SFP transceiver CBO SFP-1G-LH 1G 1310 nm single‑mode bi‑di module

The CBO SFP-1G-LH 1G 1310 nm single‑mode bi‑di module is an SFP optical transceiver designed for long‑reach 1 Gbps Ethernet links over single‑mode fiber. The transceiver fits standard SFP ports used in switches, routers and media converters and supports a 1310 nm wavelength in a bi‑directional configuration to enable fibre‑saving point‑to‑point connections. Its hot‑pluggable form factor allows straightforward insertion and replacement without powering down network devices.

Advantages

This BlueOptics SFP module provides reliable single‑mode transmission at 1 Gbps and 1310 nm, optimized for long‑distance uplinks and link aggregation. The bi‑di design reduces the number of fiber strands required for point‑to‑point links, which simplifies cabling and can lower infrastructure costs. Compact SFP form factor and hot‑swappability minimize downtime during maintenance and upgrades.

Suitable for

• Long‑reach Ethernet uplinks between switches and routers over single‑mode fiber
• Point‑to‑point fiber links where fiber count needs to be minimized
• Media converters and network appliances with SFP slots requiring 1 Gbps links
• Data centre edge connections and campus backbone segments

Key specifications

• Form factor: SFP (small form‑factor pluggable)
• Data rate: 1 Gbps (Gigabit Ethernet)
• Wavelength: 1310 nm
• Fiber type: single‑mode fiber
• Transmission type: bi‑directional (bi‑di) on a single fiber strand pair
• Interface: LC connector
• Hot‑pluggable: yes

How to use

Insert the SFP transceiver into an empty SFP port on a compatible switch, router or media converter until it seats firmly and any retention latch engages. Connect the single‑mode fiber using appropriate LC connectors, ensuring correct transmit/receive orientation according to the bi‑di pair. After insertion, verify link status on the network device and configure interface settings such as speed, duplex and auto‑negotiation if required by the host equipment. To remove, disengage the latch and pull the module straight out; handle the optical interfaces with dust caps on when disconnected to protect the optical surfaces.

Usage recommendations

Use this module with single‑mode fiber plant rated for long‑reach links and LC connectors. Ensure compatible SFP host devices and check device documentation for supported transceiver types. Keep unused optical ports covered with dust caps and avoid touching fiber endfaces. For best performance, monitor link status and use proper ESD precautions when handling the module.
