coherent optical module
The Gigalight 100G CFP-DCO digital coherent optical transceiver is a hot-pluggable CFP form-factor optical module designed for high-speed optical networking applications including 100-Gigabit Ethernet and OTU4. The CAUI and OTL4.10 electrical interface and MDIO management interface are built in the module. The 100G CFP-DCO module converts 10-lane 10Gb/s electrical data streams to 128G DP-QPSK optical output signal in Egress, and also converts DP-QPSK optical input signals to 10-lane 10Gb/s electrical data streams in ingress. This 10-lane 10Gb/s electrical signal is fully compliant with 802.3ba CAUI specification and OIF-CEI-03.1 specification, and allows FR4 host PCB trace up to 25cm.
The Status of Silicon Photonics Technology in the Application of Optical Module With the maturity of waveguide theory and the production of a series of new design devices, the industry has proposed Silicon Photonics technology based on CMOS manufacturing processes. Silicon Photonics utilizes the very mature silicon wafer processing technology of the traditional semiconductor industry. It can process large-scale waveguide devices on the silicon substrate by etching process. By using processes such as epitaxial growth, it is possible to prepare key devices such as modulators and receivers, and finally achieve high integration of modulators, receivers, and passive optical devices. In addition to the laser, the Silicon Photonics technology can realize the integrated manufacturing of various devices in the optical module, covering most components inside the optical module, but does not include the laser chip. Since silicon is an indirect band gap, the conduction band minimum (conducting band bottom) and the full band maximum are in different positions in k space. The electronic transition needs to change the potential energy and kinetic energy at the same time. The laser needs to…
