- Partner
- Coretek
Compact Small Form-factor Pluggable (CSFP) transceivers are in fact two bi-directional transceivers housed in the industry standard SFP transceiver mechanical package. Coretek’s CSFP and CSFP+ transceivers fully comply to the CSFP MSA for all electrical, mechanical, and addressing specifications.
The CSFP and CSFP transceivers are optimised for low power consumption whilst delivering maximum performance both optically and electronically.
Designed especially for telecom and datacom network systems where extreme high-density configurations are deployed, the CSFP form factor contributes to reducing networking costs without sacrificing performance.
