Engineered to support high-density routing and core switching nodes in demanding local environments.
The Central African Republic (CAR), particularly centered around the digital nodes of Bangui, is entering a vital phase of telecommunications expansion. Initiated by the regional Central African Backbone (CAB) project and funded by international organizations like the African Development Bank, the nation is aggressively scaling up its fiber optic infrastructure. High-speed interconnections require robust component architectures at the hardware level, where 2xN stacked port cages play an indispensable role.
Stacked 2xN layouts (including 2x1, 2x2, 2x4, 2x6, and 2x8 port densities) allow network design engineers to double the input/output (I/O) capability on a fixed PCB layout. For Central African telecoms and IT service providers, this reduces the total deployment footprint in data hubs, optimizing high-bandwidth connectivity and drastically lowering capital expenditures (CAPEX) for thermal housing and physical server expansion.
Information Gain Indicator: Deploying optical network infrastructure in Central Africa exposes hardware to extreme environments, including dust ingress from the Sahel winds (Harmattan) and sustained high temperatures. Our 2xN cages leverage advanced EMI elastomer gaskets and rugged thermal management routes to prevent optical signal degradation.
To survive local power stability variations and minimize insertion losses, modern 2xN SFP/SFP+/SFP28 design must emphasize high mechanical durability. Key architectural advantages include:
The standard SFP, SFP+, and SFP28 specifications require precise adherence to multi-source agreements (MSAs). However, the implementation of a stacked (2xN) architecture introduces significant electromagnetic interference (EMI) and thermal dissipation challenges. In a stacked configuration, the top and bottom ports sit directly on top of each other, sharing a middle metal divider. If the design is not optimized, cross-talk between the vertically stacked channels can severely affect the Bit Error Rate (BER).
At 10Gbps (SFP+) and 25Gbps (SFP28) speeds, even minor variations in differential impedance can create significant signal reflections. Our manufacturing process uses automated assembly with high-precision stamped terminals. The design maintains 100-ohm differential impedance across all high-speed paths. By optimizing the pin design at the press-fit transition zone, we reduce signal return loss, which is essential for long-haul optical transmissions across Central Africa's developing fiber networks.
Central African Republic's network infrastructure demands equipment that can withstand high relative humidity and dust storms. Dust accumulation inside optical transceiver ports can lead to hardware failures. To address this, our 2xN cages are compatible with specialized elastomeric gaskets that seal the card interface and prevent dust from reaching the contact pins. Furthermore, we use nickel-plated copper alloy base metals with selective gold plating on contacts, protecting components from corrosion caused by moisture.
Bridging the gap between international hardware manufacturing capabilities and local African network deployments.
Double the port count per rack unit (RU). Enable transitions from legacy 10G SFP+ to 25G SFP28 systems without redesigning existing system footprints, saving valuable space in metropolitan centers.
Integrated thermal venting structures within the 2xN middle wall support increased airflow. This helps keep active optical modules cool in environments without constant air conditioning.

Answers to critical design and supply questions regarding SFP/SFP+ 2xN stacked systems.
Press-fit terminals establish a gas-tight, solder-free connection using elastic deformation inside the PCB plated through-holes. This eliminates issues with cold solder joints and thermal stress during manufacturing. It also makes replacement easier in remote telecom sites like those in the Central African Republic, where rework stations may not be available.
We offer two main configurations: spring-fingers and elastomeric conductive gaskets. Gaskets provide superior EMI containment at frequencies above 10 GHz by establishing continuous contact between the module and the cage opening. This prevents radiation leaks that could impact adjacent high-speed circuits on the PCB.
Shipments to CAR are typically routed through Douala Port (Cameroon) and transported by road to Bangui, or shipped via air freight to Bangui M'Poko International Airport. Standard production lead time is 2-4 weeks, depending on order size. We manage all transit packaging to protect components from dust and moisture during transport.
Yes. All our SFP, SFP+, and SFP28 cages are built strictly in accordance with SFF-8432 and SFF-8402 Multi-Source Agreements (MSAs). This ensures total compatibility with transceivers from Cisco, Finisar, Juniper, and other major brands.
