These modules convert physical signals from electrical to optical (and vice-versa) in a network and couple the optical signals into (and out of) optical fiber. For 40 Gb/s applications, SONET OC-768, SDH STM-256 and DWDM tunable versions are avail-able. 300-PIN modules are used primarily in teleco optical links. The electrical interface to the host board i c transceivers. It is protocol-independent and fully compliant to the following. Use the catalog tabs to review optical transceiver modules, SFP module families, DWDM system options, CWDM module selections, GPON OLT access equipment, and PLC splitter categories supplied through the backend product catalog. Request module compatibility, insertion-loss allowance, EEPROM notes, or. Finisar (now part of II-VI, but everyone still calls them Finisar) has one of the widest portfolios of optical modules. I don't have the exact count, but in my experience, they cover more standards and data rates than most other single vendors. Users can remotely monitor—in real-time—received optical power, transmitted optical power, laser bias current, transceiver input voltage and transceiver temperature of. Our Finisar® transceivers feature a microprocessor and diagnostics interface that provide performance information on the data link. Finisar has taken a leading role in transforming the data communications and telecommunications equipment markets from utilizing expensive discrete optical components to high-volume pluggable pay-as-you-grow haul net-works.
