Xelivor
High-density SFP/SFP+ copper cage assemblies designed to meet rigorous thermal, grounding, and EMI mitigation demands in high-altitude environments.
How advanced physical layer infrastructure accelerates telecommunications development and industrial automation in the Mountain Kingdom.
Lesotho's strategic focus on the National Broadband Policy and e-Government Infrastructure projects demands a robust physical optical transport layer. Transitioning municipal architectures in Maseru, Leribe, and Mafeteng to gigabit and multi-gigabit capabilities requires high-density switches and routers. This transition is highly reliant on ganged cage solutions to optimize port layout density while protecting delicate silicon switches from signal degradation.
Deploying 1xN ganged ports allows local network operations to maximize faceplate density on localized optical terminals. By utilizing Xelivor's robust SFP cages, local providers prevent structural port collapse and electrical mismatches common in mountainous, fluctuating dry-climate environments.
Lesotho's premier mining sector, including the prominent Letšeng and Kao diamond mines, operates under extreme environmental stresses. Situated at elevations exceeding 3,000 meters above sea level, mining telecommunication relays face low atmospheric density. Standard cooling systems suffer from diminished convective heat dissipation in thin air, posing a significant risk of optical module failure.
Xelivor's integrated thermal heat sink solutions paired with 1xN ganged ports are designed specifically to overcome these thermal challenges. By integrating custom-engineered copper heat sinks directly onto the metal cages, we ensure optimal heat dissipation paths, keeping internal transceivers within safe thermal envelopes.
Lesotho relies on cross-border optical fibers traversing South Africa to reach international submarine landing stations (such as Mtunzini and Melkbosstrand). The edge switches deployed at border gate routing installations (Maseru Bridge, Maputsoe) act as high-capacity aggregation hubs. Implementing EMI-shielded 1x6 and 1x8 ganged SFP+ cages ensures that adjacent channel signal noise is suppressed, maintaining error-free packet transmissions over thousands of kilometers of regional transit backhaul.
Detailed architecture showcasing EMI mitigation, physical retention, and long-term signal integrity.
High-speed data lanes operating at 10Gbps to 28Gbps generate high-frequency electromagnetic interference. Our cages utilize specialized elastomeric or metal spring-finger gaskets at the bezel interface to prevent EMI radiation leakage, complying with strict FCC and CE limits.
Eliminating the thermal stresses of hand soldering, press-fit (compliant pin) terminations provide reliable electrical and mechanical contact with the PCB. Our press-fit pins are designed with precision tolerances to avoid damaging multi-layer board vias during installation.
Integrated optical light pipes route visual status indicators from the PCB surface to the front bezel. Available in various profiles (standard, low-profile, round, or square) to accommodate different faceplate layouts.

Targeted designs supporting localized rural telecom centers, power distribution systems, and legacy infrastructure upgrades.
Aligning custom design options with the specific operational demands of regional network infrastructure.
For central offices and optical line terminals (OLT) deployed in Maseru and Leribe, maximizing the density of physical GPON ports is paramount. We recommend using 1x6 or 1x8 SFP+ ganged assemblies with riding heat sinks. This ensures that when transceiver modules run at full capacity, heat is conducted away instantly, avoiding packet drop and optical degradation.
Rugged operations like those in Letšeng require hardware that can withstand dust ingress, continuous vibration, and extreme temperatures. Utilizing THT (Through-Hole Technology) Solder Cages provides a superior mechanical bond to the PCB compared to standard surface-mount options, ensuring connectivity is maintained even under heavy physical vibration.
