SFP transceiver module BlueOptics SFP-1GEZXLC-BO 1250 Mbit/s 1550 nm

The BlueOptics SFP-1GEZXLC-BO is an SFP fiber optic transceiver module designed for single‑mode links with a nominal wavelength of 1550 nm and a maximum data rate of 1250 Mbit/s (1000BASE‑ZX class). Housed in a compact metal case and operating from a 3.3 V supply, the module uses an LC duplex optical interface and weighs approximately 3 g. It is intended for use in SFP slots of network equipment that support 1000BASE‑ZX optics and provides a long‑reach single‑mode connection for switches, routers and other compatible hardware.

Advantages

The module offers a standardized SFP form factor for hot‑plug installation and conforms to industry MSA mechanical and electrical specifications. With optical transmission at 1550 nm it supports long‑distance single‑mode links and, when used in compatible systems, can carry Ethernet and related protocols at up to 1.25 Gbit/s. The metal housing provides mechanical protection and helps with heat dissipation, while the low weight makes it suitable for dense installations. Designed and tested for interoperability, the transceiver supports digital diagnostics monitoring (DDM/DOM) when the host hardware exposes that function.

Suitable for

• Long‑reach single‑mode Ethernet links (1000BASE‑ZX)
• Interconnection of switches and routers across metropolitan or campus networks
• High‑speed uplinks between data center racks and network aggregation points
• Replacement or upgrade of compatible SFP transceivers in supported hardware

How to use

Install the module into an empty SFP slot of compatible network equipment following the device manufacturer's installation instructions. Connect LC duplex single‑mode fiber patch cables to the transceiver, ensuring correct transmit/receive orientation. Verify that the host device recognizes the module and, if supported, enable or read out digital diagnostics (DDM/DOM) through the management interface to monitor optical parameters. Always perform a test link check and validate signal levels and protocol operation after installation.

Recommendations

For reliable long‑distance performance, use certified single‑mode fiber and LC duplex patch cords, keep connectors clean, and confirm compatibility with the host device. If digital diagnostics are required, ensure the network hardware supports DDM/DOM. Follow ESD precautions during handling and store the module in a protective container when not installed.
