Product information

Description

The BlueOptics Fiber optic transceiver CBO J4858B-BO 1000 Mbit/s 850 nm is a compact SFP-style module engineered for short-range Gigabit Ethernet over multimode fiber. It supports 1000 Mbit/s data throughput at an 850 nm wavelength, delivering stable links between switches, routers and media converters. The module is intended to extend network reach within data centers, enterprise LANs and campus environments where reliable multimode fiber connections are required.

Advantages

This transceiver offers a standardized SFP form factor for broad compatibility with networking equipment that accepts hot-swappable fiber modules. Operating at 850 nm, it is optimized for short-range multimode fiber runs and provides a balance of performance and compact size. Its 1000 Mbit/s capability ensures compatibility with Gigabit Ethernet networks, and the module’s design supports straightforward installation and maintenance without disrupting active systems.

Suitable for

Short-range Gigabit Ethernet links over multimode fiber
Interconnecting switches and routers within racks or across adjacent rooms
Extending connectivity to media converters and fiber-enabled network appliances
Data center and enterprise LAN uplinks on multimode fiber plants

Key specifications

Data rate: 1000 Mbit/s (Gigabit Ethernet)
Optical wavelength: 850 nm
Form factor: SFP (small form-factor pluggable) module
Fiber type: Multimode fiber compatibility
Typical reach: short-range multimode links (dependent on fiber grade and network conditions)
Connector interface: standard duplex fiber connector (LC-style compatible)

How to use

Install the transceiver into an available SFP slot on your switch, router or media converter with the network device powered according to the vendor’s hot-swap guidance. Connect multimode fiber cables using the appropriate duplex connector, ensuring correct alignment and cleanliness of fiber endfaces to minimize signal loss. After physical installation, verify link status via the device’s management interface and confirm negotiated speed at 1000 Mbit/s. For troubleshooting, inspect fiber connectors for contamination and check device logs for link events.

Usage recommendations

Use high-quality multimode fiber (OM1/OM2/OM3/OM4 as appropriate) and maintain clean connector endfaces. Keep maximum cable lengths within recommended short-range limits for 850 nm links and consult equipment vendor compatibility lists when integrating SFP modules into existing systems.
