Cisco compatible Q28-100GP4-BXU2931-20-C Description
EdgeOptic's Q28-100GP4-BXU2931-20-C compatible is a Cisco-coded version of the EdgeOptic BIDI-100G-Q28-SL20A multi-vendor 100G BiDi QSFP28 LR1 20km transceiver. It carries Cisco-recognized EEPROM programming for platform recognition, not a Cisco part number. No native Cisco ordering code exists for this single-lambda BiDi 20km class, so this SKU follows the market-standard Cisco-compatible naming pattern for that reach class.
The 20km single-fiber reach class follows the 100G Lambda MSA 100G-LR1-20 naming convention, not an IEEE-defined PMD; IEEE 802.3cu Clause 140 100GBASE-LR1 is a separate duplex 1310nm specification for 10km and above. This single-lambda PAM4 BiDi design is also non-interoperable with 100GBASE-BX20, the 4-lane NRZ BiDi optic used on some Cisco and Arista platforms.
This Side A module carries a 1291nm transmit wavelength and a 1311nm receive window, and pairs with the Side B module Q28-100GP4-BXD3129-20-C, not with another Side A unit. Its 20nm receive wave bandwidth is wide enough that the partner module's transmit wavelength falls within the passband on each end of the link. Order one of each side per fiber run.
Data rate and application scope are fixed at 106.25 Gbps PAM4 for 100G Ethernet only, with no Fibre Channel or OTN framing support. The transmitter is an EML laser paired with a PIN photodiode receiver, and FEC is integrated in the DSP. Operating temperature is rated 0 to 70 degrees Celsius, with a maximum power draw of 4.5W.
EdgeOptic backs this module with a lifetime warranty. Verify the target Cisco platform's transceiver support documentation before deployment, since third-party optic recognition can vary by hardware and software release. For volume pricing or an alternate vendor coding, contact our sales team.
Frequently Asked Questions
Will my Cisco switch or router recognize this module, or flag it as unsupported?
The Q28-100GP4-BXU2931-20-C is EEPROM-coded for Cisco platform recognition. Exact behavior, including whether a given platform accepts, warns on, or blocks a third-party optic, depends on the specific hardware model and software release. Verify against the target platform's transceiver support documentation before deployment.
Is Q28-100GP4-BXU2931-20-C an actual Cisco part number?
No. Cisco does not publish a native ordering code for this single-lambda BiDi 20km optic class. Q28-100GP4-BXU2931-20-C follows the market-standard Cisco-compatible SKU pattern used across the industry for this reach class. Cisco's own single-lambda 100G optics belong to the duplex 100GBASE-LR1 product line defined in IEEE 802.3cu Clause 140, a different design from this single-fiber BiDi module.
Ordering for a Cisco-to-Cisco link, do I need the Side B module too?
Yes. This SKU is the Side A module, coded with a 1291nm transmit wavelength and a 1311nm receive window. Order one Q28-100GP4-BXU2931-20-C for one end of the link and one Q28-100GP4-BXD3129-20-C Side B module for the other end. Two Side A modules will not establish a link.
