Optical SFP transceiver CBO JD494A-BO 1.25G 850nm for short-range multimode fiber

CBO JD494A-BO is a compact SFP optical transceiver module that supports a 1.25G data rate and operates at an 850 nm wavelength for short-range multimode fiber links. Designed for use in switches, routers and other network equipment compatible with H3C and HPE platforms, this hot-pluggable module enables straightforward integration into existing Ethernet infrastructures. Its form factor and signal characteristics make it suitable for data center uplinks, server connections and campus network segments that require reliable short-distance optical connectivity.

Advantages

The module delivers stable 1.25G performance over multimode fiber with 850 nm VCSEL-based optics optimized for short-range transmission. Hot-pluggable design simplifies replacement and upgrades without powering down equipment. Compact SFP form factor ensures compatibility with a wide range of switches and routers, while proven interoperability with H3C and HPE-compatible systems reduces integration effort. The transceiver offers a balance of density, link reliability and predictable optical behavior for typical enterprise and data center environments.

Suitable for

• Short-range multimode fiber links in data centers
• Server-to-switch connections and top-of-rack uplinks
• Campus LAN segments and building-to-building links over MMF
• Switch and router ports on H3C- and HPE-compatible equipment

Key specifications

• Optical interface: 850 nm wavelength for multimode fiber
• Data rate: 1.25 Gbit/s
• Form factor: SFP (small form-factor pluggable)
• Transmission type: short-range (multimode fiber)
• Connector type: standard SFP duplex LC-compatible interface
• Hot-pluggable capability for live insertion and removal

How to use

Insert the SFP module into a compatible SFP port on the switch or router until it clicks into place. Connect multimode fiber patch cords with the appropriate duplex LC connectors to the transceiver. Ensure the networking equipment is configured for 1.25G operation and verify link status via device LEDs or management interfaces. For removal, power down the affected interface if required by your operations policy, press the release latch and gently withdraw the transceiver. Follow standard ESD precautions when handling the module and keep optical ports capped when not in use to prevent contamination.

Usage recommendations

Use OM1/OM2/OM3 multimode fiber consistent with the required link distance and loss budget; verify polarity and connector cleanliness before deployment. Match the transceiver settings on both ends of the link for speed and duplex, and monitor link metrics after installation to confirm stable operation.
