Juniper JX-SFP-1GE-LX  Compatible 1000BASE-LX SFP Optical Transceiver Module | HYTOPTODEVICE

Full Compatibility List and Supported Devices of  Fiber Optic Transceiver

The JX-SFP-1GE-LX compatible transceiver is pre-coded with authentic Juniper Junos OS vendor strings, guaranteeing native plug-and-play identification without CLI hardware warnings across:

1.Juniper EX Series Ethernet Switches

• Fixed Configuration Access Switches: EX2200, EX2300, EX3300, EX3400, EX4200, EX4300 Series

• Note: When used on 10GE SFP+ uplink ports, Junos allows this module to operate seamlessly, but it may require a manual speed configuration depending on the exact switch model (e.g., set chassis fpc 0 pic 1 port 0 speed 1g).

2.Juniper SRX Series Services Gateways (Firewalls)

• Branch & Enterprise Firewalls: SRX100, SRX110, SRX210, SRX220, SRX240, SRX300, SRX320, SRX340, SRX345, SRX550

• Campus Backbone Interconnections: Connecting core Junos aggregation switches across building facilities separated by up to 10 kilometers (6.2 miles) using underground Single-Mode fiber paths.

• Branch Office WAN Uplinks: Populating vacant SFP slots on Juniper SRX enterprise firewalls to create high-speed, long-distance fiber WAN links to local ISPs or centralized corporate headquarters.

• Legacy Fiber Optimization: Allowing IT infrastructure to bridge older Multi-Mode horizontal cables with modern Single-Mode links using the exact same transceiver model across the entire deployment.
  
  

FAQ for Transceiver Module

Q1:Can the Juniper Networks JX-SFP-1GE-LX be used in Juniper Networks 10G SFP+ or 25G SFP28 ports?
A1: Yes, absolutely. The Juniper JX-SFP-1GE-LX uses the standard 1000BASE-X fiber protocol, which is natively understood by Juniper’s 10G/25G hardware interfaces. To bring the link up, you must configure the port speed down to 1G via the Juniper EOS command line using: speed forced 1000full.

Q2:Does this Juniper Networks JX-SFP-1GE-LX support Digital Diagnostic Monitoring (DDM)?
A2:Yes. Our JX-SFP-1GE-LX supports DDM/DOM,allowing network administrators to monitor real-time metrics such as TX/RX optical power,bias current, voltage and temperature via the show transceiver command.

Q3: Can I pair an  Juniper JX-SFP-1GE-LX on one side of a link with a multimode transceiver on the other side? A3: No, this will not work. An LX module operates at a 1310nm long wavelength, while an SX module uses an 850nm short wavelength. Because they speak on completely different light frequencies, they will never establish an optical link. Both sides must use matching wavelengths.

Q4:What fiber cable is required for the JX-SFP-1GE-LX optical transceiver?
A4:This module uses wavelength 1310nm to transmit traffic over Single-Mode Fiber (SMF) with an LC Duplex connector. 

Q5:Do I need to turn off my Juniper switch before inserting the JX-SFP-1GE-LX optical transceiver?
A5: No, the JX-SFP-1GE-LX is hot-pluggable module. You can insert or extract the module while the system is powered on and handling active production traffic, without causing any electrical faults or downtime.

Q6:Can this module auto-negotiate its speed down to 100Mbps Fast Ethernet?
A6: No, the JX-SFP-1GE-LX does not support 10/100 Mbps old-legacy connectivity. It is a fixed-speed optical module designed to operate exclusively at 1 Gbps (1000 Mbps) line rates.
