SFP transceiver for Gigabit Ethernet

This AddOn ITFZTCHLX-AO module is a hot-swappable SFP transceiver built for 1 Gbps Gigabit Ethernet links over optical fibre. It fits network equipment that accepts standard mini-GBIC form-factor modules. The single LC port carries 1000Base-LX signals for long-reach connections. Buyers who need multi-rate or copper interfaces cannot use this module.

Hot-swappable design changes installation

The hot-swappable power adapter lets technicians insert or remove the transceiver without powering down the switch or router. That capability reduces planned downtime during upgrades or fault isolation. No bundled software or licences accompany the hardware, so configuration relies entirely on the host device's operating system.

1 Gbps long-reach capacity and headroom

The transceiver delivers a 1 Gbps transfer rate over 1000Base-LX single-mode fibre, suited to campus or metro spans within the LX distance budget. It does not support 10 Gbps or wavelength-division multiplexing, so links that require higher throughput or dense channel counts need different optics. Weight is .4 pounds.

Questions about this item

When will the LC connector on the ITFZTCHLX-AO need cleaning or replacement?

The LC connector should be inspected and cleaned with a fiber scope and lint-free wipes whenever insertion loss rises; no fixed replacement interval is defined for the transceiver itself.

What limits sustained throughput on the 1000Base-LX link?

The 1 gigabit-per-second line rate is the hard ceiling; latency and distance on the single-mode fiber become the practical constraints once the link is saturated.

How much heat and power does the module add when running continuously?

The hot-swappable SFP draws only the standard low-power budget for a 1 Gbps transceiver and adds negligible heat inside the switch chassis.
