Our 25G SFP transceiver series provides a critical performance upgrade for modern data centers, delivering a 2.5x increase in bandwidth over traditional 10G SFP+ solutions within the same compact form factor. This series is engineered to address the specific bandwidth demands of server-to-switch connections, storage area networks, and high-performance computing clusters. It offers two tailored solutions: the 25G SFP 850nm 100m for high-density, cost-effective short-reach links, and the 25G SFP 1310nm 10km for reliable, extended-reach connectivity.

Product 1: 25G SFP28 850nm 100m (SR)
This module (MCS-4NV18C-1H) is designed for ultra-short-reach, high-density interconnects within a data hall. Utilizing an 850nm VCSEL transmitter and a PIN photodiode receiver, it supports links up to 70 meters on OM3 and 100 meters on OM4 multimode fiber. It is the ideal, power-efficient choice for top-of-rack (ToR) switch connections to servers or for spine-leaf architectures within a single rack or adjacent racks. Operating on a 3.3V supply within a 0°C to 70°C range, it complies with SFP28 MSA, SFF-8431, and SFF-8432 standards, ensuring broad interoperability.

Product 2: 25G SFP28 1310nm 10km (LR)
Built for medium-distance applications, this module establishes robust 25G links up to 10 kilometers over standard single-mode fiber via a duplex LC connector. It employs a high-quality 1310nm transmitter and a high-sensitivity PIN-TIA receiver to ensure signal integrity over extended distances. With a typical power consumption of less than 1.2W and compliance with SFF-8472 for digital diagnostics, it is perfectly suited for campus network backbones, data center interconnects (DCI), and metro access applications, offering a reliable and scalable path for network expansion.

FAQ

Q: Does operating over the full 10km distance impact the performance or latency of the 1310nm module?

A: The data rate and bandwidth remain a consistent 25Gbps regardless of distance within the 10km limit. Signal latency increases slightly over fiber compared to a very short link (due to the speed of light in glass), but this increase is minimal (fractions of a millisecond) and negligible for almost all applications.

Q: Is 25G technology considered stable and well-supported for the long term?

A: Yes. 25G is an established and mature standard with broad adoption by all major switch, server, and NIC manufacturers. This ensures a robust ecosystem, competitive pricing, and long-term availability, making it a safe and future-proof investment for your network infrastructure.
