4×25G EML LANWDM TOSA

The CET1A0CREX-L30 TOSA is a cooled, 4x28Gb/s, 1310nm transmit optical

sub-assembly, for 100G applications, consisting of four high reliability,

high performance EML ,internal an optical multiplexer to combine the

outputs from the four EML. These elements are packaged in a hermetic,

planar package with an LC receptacle. The electrical interface is through

two flex connects. The TOSA is intended for use in QSFP28 modules,

serving the 100GBASE-ER4&OTU4 application, per IEEE 802.3ba standard.
