Transceptor de fibra ótica SFP CBO J4858DCM 1250 Mbit/s 850 nm

The SFP fiber optic transceiver CBO J4858DCM 1250 Mbit/s 850 nm is a compact, hot-pluggable module designed for short-range multimode fiber links. It supports a 1.25 Gbit/s data rate over 850 nm wavelength, providing optical connectivity for switches, routers and media converters in server rooms, access nodes and enterprise LAN environments. The module fits standard SFP slots and is intended to simplify the addition of optical ports where short-reach multimode connections are required.

Advantages

This SFP transceiver offers a small form factor and hot-pluggable operation for quick installation and replacement without powering down equipment. With support for 1250 Mbit/s at 850 nm it is optimized for short-range multimode fiber links, delivering reliable 1.25 Gbps connectivity. Compatibility with standard SFP interfaces ensures broad interoperability with networking equipment that accepts SFP optical modules.

Suitable for

• Short-range multimode fiber connections in data centers and server rooms
• Upgrading copper ports to 1.25 Gbps optical links on switches and routers
• Interconnection between access switches and media converters
• Enterprise LAN segments requiring optical uplinks over multimode cable

Key specifications

• Optical wavelength: 850 nm
• Data rate: 1.25 Gbit/s (1250 Mbit/s)
• Form factor: SFP (small form-factor pluggable)
• Fiber type: Multimode fiber (short-range applications)
• Connector type: LC duplex (common for SFP multimode transceivers)
• Hot-pluggable: Yes

How to use

Insert the transceiver into a compatible SFP slot on the switch, router or media converter until it latches. Connect multimode fiber with the appropriate LC duplex patch cord, ensuring correct transmit/receive alignment. Verify link status via the host device LEDs or management interface and ensure transceiver and fiber specifications match the intended connection distance and type. To remove, depress the latch and pull the module straight out without twisting.

Recommendations

Use multimode OM1/OM2/OM3 fiber that matches the required reach for 850 nm operation and avoid bending fibers beyond their minimum bend radius. Keep optical connectors clean and use dust caps when the module is not in use. Confirm SFP slot compatibility with the host device and check link parameters after installation for stable operation.
