25G SFP28 multimode fiber optic module with 850nm VCSEL for 25GBASE-SR Ethernet applications.
When high-bandwidth interconnects are required for 25G Ethernet or CPRI wireless networks, signal integrity over multimode fiber is critical. The LRTP8525-X1ATL fiber optic module addresses this need with precise optical performance.
This 25G SFP28 transceiver supports bidirectional data links from 21Gb/s to 25.83Gb/s, enabling seamless 25GBASE-SR compliance. With an 850nm VCSEL transmitter, it achieves transmission distances up to 100m on OM4 fiber and 70m on OM3, eliminating short-reach connectivity gaps in data center racks.
Designed for enterprise and telecom deployments, this hot-pluggable module integrates digital diagnostics via a 2-wire serial bus for real-time monitoring. It provides a cost-effective, RoHS-compliant optical interface solution for upgrading existing 25G infrastructure without replacing cabling.
Supports bidirectional data links from 21Gb/s to 25.83Gb/s for 25GBASE-SR Ethernet applications.
Utilizes 850nm VCSEL laser transmitter optimized for multimode fiber connectivity.
Achieves transmission distances up to 100m on OM4 and 70m on OM3 multimode fiber.
Implements SFF-8472 standard digital diagnostic functions through a 2-wire serial bus.
Allows installation and removal without powering down the host system for easy maintenance.
