40G and 100G CFP Transceivers

OptoSpan CFP (C Form-Factor Pluggable) transceivers were developed to support the transmission of very high-speed digital signals, providing a bandwidth of 40G or 100G, with distances reaching up to 40 kilometers. CFP Transceiver modules are hot-swappable. Available for use with standard Duplex transmissions.


QSFP+ Transceivers

OptoSpan premium QSFP+ (Quad Small Form-Factor Pluggable) transceiver modules are designed or high-density fiber optic network applications, providing four channels of data into one pluggable interface. QSFP+ transceivers provide data rates of up to 40G and span distances of up to 10 kilometers, intended for use with short reach standard duplex equipment.


CFP Converter Transceiver

OptoSpan’s CFP-40G-SPPCONV advanced CFP to SFP+ Converter is designed to convert CFP interface to 4 channel SFP+ Modules.
