LINK-PP LS-MM8525-S3C provides 25Gbps Ethernet over 850nm multi-mode fibre, with reach extending to 300m on OM3. It also incorporates a digital diagnostic interface and an MCU for parameter logging, making it a practical choice for leaf-spine aggregation and top-of-rack interconnections.
This transceiver is built with three main components: an 850nm VCSEL laser transmitter, a PIN photodiode with an integrated TIA, and an MCU control unit. These components work together to ensure accurate signal transmission and reception. The design supports reliable optical performance and stable operation.
It enables 25Gbps data links commonly used in leaf-spine network architectures. The module supports fast and efficient data exchange between switches. It is suitable for short-distance high-density network connections.
The module operates at 850nm, a wavelength optimised for multi-mode fibre transmission using VCSEL sources. This wavelength ensures low modal dispersion and efficient coupling into OM3 fibre types. It is the standard choice for 25G short-range optical links.
It supports transmission distances of up to 300m over OM3 multimode fiber, making it well suited for short-reach links in data center and enterprise network environments. It provides a reliable option for typical switch-to-switch or server connectivity where stable performance and efficient cabling are important.
The module uses a Duplex LC/UPC optical interface for reliable fiber connectivity. This interface allows simple installation and stable signal transmission. It is widely adopted in SFP28 optical modules.
Built-in DOM allows real-time tracking of key operating parameters such as optical output power, received power, laser bias current, and module temperature. The MCU continuously updates these values via the I²C interface, enabling the host system to monitor link health and predict potential failures.
LINK-PP LS-MM8525-S3C meets key industry standards and is certified with ISO 9001, CE, RoHS, and FCC to ensure product quality and compliance.
The module undergoes a comprehensive testing program that includes optical parameter validation and bit-error-rate verification.
It holds multiple quality certifications that attest to its manufacturing process consistency and product reliability.
The module has been certified for compatibility with a wide range of host devices, ensuring stable 25G Ethernet connections without interoperability issues.
Comprehensive validation checks confirm stable transmission and consistent optical behavior across operating conditions. For additional details, visit the LINK-PP Test Support Center.

Q: Is this optical module suitable for short-reach inter-rack patching between indoor storage arrays and ToR switches? By H***e on 2026-03-30
A: Yes, its short-reach 850nm VCSEL transmitter is specifically optimized for high-speed intra-rack and inter-rack MMF interconnects. By admin on 2026-03-31
Q: Does the metal housing on the LS-MM8525-S3C module cause electrical noise or signal crosstalk in tightly packed server racks? By M***t on 2025-12-16
A: No, the module features an all-metal enclosure specifically engineered to deliver low Electromagnetic Interference (EMI) across adjacent ports. By admin on 2025-12-17
Q: Will these transceivers work reliably in fully populated 48-port high-density switch setups without overheating adjacent ports? By V***a on 2025-08-27
A: Absolutely, each module consumes less than 1.0W from a single 3.3V supply, keeping thermal output low even in high-density switch chassis. By admin on 2025-08-28
Q: Does the dual-channel internal CDR on this module help reduce signal jitter on high-speed 25.78Gbps links? By J***t on 2025-04-14
A: Yes, the built-in Clock and Data Recovery (CDR) on both transmitter and receiver channels cleans up electrical jitter for maximum signal integrity. By admin on 2025-04-15
