Description

The QSFP-40G-SR4-S-BCC is a drop-in compatible replacement for the Cisco QSFP-40G-SR4-S. This S-Class enterprise transceiver delivers plug-and-play 40 Gigabit Ethernet connectivity over multi-mode fibre using 12-fibre MPO/MTP parallel optics. - IEEE 802.3ba 40GBASE-SR4 compliance guarantees interoperability with all standard 40GBASE-SR4 interfaces - QSFP+ form factor supporting 40Gbps over four 10Gbps lanes at 850nm wavelength via VCSEL array - 100m reach on OM3 multi-mode fibre, 150m on OM4 or OM5 laser-optimized multi-mode fibre - MPO/MTP 12-fibre female connector interface for parallel fibre ribbon cable - Digital diagnostics monitoring (DDM) support for real-time optical parameter tracking - Does not support 4x10G breakout mode or FCoE (Fibre Channel over Ethernet) applications

Features

• IEEE 802.3ba 40GBASE-SR4 compliance ensures full interoperability with all standards-compliant 40G short-reach interfaces, eliminating compatibility risk with vendor equipment or third-party optics in the same link.
• Four independent parallel lanes, each operating at 10.3125 Gbps using 850nm VCSEL laser technology, aggregate to 40Gbps throughput without requiring lane bonding or FEC configuration at the host.
• S-Class designation indicates this module is optimized for native 40G applications only and does not support 4x10G breakout connectivity or FCoE encapsulation, simplifying deployment in pure 40GbE environments.
• Hot-swappable QSFP+ form factor allows installation or removal during live operation without host reboot, and digital diagnostics provide per-lane monitoring of optical transmit/receive power, temperature, voltage, and bias current.
• 12-fibre MPO/MTP parallel ribbon interface delivers reach up to 150m on OM4 or OM5 fibre with lower loss budget requirements than duplex-based solutions, supporting high-density spine-leaf or intra-rack topologies.
• Low power dissipation under 1.5W typical enables high port-density deployment in chassis with limited thermal headroom, and commercial-grade 0-70°C operation suits enterprise data centre and campus core environments.

FAQs

Q: Will this work in place of the Cisco QSFP-40G-SR4-S?
A: Yes. This transceiver is aligned to IEEE 802.3ba 40GBASE-SR4 specifications and matches the QSFP-40G-SR4-S form factor, data rate, wavelength, and fibre interface. It is plug-and-play compatible with Cisco platforms that accept the QSFP-40G-SR4-S and operates identically in native 40G mode.

Q: Which Cisco platforms support this transceiver?
A: This module works in any Cisco switch, router, or NIC with a QSFP+ port that supports 40GBASE-SR4 optics, including Nexus data centre switches, ASR aggregation routers, and Catalyst enterprise platforms with 40G uplink slots. Consult your platform's optics compatibility matrix to confirm QSFP-40G-SR4-S support.

Q: Why does the S-Class variant not support 4x10G breakout mode?
A: The QSFP-40G-SR4-S transmit and receive optical power levels are optimized exclusively for IEEE 40GBASE-SR4 operation and may cause receiver overload or alarm threshold violations when connected to 10GBASE-SR interfaces via breakout cable. For 4x10G breakout applications, use the standard QSFP-40G-SR4 or QSFP-40G-CSR4 variants instead.

Q: What is the maximum supported distance on OM3 versus OM4 fibre?
A: The module supports up to 100 metres over OM3 multi-mode fibre and up to 150 metres over OM4 or OM5 laser-optimized multi-mode fibre. These distances assume compliant MPO connector insertion loss and proper fibre plant quality. OM4 and OM5 offer lower modal bandwidth dispersion at 850nm, enabling the longer reach.

Q: Does this transceiver require any host FEC or special configuration?
A: No. IEEE 40GBASE-SR4 over multi-mode fibre at 100-150m does not require forward error correction (FEC) for standards-compliant BER performance. The module operates as a physical layer device and requires no software configuration, NOS compatibility testing, or driver installation beyond ensuring the host port is set to 40G mode and auto-negotiation is enabled or disabled per your platform requirements.
