Fiber Optic Transceiver CBO MiniGBIC-LH-70, single‑mode 70 km

CBO MiniGBIC-LH-70 is a fiber optic transceiver module designed for single‑mode links with a specified reach of up to 70 km. Compatible with network equipment that supports the MiniGBIC/SFP form factor, this module provides long‑distance data transmission appropriate for backbone, metro and point‑to‑point fiber connections. The transceiver supports standard single‑mode interfaces and is intended for installation in optical ports to replace or upgrade existing modules while maintaining interoperability with common networking hardware.

Advantages

The MiniGBIC-LH-70 offers extended reach for single‑mode fiber applications, enabling connections over distances up to 70 km without intermediate repeaters. Its compact SFP/MiniGBIC form factor allows installation in a broad range of switches and routers that accept SFP modules, saving rack space and simplifying upgrades. The module is engineered for consistent optical performance and stable link operation, which supports reliable data transmission for critical network segments.

How to use

Install the MiniGBIC-LH-70 into an empty SFP slot on a compatible switch, router or media converter, ensuring correct orientation and seating until the module latches. Connect a single‑mode duplex fiber cable to the module's optical connector, observing transmit/receive pairing. After powering the host device, verify link status via the device management interface or status LEDs; allow the equipment to negotiate link parameters automatically. For replacement, remove the existing module by unlatching and pulling it straight out before inserting the new transceiver.

Recommendations

Use quality single‑mode fiber and LC duplex connectors to achieve the specified 70 km reach. Check host device compatibility with MiniGBIC/SFP modules and follow manufacturer guidance for supported transceiver models. Maintain clean fiber endfaces and employ suitable transceiver handling procedures to avoid contamination or damage to optical components.
