Questions & Answers
What is the SRX-SFP-1GE-SX-ET module?
The SRX-SFP-1GE-SX-ET is an extended-temperature, small-form-factor pluggable (SFP) transceiver that delivers 1000BASE-SX Gigabit Ethernet over multimode fiber.
Which fiber type does the SRX-SFP-1GE-SX-ET support?
This SFP supports 50/125 µm and 62.5/125 µm multimode fiber, providing reliable 1000 Mbps connectivity up to 550 meters.
What temperature range does the extended-temperature rating cover?
The module operates reliably from –40 °C to +85 °C, making it ideal for harsh-environment and industrial applications.
Is the SRX-SFP-1GE-SX-ET hot-pluggable?
Yes. It is fully hot-pluggable, allowing safe insertion and removal without powering down the host device.
Which networking devices are compatible with this SFP?
It is compatible with Juniper SRX Series firewalls, EX Series switches, QFX Series devices, and any 1000BASE-SX-capable Gigabit Ethernet port.
