The JX-SFP-1GE-LX40K-C is a Juniper-compatible 1000BASE-LX SFP optical transceiver supporting Gigabit Ethernet up to 40 km over single-mode fiber.
This SFP is compatible with Juniper MX, EX, QFX and SRX series routers and switches that support 1 Gbps SFP modules.
It supports single-mode fiber (SMF) with a maximum optical reach of 40 kilometers.
The transceiver operates at a nominal wavelength of 1310 nm for both transmit and receive.
Yes. The module supports hot-plug capability, allowing installation or removal without powering down the host device.
It supports a data rate of 1.25 Gbps for 1000BASE-LX Ethernet applications.
Yes. It features Digital Optical Monitoring (DOM) to report real-time parameters such as temperature, voltage, and optical power.
The module uses an LC duplex connector for single-mode fiber connections.
The typical power dissipation is less than 1.0 W, ensuring efficient operation and low heat generation.
Operating temperature ranges from 0 °C to 70 °C; storage temperature ranges from –40 °C to 85 °C.
Yes. It meets IEEE 802.3z (1000BASE-LX), MSA SFF-8472 and RoHS compliance requirements.
Insert the SFP module into an available SFP port until it clicks, then connect LC fiber patch cables and verify the link status LED.
The typical power budget is 9 dB, supporting spans up to 40 km with standard single-mode fiber.
Yes. It is backed by a one-year limited warranty covering manufacturing defects and performance compliance.
Each module is shipped in an antistatic bag with protective caps, securely packaged in a padded box to prevent transit damage.
Check fiber polarity, clean LC connectors, verify SFP compatibility, and ensure both ends use 1000BASE-LX modules.
