Finisar® Transceivers and Transponders for Datacom and Telecom Applications

II-VI's broad product selection and innovative technology have made us the optical module manufacturer of choice for all major networking equipment vendors worldwide. We have taken a leading role in transforming the datacommunications and telecommunications equipment market from utilizing discrete optical components to leveraging the design and pay-as-you-grow flexibility offered by pluggable modules. Our products are fully compliant with Ethernet, Fibre Channel, Infiniband, SONET/SDH/OTN, CPRI and PON standards and operate at data rates in excess of 100 Gb/s. They are capable of distances ranging from very short reach within a data center to campus, access, metro, and long-haul reaches. They feature outstanding performance over extended voltage and temperature ranges, while minimizing jitter, electromagnetic interference (EMI) and power dissipation.

Patented Digital Diagnostics

Finisar® Transceivers feature a microprocessor and diagnostics interface that provide performance information on the data link. Users can remotely monitor - in real-time - received optical power, transmitted optical power, laser bias current, transceiver input voltage and transceiver temperature of any transceiver in the network. These digital diagnostic functions provide network managers with a highly accurate, cost-effective tool for implementing reliable performance monitoring.
