The SFP 1.25Gb/s LX optical transceiver

Our comaptible SFP 1.25Gb/s module includes: multimode optical modules GLC-SX-MM; Single-mode optical module GLC-LH-SM, GLC-ZX-SM; SFP copper module GLC-T  ; DWDM/CWDM SFP; 2.125G SFP transceiver module; 4G SFP module; BIDI SFP optical transceiver; SFP with DDM transceiver such as SFP-GE-S .Optcore 1250Mbps SFP LX is a high performance and cost effective optical transceiver module. It is designed to
meet Gigabit Ethernet application. The SFP 1.25Gb/s LX optical transceiver consists of two sections: the transmitter section consists of a high reliability 1310nm FP LD with monitor photo detector (MPD) in eye safety;the receiver section consists of a high-speed InGaAs PIN photodiode (PD) and trans-impedance preamplifier.The output of the PD drives the post-amplification, quantizing, and optical signal detection circuits. The receiver is built in the LOS monitoring function. For further information, please see SFP MSA and SFF-8472 standard.The SFP 1.25Gb/s optical transceiver module includes internal circuit components to filter power supply noise.Under some conditions of EMI and power supply noise, external power supply filtering may be necessary.If receiver sensitivity is found to be degraded by powersupply noise, the filter network illustrated in the following figure may be used to improve performance. The values of the filter components are generalrecommendations and may be changed to suit a particular system environment.Shielded inductors are recommended.
