Transceiver CBO GSLC30-DDM vlákno 1000Base-SX 850nm

The Transceiver CBO GSLC30-DDM Fiber Optic 1000Base-SX 850nm is a single‑mode module engineered for Gigabit Ethernet over multimode fiber at an 850 nm wavelength. It supports 1000Base-SX links and integrates digital diagnostics monitoring (DDM) to deliver real‑time information on optical parameters such as transmit power, receive power, temperature and supply voltage. The module is intended for short‑reach fiber connections in networking equipment including switches, routers and servers where reliable multimode fibre connectivity is required.

Advantages

This transceiver offers plug‑and‑play compatibility with standard SFP ports and supports industry‑standard 1000Base‑SX signaling for straightforward integration into existing Ethernet infrastructure. The built‑in DDM enables active monitoring of optical link health, facilitating faster fault diagnosis and reduced downtime. Compact SFP form factor and low power consumption make it suitable for dense port environments and energy‑sensitive deployments.

Suitable for

• Short‑reach Gigabit Ethernet links over multimode fiber (MMF)
• Connections between switches, routers and servers within data centers and wiring closets
• Access and distribution layer links where 850 nm optics are standard
• Environments requiring ongoing optical parameter monitoring for maintenance

Key specifications

• Data rate: 1 Gbps (1000Base‑SX)
• Operating wavelength: 850 nm
• Form factor: SFP (Small Form‑factor Pluggable)
• Compatible fiber type: Multimode fiber (MMF)
• Diagnostic feature: Digital Diagnostics Monitoring (DDM) for Tx/Rx power, temperature and supply voltage
• Typical reach: short‑reach links over MMF (refer to multimode fiber grading for exact distances)
• Power consumption: low‑power SFP class device

How to use

Install the transceiver into an available SFP slot of a compatible switch, router or server network interface and secure it according to the host equipment instructions. Connect LC‑terminated multimode fiber patch cords to the transceiver ports, ensuring correct polarity. After insertion, verify link status on the host device and use the DDM readings via management interface or CLI to check transmit and receive power, temperature and voltage if required. To remove the module, power down or follow hot‑swap procedures recommended by the equipment vendor and pull the SFP module straight out by its extraction tab.

Recommendations

Use multimode fiber of appropriate grade (OM1/OM2/OM3/OM4) and quality patch cords with LC connectors for predictable link performance. Avoid exposing the optical interface to dust and contaminants; keep dust caps on until connection and inspect fiber endfaces before mating. Monitor DDM values periodically to detect degradation early and comply with host device hot‑swap guidance to prevent port or module damage.
