SFP Network Transceiver CBO EX-SFP-1GE-LX40K-1550-BO 1 Gbps, 1550 nm, single‑mode, up to 40 km

CBO EX-SFP-1GE-LX40K-1550-BO is an SFP form-factor optical transceiver that supports 1 Gbps data transmission over single-mode fiber at a 1550 nm wavelength. Engineered for long-reach links up to 40 km, the module offers a hot-pluggable interface for switches, routers and other optical network equipment. The compact design and industry-standard SFP footprint enable easy installation in gigabit network ports, making it suitable for metro, carrier and enterprise fiber connections that require reliable long-distance transport.

Advantages

The transceiver delivers long-distance performance up to 40 km on single-mode fiber while maintaining a standard 1 Gbps data rate. Its 1550 nm wavelength is optimized for minimized attenuation over extended distances. The SFP hot-pluggable module simplifies upgrades and maintenance without powering down equipment. Built to industry form-factor standards, it ensures broad compatibility with networking devices that accept SFP optics and supports straightforward replacement and deployment.

Suitable for

• Long-reach fiber links between buildings or sites within metro and campus networks
• Carrier and service provider aggregation and access links
• Enterprise WAN connections where single-mode fiber is used
• Link extension between switches, routers and optical transport equipment

Key specifications

• Data rate: 1 Gbps
• Optical wavelength: 1550 nm
• Fiber type: single-mode fiber (SMF)
• Maximum link distance: up to 40 km (dependent on fiber quality and link budget)
• Form factor: SFP (hot-pluggable)
• Connector type: LC duplex

How to use

Insert the SFP transceiver into an appropriate SFP port on a switch, router or optical device while the host device is powered on or off according to manufacturer guidance. Connect single-mode fiber using LC duplex connectors, ensuring proper polarity and clean fiber endfaces. Verify link status through the host device’s port indicators or management interface and confirm negotiated speed is 1 Gbps. For stable operation, check that the fiber route and link budget are within the module’s maximum distance capability.

Recommendations

To maintain optimal performance, clean connectors before mating and use single-mode fiber runs with appropriate attenuation and dispersion characteristics. Confirm compatibility with the equipment vendor’s supported optics list when possible and perform firmware or configuration checks on network devices to enable the transceiver’s full feature set.
