SFP fiber optic transceiver CBO J4859C-LEG 1250 Mbit/s 1310 nm

The SFP fiber optic transceiver CBO J4859C-LEG 1250 Mbit/s 1310 nm is a compact single‑mode SFP module designed to provide reliable mid‑range fiber connections. It supports a data rate of 1250 Mbit/s and operates at a 1310 nm wavelength, making it suitable for standard serial optical links. The module is compatible with networking equipment that accepts SFP form‑factor modules and offers hot‑pluggable installation for minimal service disruption.

Advantages

This BlueOptics SFP transceiver delivers straightforward deployment with hot‑swappable operation and industry‑standard SFP compatibility. Its single‑mode optics and 1310 nm wavelength provide stable transmission over intermediate distances while maintaining low power consumption. The module is built to meet common optical networking requirements, offering consistent performance in switches, routers and media converters that support SFP ports.

Suitable for

• Establishing single‑mode fiber links between network switches and routers
• Connecting media converters to extend copper networks over fiber
• Replacing or adding SFP ports in communications equipment for mid‑range links

Key specifications

• Form factor: SFP (Small Form‑Factor Pluggable)
• Optical mode: Single‑mode fiber
• Wavelength: 1310 nm
• Data rate: 1250 Mbit/s
• Interface: LC duplex optical connector
• Hot‑pluggable: Yes

How to use

Insert the SFP transceiver into an empty SFP slot on the network device while the device is powered on or during maintenance windows, following the vendor’s hot‑swap guidelines. Connect a single‑mode LC duplex fiber patch cable to the module’s optical port, ensuring correct transmit/receive orientation. Verify link status on the host device and configure interface settings (speed, duplex, and optical diagnostics) as required by the network equipment.

Recommendations

Use quality single‑mode LC duplex cables and maintain clean fiber connectors to ensure optimal signal transmission. Confirm compatibility with the host device’s SFP specifications before deployment and monitor optical power and link LEDs after installation to validate correct operation.
