Lumetra
Optimized for major metropolitan interconnection hubs, including Toronto Digital Realty YYZ, Montreal OVHcloud hubs, and Vancouver Carrier Gateways.
Canada is executing a rapid digitization shift, driven by hyperscale expansion in Quebec (Montreal, Saint-Hubert, Beauharnois) and high-density colocation growth in Ontario (Toronto Downtown & Markham core), alongside Western Canada edge hubs (Calgary & Vancouver gateway to APAC). For system integrators and tier-1 telecommunications carriers (such as Rogers, Bell, Telus), optimizing board space while maintaining reliable thermal management is the top challenge.
This is where 2xN (Stacked Ports) structures show their distinct value. By housing two rows of transceiver ports in a single PCB footprint (configurations such as 2x1, 2x2, 2x4, 2x6, and 2x8), network hardware designers can effectively double the port density per rack unit (RU). Lumetra’s line of press-fit stacked cages is engineered specifically to replace legacy single-row designs without sacrificing signal integrity or thermal compliance.
How Lumetra addresses high-frequency electrical loss, heat dissipation, and mechanical tolerance limits for next-generation network hardware.
By using an "Eye-of-the-Needle" press-fit compliant pin geometry, our 2xN SFP cages establish gas-tight electrical contact with the backplane. This design avoids the thermal stress of wave soldering and prevents signal stubs that lead to high-frequency reflection at 25Gb/s (SFP28) operations.
Stacked configurations trap heat in the lower row. Our custom 2xN solutions integrate riding heat sinks and dual light-pipe configurations that are built directly into the housing. This configuration permits optimal ventilation while maintaining clear, real-time LED status tracking on the front panel.
Electromagnetic interference (EMI) degrades transceiver performance at higher frequencies. Lumetra utilizes a multi-point spring finger contact system and elastomeric gaskets to cover the bezel-to-cage interface, delivering reliable attenuation across a wide range of frequencies.
Engineered to match major mechanical footprints, simplifying drop-in replacement and second-source validation processes.
Lumetra Optoelectronics Technologies Co., Ltd. has established a modern, highly automated production model that addresses volatile hardware demand. Operating from our 8,500㎡ facility, our automated optical transceiver assembly and cage manufacturing divisions achieve manufacturing precision that meets international quality standards.
By leveraging automated high-speed progressive metal stamping dies, high-precision injection insert molding machines, and automated co-planarity inspection systems, we ensure that every compliant pin on our 2xN stacked connectors matches standard mechanical footprint specifications. This automation lowers manufacturing waste, keeping prices competitive while scaling capacity for large-scale infrastructure deployments.
Our production process utilizes real-time Automated Optical Inspection (AOI) to measure press-fit pin layout and height. Before shipment, every production batch undergoes environmental stress screening and signal integrity checks to guarantee reliable long-term performance under demanding telecom environments.
Exporting interconnect products to Canada demands adherence to mechanical and environmental health regulations. Lumetra's products are engineered to comply with target regulatory standards, helping our partners mitigate operational risk.
Meets environmental limits for heavy metals and toxic fire retardants.
Internal plastic housings limit flame propagation in data center fires.
Optimized EMI spring fingers help components meet ISED Canada regulations.
Navigating cross-border procurement requires predictable delivery times. Lumetra coordinates with leading global logistics providers to offer air freight options directly to major Canadian airports (YVR, YYZ, YUL), typically completing transit in under 5 to 7 business days.
Our dedicated engineering group works directly with your hardware team to review schematics and design customized solutions. Whether you require specific light-pipe configurations, modified EMI spring contact points, or varied compliance pin lengths, our R&D engineering team offers custom support.
How procurement professionals balance system reliability, supply chain diversity, and total cost of ownership (TCO).
Today's hardware procurement officers face a balancing act. Sourcing proprietary components from single-brand suppliers exposes lines to long lead times, while generic alternatives risk quality variation that can lead to field failure and costly recalls. Lumetra's TE- and Molex-compatible SFP/SFP28 cages provide a robust, drop-in replacement alternative for production lines.
By integrating Lumetra's 2xN stacked solutions into the initial design phase, manufacturers gain a qualified second source that helps maintain production continuity during component shortages. Our ISO-certified production facilities deliver reliable mechanical fit and optical performance, helping to lower production risks.

Find answers to common technical, mechanical, and logistical questions about Lumetra's 2xN SFP/SFP28 cages.
Our cages are manufactured using high-conductivity nickel-silver and copper-alloy sheet metal, which provides inherent EMI shielding. The contact fingers are engineered to establish multiple contact points along the module and bezel surface, lowering electromagnetic radiation and minimizing susceptibility to nearby high-frequency sources.
Yes. Our stacked cages are engineered to match standard electrical and mechanical footprints. This design compatibility allows you to drop our components directly into layout configurations designed for TE (e.g., 2007562-8, 2180640-1, 2347721-8) or Molex alternatives without requiring PCB design changes.
Lumetra manages the export documentation process, classifying items under HS Code 8517.62. We arrange air freight shipping to hubs like Toronto (YYZ), Montreal (YUL), and Vancouver (YVR), coordinating with local customs brokers to ensure timely, compliant delivery.
For high-density configurations like 2x6 and 2x8 models, we offer built-in heat sinks (such as pin-fin or mechanical fin configurations) that ride on top of the cage. We also include ventilation openings and integrated light pipe paths that do not obstruct airflow, helping to keep both upper and lower rows within safe operating temperatures.
