Fiber Optic Transceiver CBO ALL4755 — 1000Base-SX, 850 nm

CBO ALL4755 — 1000Base-SX, 850 nm is a fiber optic transceiver module designed for short-range Gigabit Ethernet links over multimode fiber. The module follows the standard SFP form factor and supports 1000Base-SX operation at a wavelength of 850 nm, enabling reliable high-speed connectivity between switches, servers and other network devices in data centers, server rooms and campus networks. The transceiver is intended for straightforward installation to extend or replace existing fiber connections while maintaining industry-standard compatibility.

Advantages

The module provides Gigabit throughput with low latency for short-distance multimode fiber runs and adheres to the SFP size and electrical interface standard for broad compatibility with networking equipment. Operating at 850 nm, it is optimized for multimode fiber links and simplifies upgrades or replacements by fitting into standard SFP ports. The compact design reduces space requirements in dense rack deployments and allows hot-swappable installation without powering down connected devices.

Suitable for

• Short-range Gigabit Ethernet connections over multimode fiber
• Inter-switch links within data centers and server rooms
• Upgrading or replacing fiber ports on switches and routers
• Connecting servers, storage arrays and chassis in enterprise networks

Key specifications

• Standard: 1000Base-SX (Gigabit Ethernet)
• Optical wavelength: 850 nm
• Form factor: SFP (Small Form-factor Pluggable)
• Fiber type: Multimode fiber (MMF)
• Typical reach: short-range links (multimode reach dependent on fiber type and modal bandwidth)
• Connector type: LC duplex compatible
• Hot-pluggable: yes

How to use

Insert the transceiver into an empty SFP port on a compatible switch, router or network device until it seats securely. Connect LC duplex multimode fiber patch cords to the transceiver ports, ensuring correct transmit/receive orientation. Configure the link settings on both ends of the connection according to your network equipment management interface; most devices will negotiate Gigabit speed automatically with standard 1000Base-SX modules. Verify link status and diagnostics through the host device to confirm successful operation.

Recommendations

Use multimode fiber cabling with appropriate modal bandwidth rating for the desired distance and avoid bending or stretching fiber patch cords. When replacing or adding transceivers, confirm compatibility with the host device and update device firmware if required. For optimal performance in data centers, plan fiber routes to minimize connection loss and check link diagnostics periodically to detect degradation early.
