Flawless FE multi-mode support. These 2km modules are perfect for our legacy ERX equipment. Stable 100Mbps throughput and easy installation.
Reliable and consistent. Recognized immediately by the ERX series. A perfect solution for maintaining older multi-mode fiber infrastructure.
Excellent build quality. These FE optics provide stable signaling and are very easy to deploy. Reliable performance for specialized networking.
Top-notch compatibility. No issues connecting to our legacy hardware. Significant savings while maintaining high reliability and signal integrity.
Professional FX optics. They run cool and deliver steady performance. A trustworthy choice for 100BASE-FX links on ERX routers.
The RX-FXMM-SFP-C is a 100Base-FX small form-factor pluggable (SFP) transceiver with Digital Optical Monitoring (DOM) that supports up to 2 km over multimode fiber and is fully compatible with Juniper ERX series routers.
Yes. This SFP adapter has been tested and certified for full interoperability with all Juniper ERX series platforms, ensuring plug-and-play operation.
The module supports multimode fiber transmission distances of up to 2 km at 100 Mbps using 50/125 µm or 62.5/125 µm fiber.
It supports a fixed 100 Mbps full-duplex data rate, ideal for legacy Fast Ethernet and industrial network segments.
Yes. Integrated DOM provides real-time monitoring of optical power, temperature, voltage and laser bias current via the SFF-8472 interface.
Use standard 100Base-FX multimode fiber cable with 50/125 µm or 62.5/125 µm core/cladding dimensions.
The transceiver operates at a wavelength of 1310 nm, optimized for reliable multimode fiber performance.
The module operates reliably from 0 °C to 70 °C (32 °F to 158 °F) for standard commercial-grade applications.
Simply insert the SFP transceiver into an available SFP slot on your Juniper ERX router until it clicks into place; the device will auto-detect and configure the link.
Yes. The SFP transceiver supports hot-swap installation and removal without powering down the host device.
Power consumption is minimal, typically less than 1 W, making it energy-efficient for continuous operation.
Yes. It includes a one-year limited warranty covering manufacturing defects and guaranteed performance.
Yes. We offer a 30-day return policy on unused, unopened modules; please contact our support team for an RMA.
Ideal for campus backbones, industrial Ethernet, and metro network aggregation where 2 km multimode fiber links are required.
The module supports auto-negotiation on the host port and autosenses fiber presence, but it does not require MDI/MDIX settings on the fiber interface.
While designed for Juniper ERX, many customers report successful interoperability in other SFP-enabled platforms, though compatibility is not guaranteed.
Use your host router’s CLI or SNMP management tools to query SFF-8472 registers for live optical power, temperature, voltage and bias current readings.
