1. SFP28 Knowledge Extension


SFP28 Cage is one - piece metal cage for EMI protection, combined with SFP28 female connector, then mount the SFP28 cage connector onto the PCB by Press Fit;

Users just need to connect the SFP28 Optical Transceiver to the SFP28 Cage connector, then we can do fast, long distance and efficient signal transmission;


SFP28 optical transceivers are designed for use in 25/28G Gb/s data rate over multimode or single model fiber. They are compliant to IEEE 802.3by, SFF-8472 Rev 12.2 and SFF-8402, and compatible with SFF-8432 and applicable portions of SFF-8431 Rev. 4.1. The optical transceiver is compliant per the RoHS Directive 2011/65/EU.

SFP28 is a 25GBASE interface which has evolved from 100 Gigabit Ethernet, which is typically implemented with 4 × 25 Gbit/s data lanes. Identical in mechanical dimensions to SFP and SFP+, SFP28 implements one 28 Gbit/s lane for top-of-rack switch to server connectivity.SFP28 may also be used to "break out" a single 100GbE port in a top-of-rack switch into four 25 Gbit/s individual server connections. SFP28 functions with both optical and copper interconnects.



2. Who is GLGNET?



GLGNET is the manufacture who develop and produce many different SFP Cages, with or without Integrated Female Connector;



The GLGNET SFP28 Cage is Compatible with small form-factor family of optical transceivers and cables. GLGNET provides a cost-effective SFP28 cages for EMI protection, Users want to achieve instant fiber connectivity and connect the network to different fiber distances and types at rapid data rates, like 25G ( SFP28 ) 40G ( QSFP+ ) and 100G ( QSFP28 ), they need SFP Optical Module (Transceiver ), Fiber cables, Female Connectors and SFP Cages which is for EMI Protection;
