Vláknový transceiver modul BlueOptics GLC-ZX-SMD-120-BO 120000 m

The BlueOptics GLC-ZX-SMD-120-BO is a single‑mode SFP fiber optic transceiver module designed for long-distance data transmission up to 120,000 m (120 km). Housed in an aluminium casing and weighing approximately 20 g, this 1000BASE‑ZX module uses LC duplex connectivity and operates at 1550 nm for both transmit and receive, providing support for 1.25 Gbit/s optical links over single‑mode fiber. The module follows MSA SFP form‑factor standards and is intended for use in network equipment that accepts standard SFP 1000BASE‑ZX transceivers.

Advantages

The compact aluminium housing offers a lightweight but durable solution for long‑reach fiber links while limiting electromagnetic interference. Designed to meet SFP and MSA specifications, the module supports common high‑speed protocols such as Ethernet and Fibre Channel over Ethernet at gigabit speeds. Built with optics and IC components sourced to meet industry quality expectations, the module provides stable optical performance for extended operational lifetimes and reduced maintenance.

Key specifications

How to use

Insert the SFP transceiver into a compatible SFP slot on switches, routers or storage devices while the host device is powered down or following the vendor’s hot‑plug instructions. Connect LC duplex single‑mode fiber patch cords to the transceiver, ensuring proper transmit/receive orientation. Verify link status and negotiated speed in the host device management interface. If available and supported by the host, enable Digital Diagnostic Monitoring (DDM/DOM) to view real‑time module parameters such as optical power, temperature and supply voltage for remote diagnostics.

Recommendations

Use high‑quality single‑mode LC patch cords and maintain clean connector endfaces to achieve the specified range and optimal signal quality. Confirm that the target hardware supports 1000BASE‑ZX SFP modules and, if required, DDM/DOM features. For long spans, consider end‑to‑end power budget and attenuation (splices, connectors, fiber type) to ensure reliable operation over the full distance.
