SFP-10G-LR-S-BCC | Cisco Compatible 10GBASE-LR SFP+ Module for SMF, S-Class (does not support FCoE)

Q: Will this work in place of the Cisco SFP-10G-LR-S?
A: Yes. The SFP-10G-LR-S-BCC is a direct plug-and-play replacement for the Cisco SFP-10G-LR-S, matching its SFP+ form factor, 10.3125 Gbps data rate, 1310nm wavelength, and 10km reach on G.652 single-mode fibre. It conforms to IEEE 802.3ae 10GBASE-LR and SFF-8431 electrical interface standards, ensuring compatibility with any Cisco switch or router that accepts the original part.

Q: Which Cisco platforms support this module?
A: This module works in any Cisco platform with SFP+ ports that support 10GBASE-LR optics. Compatibility is determined by the SFP+ port standard and the platform's support for 10 Gigabit Ethernet, not by specific model numbers. Consult the Cisco 10 Gigabit Ethernet Transceiver Modules Compatibility Matrix for your platform to confirm SFP-10G-LR-S support, or verify that your device has SFP+ ports rated for 10GbE operation.

Q: What type of fibre and minimum cabling distance does this require?
A: This module requires G.652 single-mode fibre (OS2) with dual LC connectors. The minimum cabling distance is 2 metres per IEEE 802.3ae specification to prevent receiver saturation. Use patch cords with PC or UPC polish only; APC connectors are not supported. The maximum reach is 10 kilometres on standard single-mode fibre, subject to fibre quality and total link budget.

Q: Why does the S-Class designation matter for my network?
A: The S-Class designation indicates this is a single-rate, Ethernet-only module that does not support FCoE (Fibre Channel over Ethernet), OTN (Optical Transport Network), or WAN-PHY protocols. If your network requires pure 10 Gigabit Ethernet connectivity without storage or transport overlays, S-Class modules offer cost-effective performance. If you need FCoE for converged storage and data traffic, or multirate operation for OTN/WAN-PHY, select a non-S-Class module instead.

Q: Can I access DOM parameters, and what do they tell me?
A: Yes. This module supports digital optical monitoring (DOM) per SFF-8472, accessible via the two-wire serial interface at I2C address A2h. You can monitor transceiver temperature, laser bias current, transmitted optical power, received optical power, and supply voltage in real time. The module also provides alarm and warning flags that trigger when parameters exceed factory-set thresholds, enabling proactive troubleshooting of link degradation before traffic is affected.
