They are compliant with SFF-84311, IEEE 802.3-2012 10GBASE-SR/SW2 and 1000BASE-SX3 . Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF- 84724 . The FTLX8574D3BCV is a “limiting module”, i.e., it employs a limiting receiver. Host board designers using an EDC PHY IC should follow the IC manufacturer’s recommended settings for interoperability with an SFP+ limiting module. This product is for applications specifically designed for 10G SFP+ ports and 1G/10G SFP+ ports and not native 1G SFP ports. The optical transceiver is compliant per the RoHS Directive 2011/65/EU5. See Finisar Application Note AN-20386 for more details. Diagram of Host Board Connector Block Pin Numbers and Names Figure: Diagram of Host Board Connector Block Pin Numbers and Names Host-Module Interface Figure: Host-Module Interface Regulatory ComplianceFinisar transceivers are Class 1 Laser Products and comply with US FDA regulations.These products are certified by TÜV and CSA to meet the Class 1 eye safety requirements of EN (IEC) 60825 and the electrical safety requirements of EN (IEC) 60950. Copies of certificates are available at Finisar Corporation upon request. Digital Diagnostic FunctionsFinisar FTLX8574D3BCV SFP+ transceivers support the 2-wire serial communication protocol as defined in the SFF-8472. It is very closely related to the E2 PROM defined in the GBIC standard, with the same electrical specifications.The standard SFP+ serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information. Additionally, Finisar SFP+ transceivers provide a enhanced digital diagnostic monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm and warning flags, which alerts end-users when particular operating parameters are outside of a factory set normal range. SFF-8472 defines a 256-byte memory map in E2 PROM that is accessible over a 2-wire serial interface at the 8 bit address 1010000X (A0h). The digital diagnostic monitoring interface makes use of the 8 bit address 1010001X (A2h), so the originally defined serial ID memory map remains unchanged. The interface is identical to, and is thus fully backward compatible with both the GBIC Specification and the SFP Multi Source Agreement. The complete interface is described in Finisar Application Note AN-2030: “Digital Diagnostics Monitoring Interface for SFP Optical Transceivers”. The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller (DDTC) inside the transceiver, which is accessed through a 2-wire serial interface. When the serial protocol is activated, the serial clock signal (SCL, Mod Def 1) is generated by the host. The positive edge clocks data into the SFP transceiver into those segments of the E2 PROM that are not write-protected. The negative edge clocks data from the SFP transceiver. The serial data signal (SDA, Mod Def 2) is bi-directional for serial data transfer. The host uses SDA in conjunction with SCL to mark the start and end of serial protocol activation. The memories are organized as a series of 8-bit data words that can be addressed individually or sequentially. For more information, please see the SFF-8472 documentation and Finisar Application Note AN-2030. FeaturesHot-pluggable SFP+ footprintSupports rate selectable 1.25 Gb/s or 9.95 to 10.3 Gb/s bit ratesPower dissipation < 1WRoHS-6 compliant (lead-free)Commercial temperature range -5°C to 70°CSingle 3.3V power supplyMaximum link length of 400m on OM4 MMFUncooled 850nm VCSEL laserReceiver limiting electrical interfaceDuplex LC connectorBuilt-in digital diagnostic functions Applications1000BASE-SX 1G Ethernet10GBASE-SR/SW 10G Ethernet DatasheetYou can download the datasheet from the link given below:FTLX8574D3BCV-Datasheet SpecificationsProduct Category:Fiber Optic Transmitters, Receivers, TransceiversProduct:TransceiversWavelength:850 nmData Rate:10.3 GBdFiber Type:MultimodeRise Time:28 psEmitting Source:VCSELOperating Supply Voltage:3.3 VMinimum Operating Temperature:- 5 ℃Maximum Operating Temperature:+ 70 ℃Application:Ethernet, Fibre ChannelConnector Type:LCTransmission Distance:400 mBrand:II-VI / FinisarMounting Style:Snap-InPackage / Case:56.5 mm x 13.7 mm x 8.5 mmProduct Type:Fiber Optic Transmitters, Receivers, TransceiversFactory Pack Quantity:10Subcategory:Fiber OpticTradename:FinisarUnit Weight:1.064404 oz ManufacturerFinisar Corporation is a manufacturer of optical communication components and subsystems.

And as they have the same size, your SFP transceiver will fit seamlessly into an SFP+ switch port and vice versa. However, the connection won't work as you expect it to. Or, worse even, it won't work at all. What does a SFP+ transceiver do?SFP+ is a faster version of the same form factor. It supports speeds up to 10Gbps, and it typically works across shorter distances.QSFP (quad small form-factor pluggable) is another transceiver with a range of support options. Ethernet, InfiniBand, SONET and fiber channels are all supported. Can I use SFP+ transceiver in SFP slot?When use SFP and SFP+ modules in your network, make sure the speed of both ends of the fiber link is the same. SFP modules may can be used in SFP+ slot, but a SFP can never be connected to a SFP+ module.
