Low cost IC-package for 2.5-10 GBit/s 1310 nm VCSEL with single mode coupling

For longer distances single mode coupled 1310 nm or 1550nm FP or DFB lasers are used. A couple of companies are working on the 1310 nm VCSEL to replace the FP and DFB lasers to reduce cost and gain performance. The main advantages of the 1310 nm VCSELs are lower chip cost, lower packaging cost, lower power consumption and a very low threshold current. The extremely short opto-mechanical design gives an excellent HF-performance for 2.5 Gbps up to 10 Gbps applications. The flexboard interconnection avoids mechanical overdeterminations.
