Optický SFP transceiver CBO 61557-BO 1250 Mbit/s LC LX

CBO 61557-BO is a fiber optic SFP transceiver designed for single-mode links, supporting a data rate of 1250 Mbit/s with an LC duplex connector and LX long‑reach optics. The module fits standard SFP ports and provides a hot‑pluggable interface suitable for extending Ethernet and telecom connections over greater distances while maintaining compatibility with common networking equipment.

Advantages

The transceiver offers compact SFP form factor convenience and hot‑swappable installation without powering down network devices. LX optics enable extended reach over single‑mode fiber, and the LC connector ensures widespread physical compatibility. The module’s fixed 1250 Mbit/s rate and standardized interface simplify deployment and interoperability in mixed-vendor environments.

Suitable for

• Extending Ethernet links over single‑mode fiber
• Connecting telecom equipment and switches with SFP ports
• Replacing or upgrading existing fiber transceivers for longer reach
• Point‑to‑point links in campus and metropolitan networks

Key specifications

• Data rate: 1250 Mbit/s
• Optical type: LX long‑reach single‑mode optics
• Connector: LC duplex
• Form factor: SFP (hot‑pluggable)
• Fiber type: single‑mode fiber (SMF)

How to use

Install the transceiver into an empty SFP port on compatible network equipment until it clicks into place. Connect LC duplex single‑mode fiber patch cords to the transmit and receive ports, ensuring correct orientation. The module is hot‑pluggable, so it can be inserted or removed while the host device remains powered; observe manufacturer guidance for link negotiation and interface configuration. Configure the host port for the appropriate speed and duplex settings if required by your equipment.

Recommendations

Verify compatibility with the switch or router vendor and check fiber link budget and connector cleanliness before installation. Use single‑mode LC patch cords, follow ESD precautions during handling, and confirm optical power levels and link status after connecting to ensure reliable long‑reach performance.
