Description

The QSFP-100G-LR4-S-BCC is a drop-in compatible replacement for the Cisco QSFP-100G-LR4-S. This QSFP28 transceiver provides plug-and-play operation in Cisco switches and routers with 100G QSFP28 ports. - IEEE 802.3ba 100GBASE-LR4 compliance ensures interoperability with standards-compliant equipment and guarantees 10km reach over G.652 single-mode fibre - Four LAN WDM wavelengths (1295.56nm, 1300.05nm, 1304.58nm, 1309.14nm) multiplexed over duplex LC connectors, each lane carrying 25Gbps using NRZ modulation - Digital Diagnostic Monitoring (DOM) provides real-time access to optical power, temperature, bias current, and supply voltage via I2C interface - Hot-swappable QSFP28 form factor compliant with MSA SFF-8665 and SFF-8636 specifications - Commercial temperature range (0 to 70°C) suitable for data centre and enterprise network deployments - Cooled LAN WDM EA-DFB transmitters and high-sensitivity PIN receivers deliver reliable performance at up to 103.125 Gbps aggregate data rate

Features

• IEEE 802.3ba 100GBASE-LR4 compliance guarantees interoperability with standards-compliant switches, routers, and transceivers from any vendor, eliminating vendor lock-in for 10km single-mode links
• Four-lane LAN WDM architecture at 1295.56nm, 1300.05nm, 1304.58nm, and 1309.14nm multiplexes 25Gbps NRZ signals into a single duplex fibre pair, maximising port density without requiring parallel fibre infrastructure
• Cooled electro-absorption modulated DFB laser transmitters paired with high-sensitivity PIN photodiode receivers maintain optical link budget of 6.6dB minimum, ensuring margin for patch panel loss and fibre ageing
• Hot-swappable QSFP28 MSA form factor allows field installation and replacement without powering down the host platform, supporting zero-downtime maintenance procedures
• DDM functionality exposes transmit/receive optical power, module temperature, laser bias current, and supply voltage in real time, enabling proactive link health monitoring and troubleshooting without external test equipment
• Commercial temperature range (0 to 70°C) suits controlled data centre and enterprise network environments; does not employ FEC, relying on raw BER performance per IEEE 802.3ba specification
• Duplex LC/UPC connector interface compatible with existing G.652 single-mode fibre cabling plants deployed for 10G and 40G networks, enabling in-place migration to 100G without re-cabling

FAQs

Q: Will this work in place of the Cisco QSFP-100G-LR4-S?
A: Yes. The QSFP-100G-LR4-S-BCC matches the Cisco QSFP-100G-LR4-S in form factor (QSFP28), data rate (100Gbps), standard (IEEE 802.3ba 100GBASE-LR4), wavelengths (LAN WDM 1295-1309nm), and reach (10km over single-mode fibre). It is plug-and-play compatible and will initialise identically in Cisco equipment.

Q: Which Cisco platforms support this transceiver?
A: This module works in any Cisco switch or router with QSFP28 ports that support 100GBASE-LR4. Compatibility depends on the port supporting 100G Ethernet over four 25Gbps lanes with LAN WDM optics and duplex single-mode fibre. Consult the Cisco 100 Gigabit Ethernet Transceiver Modules Compatibility Matrix for your specific platform model and software release.

Q: What fibre type and patch cord specifications are required for 10km reach?
A: This transceiver requires G.652 standard single-mode fibre (9/125µm core/cladding diameter) with duplex LC/UPC connectors. The module provides a minimum 6.6dB optical link budget. To achieve 10km, total link loss (fibre attenuation plus connector and splice losses) must remain below this budget. Typical G.652 fibre attenuation is 0.35dB/km at 1310nm, allowing margin for connectors and ageing.

Q: Does this module require Forward Error Correction (FEC) on the host platform?
A: No. The IEEE 802.3ba 100GBASE-LR4 specification does not employ FEC, and this transceiver is designed to meet the required bit error rate (BER) without host-side FEC enabled. The four LAN WDM lanes use NRZ modulation at 25.78Gbps per lane, relying on the cooled EA-DFB laser and high-sensitivity PIN receiver to maintain link integrity over 10km without error correction.

Q: Can this transceiver interoperate with other vendors' 100GBASE-LR4 modules or different 100G form factors?
A: Yes, provided the opposing transceiver complies with IEEE 802.3ba 100GBASE-LR4 and uses the same LAN WDM wavelengths (1295.56nm, 1300.05nm, 1304.58nm, 1309.14nm). This module will interoperate with CFP, CFP2, CFP4, and CPAK 100GBASE-LR4 modules from any vendor as long as the Tx/Rx wavelengths align and both ends use duplex single-mode fibre. It does not work in QSFP+ (40G-only) ports.
