Juniper-compatible SFP module

The RX10KMSFPST is a new SFP transceiver built, programmed and tested for Juniper switches and routers. It provides 1 GbE connectivity over single-mode or multi-mode fiber for 1000BASE-LX networks. Network engineers maintaining Juniper infrastructure use it to link sites or buildings without replacing existing hardware.

Upgrade from shorter-reach optics

This module replaces transceivers limited to a few hundred metres by extending the link to 10 km (6.2 mi) at 1310 nm wavelength. The jump is worth it when campus or metro segments exceed the range of standard SX optics and a full router refresh is not planned. Builders who need a second card or a different vendor platform cannot use this module.

Sustained 1 Gbps over long fibre

The transceiver maintains 1 Gbps transfer rate across the full 10 km distance using LC connectors on SMF or MMF. It operates continuously at line rate without the throughput drop that short-burst tests can hide. The 1310 nm laser and receiver pair is qualified for dependable long-term operation in Juniper chassis.

Questions about this item

What type of fiber connector does the RX10KMSFPST use?

The module uses an LC duplex connector for single-mode or multi-mode fiber.

How is the SFP transceiver installed in a Juniper switch?

Slide the module into an open SFP port until it clicks, then connect the LC cables; the common mistake is not fully seating the latch.

When should the optical interfaces be cleaned?

Clean the LC ferrules with a lint-free wipe and isopropyl alcohol before first use and whenever signal loss is observed.
