V23839-R35-L55 Datasheet, PDF (6/34 Pages) Infineon Technologies AG – iSFF - Intelligent Small Form Factor 1.25 Gigabit Ethernet 4.25/2.125/1.0625 Gbit/s Fibre Channel Multimode 850 nm Transceiver with LC™ Connector

V23839-R3x-L55
Description
The Infineon iSFF multimode transceiver is a single unit comprised of a transmitter, a
receiver, and an LC™ receptacle.
This transceiver supports the LC™ connectorization concept. It is compatible with RJ-45
style backpanels for high end datacom and telecom applications while providing the
advantages of fiber optic technology.
The module is designed for low cost SAN, LAN, Fibre Channel and Gigabit Ethernet
applications. It can be used as the network end device interface in mainframes,
workstations, servers, and storage devices, and in a broad range of network devices
such as bridges, routers, hubs, and local and wide area switches.
This transceiver operates at 1.0625 Gbit/s / 1.25 Gbit/s / 2.125 Gbit/s / 4.25 Gbit/s from
a single power supply (+3.3 V). The 100 Ω differential data inputs and outputs are
CML compatible.
