H3C SFP-GE-LX-SM1310-20 Compatible 1000BASE-LX/LH SFP 1310nm 20km DOM Duplex LC SMF Transceiver Module

The H3C SFP-GE-LX-SM1310-20 compatible SFP transceiver can handle links up to 20km over LC duplex SMF fiber. It’s tested for use with H3C switches, routers, servers, and NICs. This hot-swappable 1G SFP transceiver is energy-efficient and perfect for ISP Gigabit Ethernet, Enterprise LAN & SAN Networks, Data Center LAN & SAN Networks, and other optical connections.

H3C SFP-GE-LX-SM1310-20 Compatible 1000BASE-LX/LH SFP Transceiver Module (SMF, 1310nm, 20km, LC, DOM)

The H3C SFP-GE-LX-SM1310-20 compatible optical transceiver is a versatile module designed for 1000BASE Ethernet. It offers a 1Gbps data rate and can transmit data up to 20km over single-mode fiber (SMF) using a 1310nm wavelength.

This transceiver follows important industry standards like the SFP Multi-Source Agreement (MSA), IEEE 802.3z 1000BASE-LX20, and SERDES standard. It uses a 20-pin edge type electrical connector that’s MSA compliant, and for the optical side, it uses a Duplex LC connector.

This full-duplex SFP transceiver is equipped with a highly reliable FP transmitter and PIN photo detector, ensuring top-notch performance at a 1 Gbps data rate. It also includes a built-in Digital Diagnostic Monitoring (DDM) feature for real-time performance monitoring using a 2-wire Interface (TWI/I2C).

Our modules come pre-programmed for compatibility and perform just as well as the original H3C SFP-GE-LX-SM1310-20 transceivers, making them a reliable and cost-effective choice.
