Description

The Q28-100GSR4-BCC is a drop-in compatible replacement for the Dell Q28-100GSR4 transceiver. This QSFP28 module delivers plug-and-play 100GbE connectivity in Dell networking platforms requiring a 100GBASE-SR4 interface. - IEEE 802.3bm and QSFP28 MSA compliance guarantee interoperability across vendor platforms and assure performance across the full aggregate 100Gbps data rate - QSFP28 form factor, 850nm wavelength, 100m reach over OM4 multi-mode fibre, up to 70m over OM3 - Four independent full-duplex channels, each operating at 25.78Gbps, with MTP/MPO-12 connector for parallel optics - Digital diagnostic monitoring (DDM) provides real-time access to transceiver temperature, laser bias current, transmitted and received optical power, and supply voltage - Also available as Dell reference SKUs 407-BCEX and 407-BBWV for applications requiring alternate part number specification - Supports breakout to 4x 25GBASE-SR SFP28 modules via MPO to 4x LC duplex OM3/OM4 breakout cable

Features

• IEEE 802.3bm compliance guarantees 100GBASE-SR4 operation across MSA-compatible host equipment, while QSFP28 MSA and SFF-8636 adherence ensure electrical and mechanical interoperability with Dell switches and routers
• Parallel optics architecture with 4 independent transmit and receive channels delivers 25.78Gbps per lane using 850nm VCSEL array technology, achieving 103.125Gbps aggregate throughput over 12-fibre ribbon cable
• Hot-swappable design with single 3.3V power supply and maximum 3.5W consumption supports installation without service interruption, with 1.9 dB minimum optical link budget providing margin for typical data centre patching losses
• DDM functionality exposes transceiver temperature, individual lane optical power (transmit and receive), bias current, and supply voltage via I2C interface for proactive link health monitoring and troubleshooting
• Supports flexible deployment topologies including 100m direct connection over OM4 ribbon fibre or breakout to four independent 25GBASE-SR links using MPO-to-LC fanout, enabling top-of-rack to spine or server connectivity
• Operating range 0°C to 70°C suits controlled data centre environments with standard thermal management; MTP/MPO-12 connector requires polarity-managed cabling per TIA-568 type B or type A with appropriate adapters

FAQs

Q: Will this work in place of the Dell Q28-100GSR4?
A: Yes. The Q28-100GSR4-BCC is IEEE 802.3bm 100GBASE-SR4 and QSFP28 MSA compliant, matching the Dell Q28-100GSR4 in form factor, data rate, wavelength, and reach. It is plug-and-play compatible and will operate identically in Dell QSFP28 ports requiring a 100GBASE-SR4 interface. It is also compatible with Dell reference SKUs 407-BCEX and 407-BBWV.

Q: Which Dell platforms support this transceiver?
A: This module works in any Dell switch or router with a QSFP28 port that supports 100GBASE-SR4 operation. It is designed for standard Dell networking platforms requiring 100GbE multi-mode connectivity at 850nm over an MPO interface. If your Dell equipment accepts the Q28-100GSR4, 407-BCEX, or 407-BBWV OEM part, this module will function identically.

Q: What fibre type and reach does this transceiver support?
A: This module operates over OM3 or OM4 multi-mode fibre. Maximum reach is 70m over OM3 and 100m over OM4, based on the 1.9 dB minimum optical link budget specified in IEEE 802.3bm. Actual reach depends on fibre quality, patch panel insertion loss, and connector cleanliness. OM5 fibre will also support these distances, though it is not required for 850nm parallel optics.

Q: Can I use this module for breakout to 4x 25G links?
A: Yes. This QSFP28 SR4 module supports breakout to four independent 25GBASE-SR SFP28 links using an MPO-12 to 4x LC duplex breakout cable over OM3 or OM4 fibre. Each lane operates at 25.78Gbps and can connect to a 25GBASE-SR SFP28 module up to 70m (OM3) or 100m (OM4). Ensure your Dell platform supports QSFP28 port breakout configuration and that you manage polarity correctly for type B or type A fibre cabling.

Q: Does this transceiver require specific FEC settings or NOS configuration?
A: 100GBASE-SR4 over multi-mode fibre at 100m typically does not require forward error correction (FEC) due to the short reach and high link budget, but your Dell NOS may enable FEC by default. The module will operate with or without FEC as configured by the host. No special EEPROM programming or port configuration is needed beyond standard 100GBASE-SR4 mode selection. DDM parameters are accessible via standard I2C commands without additional software.
