Transmitter Optical Sub-Assembly (TOSA)

MACOM's transmitter optical sub-assemblies (TOSA) are focused on enabling our customers high performance/high bit rate optical transceivers operating at 100G and beyond. Our current 100G TOSAs are high performance and low power consumption 4 x 25G 1310nm LAN-WDM TOSA, consisting of an Optical Multiplexer to combine 4 wavelength light signals, highly-reliable MACOM cooled Direct Modulated Lasers (DMLs) and MACOM quad laser driver or 4x25G/28G 1310nm LAN-WDM TOSA, consisting of an Optical Multiplier to combine 4 wavelength light signals and highly-reliable cooled Electroabsorption Modulated Lasers (EMLs). The TOSA is assembled in a hermetic-sealed package with an LC receptacle for optical output and two flex circuits for DC/RF electrical connections. The TOSA is best suitable for CFP, CFP2, CFP4 and QSFP28 applications.
