Description

The Juniper QSFP-100G-ER4L is a 100GBASE-ER4 Lite QSFP28 single-mode fibre transceiver engineered for extended-reach data centre interconnects and enterprise core network links up to 40 km. Operating over LC duplex connectors at 1310 nm using CWDM4 wavelengths, it delivers full 100 Gbps throughput across standard SMF with a standard temperature operating range of 0°C to 70°C. It is purpose-built for deployment in Juniper QFX and PTX series platforms requiring long-haul 100G connectivity without the cost of full ER4 optics.

The ER4 Lite specification reduces launch power requirements compared to full ER4, making it cost-effective for campus and metro interconnects where the full 40 km reach is still essential. Compatible with Juniper's native optics ecosystem, this transceiver ships with a Juniper-coded EEPROM for seamless plug-and-play operation.

FAQs

Q: What is the maximum transmission distance of the QSFP-100G-ER4L?
A: The QSFP-100G-ER4L supports a maximum reach of 40 km over standard single-mode fibre (SMF) using LC duplex connectors, making it suitable for metro and campus interconnects.

Q: What is the difference between ER4 and ER4 Lite (ER4L)?
A: The ER4 Lite variant has a slightly reduced optical launch power compared to full ER4, which lowers cost while still supporting the full 40 km reach on clean SMF links. It is ideal for most practical long-reach deployments.

Q: Which Juniper platforms is this transceiver compatible with?
A: The QSFP-100G-ER4L is designed for Juniper QFX and PTX series switches and routers that support QSFP28 100G ports. Always verify platform compatibility with your specific Juniper device's transceiver compatibility matrix.

Q: Is this transceiver Juniper-coded for plug-and-play operation?
A: Yes, the QSFP-100G-ER4L is a Juniper-branded optic with a Juniper-coded EEPROM, ensuring it is recognised natively by Juniper equipment without requiring any special configuration or compatibility workarounds.

Q: Can I purchase this transceiver in Australia through IP Trading?
A: Yes, IP Trading stocks Juniper optics including the QSFP-100G-ER4L and ships across Australia. Visit iptrading.com.au to check availability and place your order for fast local delivery.

Q: What fibre and connector type does the QSFP-100G-ER4L require?
A: This transceiver requires single-mode fibre (SMF) with LC duplex connectors. It is not compatible with multimode fibre or MPO/MTP connectors.
