Key Features of Mellanox SFP28-25G-BX Compatible LINK-PP 25G SFP28
Mellanox SFP28-25G-BX Compatible LINK-PP streamlines modern data networks by combining high-speed capabilities with a highly efficient single-fiber design. This optical transceiver helps operators scale their bandwidth capacity over long distances while keeping infrastructure overhead low. By consolidating advanced signaling and diagnostics into a compact footprint, it serves as a reliable building block for modern telecom frameworks.
This module features a hot-pluggable electrical interface, allowing network administrators to plug it directly into live ports for effortless upgrades or quick replacements. It is engineered for low power consumption, which keeps running costs down and reduces the overall thermal load inside crowded network switches. These traits make it incredibly easy to manage in high-density rack deployments.
SFP28-25G-BX: 25 Gbps Connectivity for High-Speed Fiber Links
Delivering a massive 25 Gbps data rate, this optic easily satisfies the heavy traffic demands of cloud systems and mobile networks. It provides the necessary speed boost to clear out network congestion and keep data flowing smoothly without delays. Transitioning to this throughput level allows enterprise systems to handle next-generation applications effortlessly.
SFP28-25G-BX Module with 1270nm-TX/1330nm-RX Wavelength
Operating through a 1270nm-TX and 1330nm-RX configuration, the transceiver splits traffic into separate spectral lanes on the very same strand of glass. This specific optical separation ensures that oncoming data streams pass each other seamlessly without causing errors or crosstalk. It provides a clever way to double the traffic capacity of your existing fiber layout.
SFP28-25G-BX Module Supporting 10km Transmission
With a maximum reach of 10km on standard 9/125µm single-mode fiber (SMF), this optic bridges the physical gap between regional distribution hubs. The internal laser maintains strong, clean signals over miles of fiber, making it perfect for base stations and campus backbones. It reliably connects distant facilities without requiring intermediate signal boosters.
SFP28-25G-BX Module with Simplex LC/UPC Interface
Utilizing a simplex LC/UPC connector plug, the unit relies on just one fiber line instead of the usual two-strand duplex setup. This instantly frees up half of your physical patch panels and reduces the amount of fiber bulk you need to purchase and route. It is an excellent choice for expanding network capacity when physical cable space is tightly limited.
SFP28-25G-BX Module with DOM for Real-Time Monitoring
Equipped with Digital Optical Monitoring (DOM), this unit constantly tracks its own internal telemetry, including laser power, voltage, and temperature. Technicians can view these live health metrics straight from the switch console to catch optical degradation early. This built-in visibility makes troubleshooting fast and prevents sudden network outages.
Every optical unit passes through comprehensive signal integrity and environmental stress trials to guarantee flawless operation under heavy network loads.

As a principal infrastructure engineer managing a metro-scale enterprise campus network backbone, transceiver reliability is non-negotiable for our operations. We thoroughly benchmarked the LINK-PP LS-BL273325-10C 25G SFP28 BiDi against several higher-priced alternatives. Operating over an 8.7km single-mode fiber (SMF) link, this 1270nm-TX/1330nm-RX transceiver demonstrated stellar performance parameters. Our optical link budget calculation estimated an insertion loss of roughly 3.2dB across the link, including three patch panels, and the receiver sensitivity stayed well below the -13dBm threshold with ample headroom. Digital Diagnostics Monitoring (DDM) telemetry was queried via SNMP into our Prometheus/Grafana stack, showing highly stable laser temperature profiles and laser bias currents that track linearly with traffic volume. For anyone looking to achieve single fiber savings while scaling their access layer to true 25GBASE-U speeds, these modules deliver excellent signal integrit

We deployed a batch of these LS-BL273325-10C 25G SFP28 optics for our university campus network expansion. Moving from 10G to 25G SFP28 BiDi was seamless since we didn't have to lease additional dark fiber. The simplex LC setup works exactly as advertised, keeping insertion loss well under our strict budget. Will buy bulk next quarter.

Tested these 10km BiDi SFP28 modules across a legacy fiber plant with multiple patch panels, and the insertion loss remained well within budget limits. The modules run cool and pull less than 1.5W per port. Shipping took one extra day to clear our local regional customs hub, which cut it close for our deployment window. Will definitely order again, just with a larger time buffer next time! ✈️

From a procurement and network operations perspective, finding a high-reliability supplier for optical components that fully comply with standard SFF-8472 digital optical monitoring interfaces can be tricky. We shifted our bulk procurement for mid-mile telecom aggregation to LINK-PP, and this LS-BL273325-10C 25G BiDi module proves why they are a trusted name. We deployed these across a 9.5km corporate campus network backbone link. Leveraging standard single-mode fiber patch cables, the simplex LC/UPC connector provided a perfect physical mate with zero axial misalignment. The DFB laser transmitter handles signaling mode cleanly, maintaining a tight spectral width that effectively eliminates any risk of chromatic dispersion over the 10km rated distance. Our monitoring tools track real-time DOM metrics, showing an operating temperature well within the standard 0°C to 70°C commercial range even during summer peak loads in unconditioned distribution frames. These are a solid investment for

Deployed a set of these LS-BL273325-10C optics to handle a critical high-speed link between our corporate headquarters and our secondary disaster recovery site located 8.2km away. The existing link was congested at 10G, and upgrading to 25G SFP28 BiDi allowed us to triple our synchronization throughput without changing a single inch of our single-mode fiber infrastructure. The simplex LC setup works perfectly. We paired this unit with the complementary 1330nm-TX/1270nm-RX optic on the remote side. Both ends established a stable link instantly on our switches. No framing errors, zero packet retransmissions, and a perfectly flat latency profile during full-capacity disaster recovery simulation testing. The Digital Diagnostics Monitoring interface provides instantaneous updates on transceiver metrics, giving us peace of mind for mission-critical storage replication. LINK-PP has delivered a highly reliable, plug-and-play solution that saved our infrastructure costs.

The 25G SFP28 BiDi links came up instantly on our Arista switches, and the DOM readings are spot on. However, the package courier left the bulk box on our loading dock in the rain instead of bringing it inside. Fortunately, LINK-PP's internal anti-static bags sealed the optics perfectly from moisture, but local delivery tracking could be better handled.

Our engineering team recently completed a large-scale data center migration project involving over two hundred 25G Ethernet server-to-switch interconnects. We chose the LS-BL273325-10C SFP28 modules for our high-density aggregation frames. A major technical hurdle with generic 25G optics is often clock and data recovery (CDR) unlock or signal integrity degradation when operating at peak 25.78Gbps line rates under full load. After a rigorous 72-hour burn-in phase using pseudorandom binary sequence (PRBS31) test patterns, these transceivers maintained zero pre-FEC and post-FEC bit errors. The physical build quality is robust; the zinc alloy housing provides superb EMI shielding, and the simplex LC/UPC optical interface ensures a secure mechanical fit that prevents physical drift or micro-disconnections. Furthermore, the real-time DOM telemetry features allowed us to map exact optical power values directly from our switch CLI. Outstanding engineering work by LINK-PP optical module!
