Moduletek SFP-25G-ER-I Optical Module sample performance evaluation

Time: 2024-01-03
        Moduletek newly launched model SFP-25G-ER-I-C10 optical module products, can support 25G Ethernet transmission 40KM in single mode fiber, Moduletek Limited laboratory testing of the product samples, to facilitate a further understanding of the product's performance indicators and the effect of the actual machine use.
1. Product Description
        Moduletek SFP-25G-ER-I-C10 Optical Module supports 40KM link length on 25G Standard Single Mode Fiber (SMF) G.652, and supports industrial temperature range (-40~85℃); the module requires FEC mode RS-FEC on the host port for full range operation under 25G. The official ordering information and module appearance are as follows:
