👉 Optical modules rely on a multi-chip cooperative system, including DSP, Driver IC, TIA, PD/APD, laser sources, and control/memory chips, working together to achieve high-speed electrical-to-optical signal conversion and transmission. The Transmitter Optical Sub Assembly (TOSA) is responsible for the emission of light. Its primary function entails converting electrical signals into optical signals. This assembly comprises a light source, such as a laser diode or a semiconductor light-emitting diode (LED), an optical interface, a. DSP (Digital Signal Processing) refers to the use of digital computation to manipulate signals such as audio, video, or sensor data. It involves transforming real-world analog signals into digital form, processing them using mathematical algorithms, and converting the processed signals back to. The Marvell coherent DSP portfolio, including Orion™, Canopus™ and Deneb™ platforms, empower the optical module ecosystem with low-power, high-performance silicon for QSFP-DD, OSFP and CFP2-DCO coherent pluggable form factors for AI cloud data center interconnect and 5G telecom and long-haul. Credo's high‑performance, energy‑efficient PAM4 optical DSPs are designed for the demands of hyperscale data centers and AI compute fabrics. Among various optical module form factors, SFP (Small Form-Factor Pluggable).
