Optic.ca QSFP-100G-SR4-S-OC — 100G Cisco-compatible SR4 QSFP28 transceiver
The Optic.ca QSFP-100G-SR4-S-OC is a 100GBASE-SR4 QSFP28 optical transceiver engineered for full compatibility with Cisco® equipment. Designed for high-density, short-reach 100G deployments in data centers, campus networks, and enterprise core/distribution layers, it operates over OM3 or OM4/OM5 multimode fiber using a 12-fiber MPO-12 UPC male connector. The module supports 4×25G breakout mode for interoperability with 25GBASE-SR links. Every Optic.ca transceiver is custom-coded in-house and rigorously tested to deliver OEM-level reliability — backed by a lifetime warranty and meeting or exceeding Tier 1 MTBF standards.
Guaranteed Cisco Compatibility, In-House Coded
Optic.ca custom-codes every transceiver in-house specifically for the target vendor platform — in this case, Cisco® switches, routers, and NICs. Unlike generic third-party optics that rely on generic firmware, each Optic.ca module is programmed to pass the host device's vendor ID check, eliminating 'unsupported transceiver' warnings and the need for manual overrides. For Cisco installations in production networks, this means the module behaves identically to the OEM part at a significantly lower cost — without voiding equipment warranty or requiring CLI workarounds at installation time.
4×25G Breakout Mode for Infrastructure Flexibility
The QSFP-100G-SR4-S-OC supports 4×25G breakout operation, splitting the single 100G link into four independent 25GBASE-SR channels. This makes it straightforward to connect a 100G switch port directly to four 25G server NICs using a standard MPO-to-4×LC breakout cable — a topology common in top-of-rack data center designs. Breakout capability means one port can serve four endpoints, reducing switch port count requirements and allowing gradual infrastructure scaling without replacing existing 25G server hardware.
Built-in DDM for Proactive Link Monitoring
Digital Diagnostic Monitoring (DDM) is embedded in the transceiver and accessible via the host device's management interface. It exposes real-time readings for optical transmit power, receive power, temperature, laser bias current, and supply voltage — all without additional hardware. For network operations teams, this means early warning of signal degradation or thermal stress before a link fails, greatly reducing mean time to diagnose (MTTD) on fiber faults and enabling proactive maintenance rather than reactive troubleshooting after an outage.
Lifetime Warranty and Tier 1 MTBF Reliability
Optic.ca backs the QSFP-100G-SR4-S-OC with a lifetime warranty and manufactures to Tier 1 MTBF standards — the same reliability benchmark used to qualify first-tier OEM optics. For network operators running 24/7 production infrastructure, this combination of build quality and warranty coverage significantly reduces total cost of ownership: failed units are replaced without additional cost, and the long mean-time-between-failures means fewer unplanned outages. The module also meets IEEE 802.3bm, QSFP28 MSA (SFF-8636), and CAUI-4 standards, ensuring broad interoperability.
