PRE-SFP-B34-40 1.25Gb/s Bi-Di Transceiver, 1310/1490nm Tx/Rx, 40km, DDM Product Features Single-mode Bi-directional transmission at 1310nm, used as a pair with PRE-SFP-B43-40 1.25Gb/s Data Links up to 40 km on 9/125 µm SMF MSA Package with Built-in WDM and LC receptacle Hot-Pluggable Single +3.3V Power Supply Metal Enclosure, Excellent EMI ESD Protection Isolation > 30 dB, Cross Talk < -45dB Industrial (-40°C to 85°C), Extended (-5°C to 85°C) or Commercial (0°C to 70°C ) operating temperature Compliance Applications SFF-8472 Compliant Monitoring Interface IEEE Std. 802.3z RoHS compliant Class 1 Laser Safety per EN (IEC) 60825 regulations Gigabit Ethernet Fibre Channel WDM Applications Description Precision Optical Transceivers PRE-SFP-B34-40 is a high performance, cost effective Bi-directional transceiver with a single LC optical interface and a built-in WDM for data communication applications. PRE-SFP-B34-40 operates at 1310 nm (Tx) and 1490 nm (Rx) nominal wavelengths and includes a standard AC coupled CML for high speed signal and LVTTL control and monitor signals. The DFB laser transmitter and IC driver with temperature compensation and automatic power control circuit makes the transmitter output power and extinction ration stable across the operating temperature range. The Receiver consists of an InGaAs photodiode and transimpedance with AGC for wide dynamic rage. A 21dB link budget ensures 1000Base Ethernet transmission up to 40 km.
