Zyxel SFP-LX-10-E network transceiver module Fiber optic 1000 Mbit/s 1310 nm

The Zyxel SFP-LX-10-E is a hot-pluggable fiber optic transceiver module designed for 1 Gbit/s network links. The compact SFP form factor (13.4 x 56 x 12.4 mm) and low power requirements make it suitable for integration into Zyxel-compatible switches and network equipment. It operates at a wavelength of 1310 nm and supports standard single-strand and dual-strand fiber deployments depending on the selected transceiver type.

Advantages

Independent, hot-pluggable transceiver design provides maximum maintenance flexibility: modules can be added, replaced, or upgraded without removing the entire device. Bi-directional, dual-wavelength capability allows communications over a single fiber strand, reducing the need to lay additional fiber when expanding capacity. The module supports Digital Diagnostic Monitoring Interface (DDMI) to access operating parameters, enable soft control and monitoring of SFP I/O signals, and allow digital alarms and warnings. A complete accessory portfolio (1G SFP, 10G SFP+, 10G DAC) ensures compatibility with various installation needs.

Suitable for

• 1 Gbit/s fiber uplinks for switches and routers
• Network infrastructure expansion without additional fiber cabling
• Environments requiring hot-pluggable, field-replaceable transceivers
• Systems that use DDMI for monitoring and diagnostics

How to use

Insert the SFP-LX-10-E module into a compatible SFP slot on a Zyxel or other compatible switch/router while the device is powered on or off, following the equipment manufacturer’s hot-plug guidelines. Connect the fiber cable—single-strand for bi-directional modules or duplex for standard modules—ensuring correct connector type and polarity. Verify link status and, if available, monitor DDMI parameters through the switch management interface to confirm optical power levels and operating status.

Recommendations

Use this transceiver in environments that match the specified electrical and optical parameters. When replacing or upgrading modules, choose the correct single-strand bi-directional or duplex variant according to your fiber plant. Regularly monitor DDMI readings to detect signal degradation and plan maintenance before outages occur.
