Juniper EX-SFP-1GE-LH Compatible 1000BASE-ZX SFP 1550nm 80km DDM Duplex LC/UPC SMF Optical Transceiver Module

The HYTOPTODEVICE Juniper EX-SFP-1GE-LH compatible SFP is rigorously tested for compatibility with:

• Juniper EX Series Switches: EX2200, EX2300, EX3300, EX3400, EX4200, EX4300, EX4550, EX4600, and EX9200 series.

• Juniper QFX Series: QFX5100 and QFX5110 (using 1G SFP ports).

• Juniper SRX & NFX Series: Compatible with many security and network services platforms requiring 1G LH optics.

• Legacy Juniper Hardware: Reliable performance in older EX-series chassis requiring specific LH-designated signatures.

• Metro Ethernet Backhaul: Connecting separate campus locations or remote municipal offices across city-wide fiber spans up to 80km.

• Service Provider Aggregation: Providing high-stability 1.25G fiber handoffs for regional ISPs in extended-reach environments.

• Secure Enterprise WAN: Reliable long-distance fiber interconnects for corporate headquarters and geographically dispersed branch offices.

FAQ for Juniper EX-SFP-1GE-LH Compatible SFP Transceiver

Q1: What is the difference between EX-SFP-1GE-LH and EX-SFP-1GE-ZX? A: In the Juniper EX series ecosystem, they are functionally identical (both 1550nm 80km). "LH" is simply the traditional Juniper nomenclature for "Long Haul." Our HYTOPTODEVICE module satisfies the coding requirements for both part numbers.

Q2: Will Junos OS recognize this as an authorized Juniper module? A: Yes. Our modules are programmed with authentic Juniper vendor signatures. Junos OS will identify the module as EX-SFP-1GE-LH, ensuring it initializes without port-blocking or "non-Juniper" alarm messages.

Q3: Can I check the optical power levels in the Junos CLI? A: Absolutely. Since our module supports DOM, you can use the command show interfaces diagnostics optics to view real-time TX/RX power levels and link health.

Q4: Do I need an optical attenuator for short-distance links? A: YES. This is a high-power laser designed for 80km. If your fiber link is shorter than 20km, you MUST use a 10dB-15dB LC optical attenuator to protect the sensitive optical receiver from permanent damage.

Q5: Will this 1G SFP work in a 10G SFP+ port? A: Yes. Most Juniper SFP+ ports are backward compatible. You may need to manually configure the interface speed to 1g if the port does not auto-negotiate.
