HP JD119B X120 SFP Transceiver 1000base-lx LC

SKU CH-1M02-850ED

SFP transceiver module delivers 1 Gbps over 1000base-lx with LC connector

  • Product typeTransceiver
  • Gigabit Ethernet link at 1 Gbps data rate
  • 1000base-lx long-wavelength optics for single-mode fibre
  • LC duplex connector ensures secure fibre patching
  • Hot-pluggable SFP mini-GBIC form factor fits standard slots
  • HP JD119B X120 module validated for compatible network gear

HP JD119B X120 Transceiver

The HP JD119B X120 is a plug-in SFP transceiver module built for Gigabit Ethernet links. It targets network engineers and system integrators who need a hot-swappable optics solution for long-reach single-mode fibre runs.

LC Connector and 1000base-lx Cabling

The module ships with an LC duplex interface tuned for 1000base-lx signalling, so installers can patch directly into standard single-mode patch cords without adapters. Its plug-in enclosure slides into any SFP mini-GBIC slot, requiring no extra brackets or configuration tools.

1 Gbps Data Rate Headroom

At a 1 Gbps line rate the transceiver comfortably handles campus backbone links and metro-access circuits within the 1000base-lx reach envelope. It runs out of headroom when aggregate throughput demands exceed the single Gigabit Ethernet channel or when multimode fibre plants replace the specified single-mode infrastructure.

Questions about this item

How often does the LC connector on the JD119B need cleaning or replacement?

The LC connector on this SFP module is a passive optical interface. It requires no scheduled replacement; clean the ferrule with a lint-free wipe and isopropyl alcohol only when inserting or removing cables.

What limits the 1 Gbps link on the X120 during sustained traffic?

The 1000base-lx standard caps the data rate at 1 Gbps full-duplex. The bottleneck is the Gigabit Ethernet protocol itself, not the transceiver.

Does the JD119B generate noticeable heat or noise when running continuously?

As a passive plug-in module with no fan or active cooling, the X120 operates silently. Heat output is minimal and handled by the host switch's airflow.
