DATASHEET 4.2 SO-SFP-10GE-ER SFP+, 10GBase-ER, 1550nm, SM, DDM, 14.8dB, 40km OVERVIEW The SO-SFP-10GE-ER series single mode transceiver is small form factor pluggable module for duplex optical data communications up to 10G. It is with the SFP+ 20-pin connector to allow hot plug capability. This module is designed for single mode fiber and operates at a nominal wavelength of 1550 nm. The transmitter section uses a 1550nm EML, which is 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. PRODUCT FEATURES • 1550nm EML transmitter • Distance up to 40km over SMF • Single 3.3V Power supply and TTL logic interface • Duplex LC connector interface • Hot-Pluggable • Power dissipation < 1.5 W (Typical < 1W) • Dispersion tolerance 800 ps/nm • Case operation temperature: Standard: -5°C to +70°C Industrial: -40°C TO +85°C • Compliant with SFF-8431 MSA • Compliant with SFF-8432 MSA • Compliant with SFF-8472 MSA APPLICATIONS • 10GBASE-ER/EW • 8G/10G FC • Other optical links ORDERING INFORMATION Part Number Description SO-SFP-10GE-ER SFP+, 10GBase-ER, 1550nm, SM, DDM, 14.8dB, 40km SO-SFP-10GE-ER-I SFP+, 10GBase-ER, 1550nm, SM, DDM, 14.8dB, 40km ind.temp.
