The WDM or BIDI small form-factor pluggable (SFP) is a compact optical transceiver, module used in optical communications for both telecommunication and data bidirectional communications applications.

Eoptolink manufactures RG45 1000BASE-T , 100BASE-T or 10/100/1000BASE-T Auto-negotiation SFP transceivers.

The CWDM SFP small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications on 18 CWDM waves. Eoptolink is also producing BIDI CWDM SFP.

The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications.
