Juniper QSFPP-4x10GE-LR Optical Transceiver Test Report

Time: 2024-11-25
        Juniper offers the QSFPP-4x10GE-LR optical transceiver, which supports 40G Ethernet transmission up to 10 km over standard single-mode fiber (SMF). Moduletek Laboratory conducted prototype testing on this product to help users better understand its performance specifications and real-world application effect.
1. Product Description
        The Juniper QSFPP-4x10GE-LR optical transceiver supports a 10 km transmission link over standard single-mode fiber (SMF) and adopts an MPO-12 APC connector. The official key parameters and physical appearance of the transceiver are shown below:

2. Transceiver On-Board Identification
        Insert the Juniper QSFPP-4x10GE-LR optical transceiver into a Juniper QFX5200-32C switch. The transceiver establishes a normal link, with the port indicator lit. The switch can recognize transceiver information normally, including transceiver type, vendor name, model number, serial number, operating rate, and transmission distance. DOM data is readable, all values are within the standard threshold, and no alarms are generated.
