Optoway SPS-4170RWG 1 *********************************************************************************************************************************************************************** SPS-4170RWG / SPS-4170BRWG / SPS-4170ARWG (RoHS Compliant) 6.144 Gbps / 1310 nm / 70 km Digital Diagnostic Multi-Rate CPRI SM SFP+ *********************************************************************************************************************************************************************** FEATURES DESCRIPTION l l l l l l l l l l l l The SPS-4170RWG series is a 1 to 6.25 Gb/s single-mode transceiver module for serial optical communication applications for a radio base station system. It is with the SFP+ 20-pin connector to allow hot plug capability. Digital diagnostic functions are available via an I2C. This module is designed for single mode fiber and operates at a nominal wavelength of 1310 nm. The transmitter section uses a 1310 nm multiple quantum well DFB laser and is a class 1 laser compliant according to International Safety Standard IEC-60825. The receiver section uses an integrated InGaAs detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC. CPRI / OBSAI Compatible Optical Interface 1 G to 6.25 G Multi-rate Specification Compliant to SFP+ MSA Link Distance up to 70 km SMF SFF-8472 Digital Diagnostic Function AC/AC Coupling according to MSA Single +3.3 V Power Supply RoHS 6/6 Compliant 0 to 70oC Operating: SPS-4170RWG -10 to 85oC Operating: SPS-4170BRWG -40 to 85oC Operating: SPS-4170ARWG Class 1 Laser International Safety Standard IEC 60825 Compliant APPLICATIONS l Radio Base Station l OBSAI rates 6.144 Gb/s, 3.072 Gb/s, and 1.563 Gb/s l CPRI rates 4.9152 Gb/s, 2.4576 Gb/s, and 1.2288 Gb/s 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.
