MSA and RoHS
Datasheet
The Intel
®
LC Small Form Factor Pluggable (SFP) optical transceivers are high performance
integrated modules for bi-directional communication over multi-mode optical fiber.
The Intel
®
TXN31115 Quad-rate 850 nm SFP Optical Transceiver (hereafter referred to as the
TXN31115 Optical Transceiver) is specifically designed for high-speed Fibre Channel data links
at 4.25 Gbps (4x Fibre Channel rate). The TXN31115 Optical Transceiver is also backwards
compatible with 2x and 1x Fibre Channel and Gigabit Ethernet rates. The TXN31115 Optical
Transceiver is provided with an LC receptacle that is compatible with the industry standard LC
connector.
The TXN31115 Optical Transceiver is Class 1 laser safety compliant with FDA Radiation
Performance Standards, 21 CFR 1040.10, and international standards IEC 60825-1 and IEC
60825-2.
