Fiber optic transceiver CBO iSFP-GIG-LH70 for 70 km single-mode links

The Fiber optic transceiver CBO iSFP-GIG-LH70 for 70 km single-mode links is a compact SFP module designed for gigabit fiber connections over long distances. Compatible with Alcatel Lucent equipment and other systems supporting standard SFP optics, this transceiver enables reliable data transfer for metro networks, ISPs and enterprise backhaul environments. The module supports single-mode fiber and is intended for links up to 70 km, offering a balance of reach and compact form factor for rack, chassis and small-form network devices.

Advantages

This BlueOptics transceiver provides long-reach single-mode connectivity in an SFP form factor, allowing straightforward hot-swap replacement and easy integration into existing fiber infrastructures. It is engineered for stable gigabit throughput with low-latency transmission across extended distances. Compatibility with Alcatel Lucent platforms simplifies deployment in mixed-vendor environments, while the compact design reduces space requirements in populated equipment racks.

Suitable for

• Metro aggregation links requiring 70 km reach
• Internet service provider backbone and access connections
• Enterprise WAN and campus backhaul between sites
• Network equipment upgrades and mixed-vendor optical deployment

Key specifications

• Form factor: SFP (small form-factor pluggable)
• Data rate: 1 Gbit/s (gigabit Ethernet/SDH/SONET compatible)
• Fiber type: single-mode
• Maximum link distance: up to 70 km over single-mode fiber
• Wavelength: long-haul optics suitable for extended reach (typical single-mode wavelength band)
• Connector type: standard LC duplex
• Hot-swappable: yes, supports in-service insertion and removal

How to use

Install the CBO iSFP-GIG-LH70 transceiver into a compatible SFP slot on your network device following the device manufacturer’s guidance. Connect single-mode fiber using LC duplex connectors, ensuring proper polarity and clean end faces to avoid signal loss. Verify link parameters and device registers after insertion; the module supports hot-swap so it can be replaced without powering down systems when supported by the host. Monitor link status through the host equipment’s management interface to confirm stable gigabit connectivity.

Recommendations

For optimal performance, use ITU-T-compliant single-mode fiber with appropriate attenuation budgets for 70 km span, maintain clean connector end faces, and verify optical power margins with a power meter or OTDR where possible. Ensure the host equipment firmware supports third-party SFP optics to avoid compatibility warnings.
