Overview

LR-LINK LRTP1325-10ATL offers customers multi rate of up to 25.78 Gigabit Ethernet connectivity options for 5G front haul , Ethernet applications. This document specifies the electrical, optical, and mechanical characteristics of the 25Gbps module.

The LRTP1325-10ATL supports 25G CPRI and Ethernet application , it is offered in a cost-effective SFP28

form factor and I2C interface. The module supports a link length up to 10km on standard single mode fiber

such as SMF-28.The module converts 25Gbps electrical data to DFB-based high-performance optical signals for

optical transmission. Reversely on the receiver side, the module converts 25Gbps optical signal to electrical

data with PINbased receiver and CDR IC chip.
