installers frequently praise the slim form factor and tidy cable runs compared with bulkier copper alternatives.
- "Reliable short‑reach performance" — operations teams often report stable 10G links with low latency and straightforward diagnostics via DDM/DOM.
- "Plug‑and‑play convenience" — hot‑swappable SFP+ plugs and integrated AOC design reduce time to deploy or replace links in production racks.
These illustrative comments reflect the practical benefits expected from an AOC of this specification. As with any network component, real‑world experiences depend on host device compatibility, firmware support in switches and NICs, and correct installation practices.
Practical buying considerations
Key procurement and deployment notes to consider before purchasing the XG‑SFP‑AOC3M:
- Compatibility:Confirm that your switches, servers or NICs accept third‑party AOCs. Some vendors restrict use to their own certified optics, so check vendor documentation or test first in a lab.
- Price and value:The product record lists a suggested price of 114.99 (currency unspecified) with a cost price noted as 96.44. Evaluate total cost versus alternatives like passive DACs or discrete transceivers when making a decision based on budget and lifecycle costs.
- Warranty and lifecycle:The product listing indicates no warranty details in the provided record. Ask your reseller or Ruijie representative about warranty terms and RMA processes before purchase.
- Documentation:For exact optical transmit/receive figures and regulatory compliance tables, consult the Ruijie RG 10GBASE Series datasheet to verify link budgets and environmental qualifications for your deployment.
