​56Gb/s QSFP+ SR4
Transceiver

Crowntech’s innovative technology have made us the optical module manufacturer of choice for many networking equipment vendors around the world used in transforming the data communications and telecommunications equipment market.

 

Crowntech offers transceivers operating at data rates over 100 Gbps which are fully compliant with Ethernet, Fibre Channel, Infiniband, SONET/SDH/OTN, CPRI, OIF, and PON standards. These modules range from very short reach within a datacenter to campus, access, metro, and long-haul reaches, by utilizing a broad portfolio of high-end optical components (e.g. 850 nm VCSELs, DFB lasers, EML lasers, wavelength-tunable lasers, and coherent photonic integrated circuits). Crowntech’s products also feature outstanding performance over extended voltage and temperature ranges while minimizing jitter, electromagnetic interference (EMI), and power dissipation.
