Multi Form Pluggable (MFP) 8-channel optical link modules for OC-3 (STM-1) and OC-12 (STM-4) intermediate reach (IR-a) applications have been developed. The MFP module can increase packaging density by 60% and reduce power consumption by 60% for virtually the same cost compared to the use of conventional single-channel 8 Small Form Pluggable (SFP) modules.

A high, density packaged 4-channel optical transceiver using a 1310 nm FP-LD array and a PD array has been newly developed for OC-3, OC-12, Gig-E and fiber channel intermediate reach applications. The output optical power of each of the four LDs is independently controlled by automatic power control (APC). Both module package size and power consumption can be reduced by less than half when compared to the use of four conventional single-channel small form factor pluggable (SFP) modules
