Specifications

Rack Integration and Service Access

Plan the fiber route before removing connector protection. The patch lead should follow its manager without pulling on the transceiver, while leaving space to release the latch and service adjacent ports. Protect the end face until final connection and avoid tight bends immediately behind warm exhaust air. For this model, the principal parameters are data rate 42Gbps (4x 10.5Gbps), wavelength 850nm, rated reach 400m on OM4.

Applications and Optical Link Design

Typical deployments include switch-to-switch, switch-to-server and aggregation links inside a data hall or between adjacent equipment rooms. The MTP/MPO-12 Male interface connects to the specified multimode cabling, and the stated reach depends on fiber grade and link loss. Keep this interface on the matching multimode optical standard rather than connecting it directly to a single-mode wavelength or reach variant.

Before deployment, check the host port type, supported data rate and firmware requirements. The 10G interface configuration must match the remote equipment; sharing a QSFP+ housing alone does not make two transceiver types interoperable.

The multimode channel should use the fiber grade associated with the stated 400m on OM4 reach. Keep the MTP/MPO-12 Male end faces clean and avoid tight bends. Different multimode standards are not interchangeable merely because they share a connector.

Optical Acceptance, Diagnostics and Handling

For this model, the specified transmit-power range is -7.5~0dBm; receiver sensitivity is <-9.9dBm; the stated optical power budget is 2.4dB. Digital diagnostics make later maintenance easier when baseline values are captured at installation. Save the initial readings with the port and OEM reference, then investigate meaningful changes rather than reacting to a single transient value. Diagnostic support depends on the host as well as the module, so unavailable fields should be confirmed with the platform documentation. Before every insertion, keep dust caps in place until the patch lead is ready, avoid touching the optical end face and use an appropriate inspection and cleaning procedure. Do not look into an active optical interface.

Quality Assurance and Packaging

Before packing, the module receives interface inspection, identification and link checks. Protective packaging avoids pressure on the connector and latch. Customer references, rack groups and project packing lists can be added for volume orders.

Juniper Networks Compatibility and Factory Testing

The module is checked for host recognition as QSFPP-4X10GE-SR, link establishment and diagnostic reporting. Physical cage fit alone is not treated as evidence of compatibility. Equipment model, hardware revision and software release can be reviewed before dispatch where platform behavior is uncertain.

Frequently Asked Questions

Ordering Information

When ordering, specify QSFPP-4X10GE-SR, QSFP-CSR4-40G, quantity and intended host platform. Project labels can repeat these details for receiving and asset records. Neutral labels, customer packaging and project-specific compatibility review are available on request.

Shipping and Lead Time

Standard configurations normally ship within one to three working days, with production lead times confirmed for larger quantities. International courier, air freight and sea freight are available; customer courier accounts and nominated forwarders are accepted.
