Optoway SPS-3131WG 1 *********************************************************************************************************************************************************************** SPS-3131WG (RoHS Compliant) 3.3V / 1310 nm / 125/155 Mbps Digital Diagnostic LC SFP SINGLE-MODE TRANSCEIVER ********************************************************************************************************************************************************************** FEATURES DESCRIPTION l l l l l l l l l l The SPS-3131WG series single mode transceivers is small form factor pluggable module for bi-directional serial optical data communications such as SONET OC-3 / SDH STM-1 and Fast Ethernet. 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 multiple quantum well 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. Hot-Pluggable SFP Footprint LC Optical Transceiver Small Form-Factor Pluggable (SFP) MSA compatible Compliant with SONET OC-3 IR / SDH STM-1 (S-1.1) SFF-8472 Digital Diagnostic Function AC/AC Coupling according to MSA Distance up to 30 km Single +3.3 V Power Supply RoHS Compliant 0 to 70oC Operating Case Temperature Class 1 Laser International Safety Standard IEC-60825 Compliant APPLICATIONS l ATM Switches and Routers l SONET / SDH Switch Infrastructure l Fast Ethernet Applications 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, MOD-DEF(1:2) appear as no connector (NC) and MOD-DEF(0) 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.
