It is with the SFP 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C series bus specified in the SFP MSA SFF-8472. The transmitter section uses a multiple quantum well 1270 nm DFB laser and is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses an integrated 1330 nm detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. 1-Fiber Bi-Directional SFP Optical Transceiver Up to 8.5 Gbps Bi-directional Data Links Compliant with SFP+ MSA Compliant with Fibre Channel FC-PI-4 800-SM-LC Compliant with 4G and 2G Fibre Channel SFF-8472 Digital Diagnostic Function Simplex LC Connector 1270 nm DFB LD Transmitter 1330 nm Receiver Distance Up to 40 km AC/AC Coupling according to MSA Single +3.3 V Power Supply RoHS Compliant 0 to 70oC Operating: SPB-4840LWG -10 to 85oC Operating: SPB-4840BLWG Class 1 Laser International Safety Standard IEC 60825 Compliant APPLICATIONS l 8G Fibre Channel Links LASER SAFETY This single mode transceiver is a Class 1 laser product. It complies with IEC 60825 and FDA 21 CFR 1040.10 and 1040.11. The transceiver must be operated within the specified temperature and voltage limits. The optical ports of the module shall be terminated with an optical connector or with a dust plug.

For this definition, upon power up, SDA and SDL appear as no connector (NC) and MOD-ABS is TTL LOW. When the host system detects this condition, it activates the serial protocol. The protocol uses the 2-wire serial CMOS E 2PROM protocol of the ATMEL AT24C01A/02/04 family of components. ********************************************************************************************************************************************************************** OPTOWAY TECHNOLOGY INC.
