Network transceiver module CBO JNP-QSFP-40GE-IR4-BO 40,000 Mbit/s QSFP fiber optic

CBO JNP-QSFP-40GE-IR4-BO is a QSFP form-factor network transceiver module engineered for 40,000 Mbit/s (40GbE) fiber optic links. The module fits QSFP ports on switches, routers and server NICs to provide short- to medium-range optical transmission over multimode or singlemode fiber, enabling high-density switching and aggregation in data center, campus and enterprise backbone environments.

Advantages

This QSFP transceiver delivers 40 Gbit/s aggregate bandwidth in a compact, hot-pluggable QSFP package, reducing port density and cabling complexity. It supports standardized optical interfaces for interoperability with QSFP-enabled network equipment and is suitable for consolidated uplinks and spine-leaf interconnects. The module’s optical range and form factor allow flexible deployment for short- to medium-distance fiber runs while maintaining stable signal integrity and low-latency connectivity.

Suitable for

• Data center top-of-rack and spine links
• Server uplinks and switch aggregation ports
• Campus backbone and building-to-building fiber connections
• High-density switch deployments requiring 40GbE

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 40,000 Mbit/s (40GbE)
• Transmission: Fiber optic
• Optical reach: short- to medium-range multimode or singlemode links (dependent on fiber type and transceiver variant)
• Connector type: QSFP-compatible fiber interface
• Hot-pluggable: yes

How to use

Install the QSFP transceiver into a compatible QSFP port on your switch, router or NIC while the host device is powered according to the equipment manufacturer’s hot-plug guidelines. Connect appropriate fiber optic cables and ensure correct polarity and connector type. Verify link status via the host device’s management interface and confirm negotiated speed of 40GbE. For new installations, plan fiber routes and patching to maintain bend radius and minimize insertion loss.

Usage recommendations

Use this module with compatible QSFP ports and certified fiber cabling. Match the transceiver’s optical type to your fiber (multimode or singlemode) and select suitable patchcords and transceivers for the distance required. Monitor link parameters after installation and follow equipment vendor guidance for firmware and compatibility lists to ensure reliable 40GbE operation.
