CBO optický transceiver 61556-BO LC Singlemode 1250 Mbit/s 550 m

The CBO fiber optic transceiver 61556-BO LC single-mode 1250 Mbit/s 550 m is a compact optical module designed for single-mode network links. It supports a data rate of 1250 Mbit/s and an optical reach up to 550 metres over single-mode fiber with an LC connector interface. The transceiver is intended for use in devices that require a straightforward optical uplink or extension of a local network segment and fits into standard compatible transceiver slots.

Advantages

This module provides a reliable single-mode optical connection with an LC interface and a defined reach of up to 550 m, enabling predictable link planning. Its 1250 Mbit/s data rate supports standard gigabit-compatible network architectures that use 1.25 Gbit/s optical signalling. The compact form factor simplifies installation in switches, routers and fiber patch panels while reducing space usage in equipment racks.

Suitable for

• Optical uplinks between switches and routers within campus or building networks
• Extending a network segment where single-mode fiber is deployed
• Integration into fiber patch panels and media converters with LC ports

Key specifications

• Connector type: LC
• Fiber type: single-mode
• Data rate: 1250 Mbit/s (1.25 Gbit/s optical signalling)
• Maximum reach: up to 550 metres
• Form factor: compact transceiver module compatible with standard slots (check device compatibility)

How to use

Install the transceiver into a compatible device slot following the device manufacturer's procedure for hot-plugging or powered installation. Connect a single-mode LC fiber patch cable to the module, ensuring proper end-face cleanliness and correct polarity. Configure the network device as required for the optical port, verify link status and monitor for stable operation. Replace protective dust caps only when the module is not in use to protect the optical interfaces.

Recommendations

Observe standard fiber handling practices: keep connector end-faces clean, use appropriate dust caps, avoid tight bends in fiber cabling and verify compatibility with the host device. For link planning, account for cable attenuation and margins to ensure reliable operation at distances up to 550 m over single-mode fiber.
