Delta LCP-1250B4QSRBTE 1.25Gbps 1310nm 10km SFP Transceiver

The Delta LCP-1250B4QSRBTE is a high-performance Small Form-Factor Pluggable (SFP) optical transceiver module designed for Gigabit Ethernet (1000BASE-LX) and 1x Fibre Channel applications. Operating at a nominal wavelength of 1310 nm, this module is equipped with a high-reliability Fabry-Perot (FP) laser transmitter and a high-sensitivity PIN photodiode receiver. It is specifically engineered for long-reach data transmission over single-mode fiber (SMF), supporting link distances of up to 10 kilometers. This makes it an ideal solution for metropolitan area networks (MAN), campus backbones, and inter-building optical links where reliable high-speed connectivity is required.The transceiver is fully compliant with the SFP Multi-Source Agreement (MSA) and IEEE 802.3z standards, ensuring seamless interoperability with switches, routers, and other telecommunications equipment from various manufacturers. It features a duplex LC optical interface and operates from a single 3.3V power supply with a low power consumption profile. The LCP-1250B4QSRBTE includes integrated Digital Diagnostic Monitoring (DDM), providing real-time telemetry for operational parameters such as laser bias current, transmitted optical power, received optical power, internal temperature, and supply voltage.

Built for carrier-grade reliability, the module is housed in a durable metallic enclosure that provides excellent electromagnetic interference (EMI) shielding and mechanical integrity. It is hot-pluggable, allowing for network expansion or maintenance without the need for system downtime. The module is optimized for stable performance across its operational temperature range and is RoHS compliant. The "BTE" suffix typically indicates an extended or industrial temperature range capability, making it suitable for deployment in non-environmentally controlled cabinets and demanding outdoor-rated enclosures.
