Transceptor SFP de fibra ótica CBO TN-SFP-LXB21-BO 1250 Mbit/s 1550 nm

CBO TN-SFP-LXB21-BO is an SFP fiber transceiver module designed for single-mode optical links. It supports a serial data rate of 1250 Mbit/s and transmits at a wavelength of 1550 nm, providing a compact hot-pluggable interface to connect switches, routers and other optical networking equipment over fiber. The module is intended for point-to-point transmission on single-mode fiber and offers a standard SFP form factor for easy installation in compatible SFP ports.

Advantages

The SFP form factor offers hot-pluggable convenience and wide compatibility with network devices that accept standard SFP transceivers. Operation at 1550 nm enables longer reach on single-mode fiber when compared to shorter wavelengths, and the 1250 Mbit/s serial data rate aligns with common Gigabit Ethernet and fiber channel applications that require reliable serial optical links. The module’s compact size reduces space requirements and simplifies upgrades or replacements in existing infrastructure.

Suitable for

• Extending network links between switches and routers over single-mode fiber
• Interconnecting optical equipment in enterprise or carrier networks
• Point-to-point long-reach fiber connections where 1550 nm operation is required
• Replacing or upgrading SFP ports in servers, media converters and optical transceivers

Key specifications

• Interface: SFP hot-pluggable module (standard SFP form factor)
• Data rate: 1250 Mbit/s serial optical transmission
• Wavelength: 1550 nm suitable for single-mode fiber
• Fiber type: single-mode fiber (SMF)
• Application: point-to-point optical links and standard network transceiver use

How to use

Install the module into an available SFP port on a compatible switch, router or optical device while the host port is powered down or following the device manufacturer’s hot-plug guidelines. Use an appropriate single-mode fiber patch cable with matching connectors to connect the transmit and receive ports between devices. Observe correct fiber polarity and ensure connectors are clean before mating. Configure the host device’s interface settings as required by the network topology and verify link status through the device management interface or LEDs.

Recommendations

To ensure reliable operation, use single-mode fiber rated for the expected reach at 1550 nm, keep optical connectors clean and avoid excessive bend radii. Verify compatibility with the host device’s supported SFP modules and check firmware or configuration settings if the link does not come up immediately.
