Optic.ca NGS25G-LR-OC — 25G SFP28 long-range optical transceiver, NETGEAR certified
The Optic.ca NGS25G-LR-OC is a 100% NETGEAR-certified 25GBASE-LR SFP28 optical transceiver designed for high-speed, long-distance data transmission in enterprise and data centre networks. It delivers 25 Gbps over single-mode duplex fiber with a reach of up to 10 km, making it well suited for inter-building links, data centre interconnects, and high-performance computing backbones. Fully compliant with IEEE 802.3by and IEEE 802.3cc standards and featuring built-in Digital Diagnostic Monitoring (DDM), it is engineered by Technologie Optic.ca Inc.—a Canadian specialist exclusively focused on optical connectivity—and is pre-tested before shipment against NETGEAR's own M4350 and M4500 switch certification programme.
Certified NETGEAR Compatibility, Zero Guesswork
The NGS25G-LR-OC carries full NETGEAR® certification, meaning it has been validated and listed by NETGEAR for use in their M4350 and M4500 switch families. Unlike generic third-party modules that require manual CLI overrides or risk being blocked by switch firmware, this transceiver is recognised natively—it simply inserts and operates. For network operators, this translates directly into a faster, cleaner deployment: no unsupported-module warnings, no firmware workarounds, and no ambiguity during a support call. The module coding is performed in-house by Optic.ca's R&D team, ensuring each unit is aligned to NETGEAR's exact OEM specification.
10 km Reach on Standard G.652 Single-Mode Fiber
Operating at 1310 nm with a transmit power range of -5 dBm to +2 dBm and a receive sensitivity of -11 dBm, the NGS25G-LR-OC comfortably covers the 10 km LR distance budget on industry-standard G.652 single-mode fiber—the most widely deployed SMF type globally. This makes it ideal for campus backbones, inter-building 25G uplinks, or connections between co-located data halls that share existing dark-fiber infrastructure. No special fiber preparation or amplification is needed within the 10 km envelope, keeping deployment simple and cost-efficient.
Built-in DDM for Proactive Link Health Monitoring
Digital Diagnostic Monitoring (DDM) exposes real-time optical parameters—TX power, RX power, temperature, supply voltage, and laser bias current—directly to the host switch's management interface. This allows network operations teams to detect degrading fiber, dirty connectors, or a failing laser before a link drops, shifting maintenance from reactive to predictive. In practice, a technician can confirm a clean insertion loss reading immediately after installation, and the NOC can set threshold alerts that catch deterioration weeks before it causes an outage—particularly valuable on long-distance inter-site links where physical inspection is costly.
Lifetime Warranty and Tier 1 Component Quality
Every NGS25G-LR-OC is manufactured with Tier 1 MTBF-grade components and individually pre-tested before shipment. Optic.ca backs the transceiver side with a lifetime warranty, meaning the asset is covered for the full operational life of the network equipment it serves. For budget-conscious network builds where per-port optic costs add up quickly across a 25G spine, this removes the residual risk normally associated with third-party optics and eliminates the need to provision a spares budget for transceiver failures.
