Juniper QSFP-100GBASE-SR4 Compatible 100GBASE-SR4 QSFP28 Transceiver

EdgeOptic's QSFP-100GBASE-SR4 compatible is a Juniper-coded 100GBASE-SR4 version of the EdgeOptic 100G-QSFP28-100 multi-vendor 100GBASE-SR4 transceiver, one universal short-reach module coded for a range of switch and router vendors. It runs 100G Ethernet over four parallel 850 nm VCSEL lanes at 25G each across multimode fiber, terminated on an MTP/MPO-12 (UPC) connector using 8 active fibers, 4 transmit and 4 receive. The transceiver port is female (unpinned); the patch cable is the pinned male side, so transceiver-to-transceiver runs need a male-to-male Type B MPO assembly. Reach is 70 m over OM3 and 100 m over OM4, per IEEE 802.3bm Clause 95.

Optical specifications include a 1.9 dB average link budget, receiver sensitivity of −10.3 dBm per lane, NRZ modulation, and no FEC at this reach. The transmitter uses 850 nm VCSEL lasers; the receiver is a PIN photodiode. OM4 supports the full 100 m while OM3 is rated to 70 m, with achievable distance depending on patch panels, splices, and connector cleanliness in the installed link. DDM/DOM is supported per SFF-8636, so the host can read per-lane transmit power, receive power, and bias along with module-level temperature and voltage. The module operates across the 0°C to 70°C commercial range, draws up to 3.5 W within the QSFP28 envelope, and is compliant with the QSFP28 MSA and SFF-8665. This is an Ethernet-only 100G short-reach optic; it does not carry Fibre Channel, OTN, or SONET traffic.

Juniper lists QSFP-100GBASE-SR4 under part number 740-058734 in the Hardware Compatibility Tool, a distinct catalog entry from the 740-061405 SR4 modules, with QSFP-100G-SR4-C noted as a Common Optic Equivalent. EdgeOptic codes this compatible with Juniper-recognized EEPROM so the host reads it as a supported transceiver. It works across the Juniper switching and routing platform family; confirm the specific platform against the Juniper Hardware Compatibility Tool before deployment, since the 100G QSFP28 port can be split to four 25GBASE-SR channels on hosts that support breakout. Typical roles include data center core interconnects and provider edge aggregation.
