The UltraLAN 25G SFP28 transceiver is a high-performance, cost-effective optical module designed for short-range, high-speed links in data centres, enterprise networks, and high-bandwidth environments.
Operating at 850nm with a VCSEL laser, it supports transmission distances of up to 70m on OM3 fiber and 100m on OM4 fiber.
Compliant with SFP28 MSA, SFF-8402, and SFF-847 standards, it ensures compatibility across networking equipment.
With Digital Diagnostic Monitoring (DDM), users gain real-time visibility into operating parameters for improved reliability and management.
Compact, hot-pluggable, and energy-efficient (<1W), it’s built for stable operation in commercial temperature ranges, backed by a 24-month warranty.
