Cisco Optical transceiver Model Classification

The main classifications of Cisco optical modules are SFP, SFP +, SFP28, QSFP +, QSFP28. HTF professional optical module manufacturers list the common models of Cisco optical modules below.

100Base SFP Optical Transceivers

1000Base SFP Optical Modules

SFP+ optical module

SFP+ optical module is the smallest hot-pluggable 10G optical module  ( 10 Gigabit optical module ),  which is mainly used in the SFP + port of the switch,  and can Interactive use in the same link with 10GBASE XENPAK,  10GBASE X2,  and 10GBASE XFP optical modules.

25G SFP28 optical module

Cisco SFP-25G-SR-S,  25GBASE-SR SFP28 module for MMF,  supports 70 / 100m link length on OM3 / 4 MMF;
Cisco SFP-10 / 25G-CSR-S,  10 / 25GBASE-CSR SFP28 module for MMF,  supports 300 / 400m link length on 25G OM3 / OM4;
Cisco SFP-10 / 25G-LR-S,  10 / 25GBASE-LR SFP28 module for SMF,  supports 10km link length on both 10G and 25G.

40G QSFP + optical module
QSFP + is an optical module born to meet the market demand for higher-density,  high-speed pluggable solutions. This 4 channel pluggable interface has a transmission rate of 40Gbps.

100G QSFP28 optical module

QSFP28 optical module uses the most advanced 100G transmission technology to provide data center operators with the connection between the rack switch and the core network.
