ZKTel's BIDI SFP transceivers are designed for bi-directional 10G serial optical data communications such as IEEE 802.3ae 10GBASE-BX by using 1330(1270nm) transmitter and 1270(1330) nm receiver. The transceiver consists of two sections: The transmitter section uses a multiple quantum well 1330(1270) nm DFB laser and is a class 1 laser compliant according to International Safety Standard IEC 60825. The receiver section uses an integrated 1270(1330) nm detector preamplifier (IDP) mounted in an optical header and a limiting post-amplifier IC.Features:• One Fiber Bi-Di SFP Optical Transceiver, Bidi WDM SFP • Up to 10.3 Gbps Bi-directional Data Links• Fully Compliant with SFP MSA• Compliant to IEEE 802.3ae 10GBASE-BX• SFF-8472 Digital Diagnostic Function• Simplex LC Connector• 1330TX/1270RX and 1270TX/1330RX• Distance Up to 60 km• Only Required 3.3 V Power Supply• RoHS Compliant• -5 to 70oC OperatingApplication:• 10GBASE-BX at 10.3125 Gb/s• 10GBASE-BX at 9.953 Gb/s• 1000 Base-LX Ethernet• 8XFC at 8.5Gbps• 4XFC at 4.25Gpbs• 2XFC at 2.125Gpbs• 1xFC at 1.0625Gbps .table{ border-collapse:collapse;} .table td, .table th{ border:1px solid #cdcdcd; padding:5px;} Package Part No. Data Rate  Range Wavelength Optical  Components Distance  Range Conne ctor Case  Temp.
