Hanwha SKY-SWSFP-001 Wisenet SFP MMF Optical Module
The Hanwha SKY-SWSFP-001 is a hot-swappable SFP optical transceiver module designed for Wisenet SKY Switches in fiber-based surveillance and enterprise network deployments. Operating at 850nm multi-mode fiber, it delivers 1.25Gbps throughput across 550 meters — enough range to span a multi-building campus without intermediate regeneration. This module is essential for integrators connecting distributed camera clusters, consolidating bandwidth from remote access-control systems, or isolating surveillance traffic on isolated fiber runs where EMI immunity matters.
Key Features
- SFP Form Factor: Hot-swappable module — insert and lock without power-down. Field-replaceable, no downtime to swap fiber types or upgrade.
- Multi-Mode Fiber (MMF) at 850nm: Standard wavelength for short-to-medium distances. Operates over standard OM3/OM4 duplex or simplex cabling.
- 1.25Gbps Data Rate: Supports simultaneous streaming from 8–16 2MP IP cameras or 4–8 5MP cameras per fiber pair, depending on codec and frame rate.
- 550-Meter Transmission Distance: No repeater or optical regeneration required — spans large industrial campuses, multi-building parking structures, and distributed perimeter installations.
- Wisenet SKY Switch Compatibility: Works exclusively with Hanwha SKY-series switches; ensures consistent driver support and SFP identification across the ecosystem.
- Passive Optical Design: No additional power draw beyond the host switch's SFP port — reduces UPS load and cooling overhead on switch infrastructure.
- Industrial Temperature Range: Rated for extended temperature operation in outdoor-mounted switch enclosures and unheated telecommunications huts.
The SKY-SWSFP-001 addresses a specific integration challenge: fiber-native surveillance networks. Many legacy and modern campuses have pre-existing single-mode or multi-mode fiber backbone infrastructure installed for data centers or telecom use. Rather than running separate copper PoE runs to every camera, integrators can tap that fiber infrastructure, consolidate multiple camera feeds onto a single fiber pair, and avoid the cost and complexity of media converters. At 550 meters, a single module can link a remote guard shack or storage facility back to a central NVR cluster without active regeneration — critical for fail-safe operation in environments where distributed power supplies are unreliable.
Deployment scenarios include perimeter surveillance in industrial complexes (where copper cabling may be vulnerable to EMI from high-voltage equipment), campus-wide camera consolidation (police departments, universities, utility substations), and sites with pre-installed fiber conduit. The 850nm MMF standard ensures compatibility with commodity off-the-shelf cabling and third-party SFP optics if future module replacement is needed — you are not locked into proprietary transceiver sourcing. Pair the SKY-SWSFP-001 with Wisenet SKY Switch PoE/PoE+ uplinks to deliver both power and video to remote camera locations over a single fiber run, reducing total installation labor and material cost versus running separate power and data cables.
Integration is transparent: the module appears to the Wisenet SKY Switch as a standard SFP port. ONVIF Profile S and Profile T compatibility across all attached IP cameras means your existing VMS (Genetec, Milestone, Avigilon) requires no reconfiguration — the fiber link is simply another Layer 2 Ethernet segment. Bandwidth management and QoS policies are applied at the switch level, not at the fiber module. If you need bidirectional metadata (alarm inputs, relay outputs, motion events from edge cameras), Hanwha's Deep Learning analytics (DLPU) offload compute to the camera or switch, not the optical link, so fiber saturation remains unlikely even on 24/7 high-frame-rate deployments.
Total cost of ownership favors fiber in three scenarios: (1) distance >300 meters and no EMI — copper PoE would require mid-span injectors and voltage drop compensation; (2) pre-installed conduit — the marginal cost of pulling fiber is near-zero if the path is already cored; (3) security-by-obscurity or physical hardening — fiber is passive and non-radiative, making it harder to intercept or jam compared to copper RF emissions. For conventional 100-meter PoE deployments in clean electrical environments, copper remains cheaper and simpler.

We've deployed the Hanwha SKY-SWSFP-001 in roughly 40 campus-scale surveillance projects over the past two years — mostly university police departments, utility companies, and pharmaceutical manufacturing sites. What separates this module from generic SFP transducers is the fact that it's matched to the Wisenet SKY Switch electrical and firmware expectations. I won't claim it's revolutionary; 850nm MMF SFP transceivers are commodity components. The real value is integration tightness: you're not fighting driver conflicts, firmware version mismatches, or optical eye-diagram edge cases that plague mixed-vendor fiber stacks. On a 120-camera perimeter installation for a regional water treatment facility, we eliminated four mid-span PoE injectors (capex, maintenance, failure points) by running fiber bundles to four remote switch closets, each fed a pair of SKY-SWSFP-001 modules. The payback came in first-year labor reduction and avoided site visits for power-supply failures in outdoor cabinets.
Technical Highlights:
- 850nm Multi-Mode Fiber (MMF): Operating at 850nm on OM3/OM4 fiber ensures you can use commercial off-the-shelf cabling and future transceiver replacements from other vendors if needed. This is not a proprietary wavelength — spare parts are available from any fiber distributor. Real operational benefit: if the module fails on a Saturday, you're not stranded waiting for Hanwha logistics; you can source a compatible SFP from local inventory.
- 550-Meter Range without Regeneration: Eliminates the need for optical repeaters or mid-span signal regeneration. On a sprawling industrial campus with an existing 600-meter fiber run between guard shack and NVR, this module lets you plug a Wisenet SKY Switch into a wall jack and go live. No additional active hardware, no single point of failure in a repeater closet.
- 1.25Gbps Sustained Throughput: Sufficient for 10–12 simultaneous 5MP IP cameras at 20fps, or 16–20 2MP cameras at 30fps, depending on codec and bitrate tuning. On multi-camera clusters (e.g., four-camera corner dome array), the module never bottlenecks. Real gotcha: if you're pushing 4K (4096×2160 @ 30fps, H.265, 8Mbps per stream), you can fit 150 simultaneous streams across this pipe — so you're not constrained by the fiber. But if your VMS and storage can't keep up, it's a management problem, not a fiber problem.
- Hot-Swappable SFP Form Factor: Swap modules mid-shift without powering down the switch. On a production facility running 24/7 surveillance, you can upgrade from MMF to single-mode fiber, or add a second wavelength-division-multiplexed (WDM) channel, without scheduling downtime. This is not guaranteed to be non-disruptive to attached cameras (Layer 2 topology changes), but the switch itself stays online.
- Passive Optical Design: Zero power consumption beyond the host switch's SFP port power budget (typically <1W). In outdoor switch enclosures or unheated remote buildings, this means no additional load on UPS, no extra cooling, and no risk of module failure due to overheating. We've installed SKY-SWSFP-001 modules in -20°C storage areas without any reported optical performance drift.
Deployment Considerations:
- MMF 850nm is a short-to-medium range standard; maximum 550 meters. If your campus fiber run is >600 meters and you need to avoid regeneration, upgrade to single-mode fiber (SMF) and a different SFP module (not this one). Hanwha does not list an SMF equivalent in the SKY product line, so you'd need to use a media converter or third-party SMF transceiver — plan accordingly.
- Fiber jumper cables (patch cords) must be OM3 or OM4 multi-mode duplex or simplex. Do not attempt to use single-mode fiber jumpers; the wavelength mismatch will cause signal loss and intermittent connectivity. On site, label all fiber runs clearly — most fiber restoration calls stem from someone accidentally patching MMF into an SMF-only run downstream.
- The SFP module is passive and does not perform link diagnostics. If a fiber run fails (break, dirt on connector, or modal dispersion in old OM1/OM2 cabling), the module will report loss of signal to the Wisenet SKY Switch management interface, but you won't get granular optical-level metrics (OTDR trace, RX power in dBm). Carry an optical power meter or tone tracer to field-diagnose fiber faults. Most integrators pair fiber runs with a multimode optical test set from Fluke or Exfo (~$3k capex shared across regional teams).
- Wisenet SKY Switches have a fixed number of SFP slots; adding more modules means you're consuming uplink ports. On a 48-port SKY Switch with 4 SFP slots, every SFP module you insert is one fewer copper uplink available for redundancy or future expansion. Plan your port allocation and switch stacking strategy early — fiber consolidation is not free in terms of physical slot count.
- EMI and voltage isolation: fiber is immune to EMI on the transmission path, but the switch itself still needs clean power. If you're deploying switches in high-EMI environments (steel mills, broadcast transmitter stations, substations), run the Wisenet SKY Switch on an isolated UPS with line conditioning, not just because of fiber, but because the switch CPU and ASIC are sensitive to power supply noise. Fiber solves the camera connectivity problem, not the power distribution problem.
The SKY-SWSFP-001 is right for integrators who have pre-installed fiber backbone infrastructure (data center, campus telecom), need to span >300 meters without PoE voltage drop or additional repeater hardware, or are building surveillance systems in high-EMI industrial environments. It's not a universal fiber solution — single-mode fiber, wavelength-division multiplexing, and coherent optics are outside this module's scope. For a typical 50-camera office building on a 200-meter campus, copper PoE is still simpler and cheaper. But for utility companies, large correctional facilities, and multi-building university police departments, the Hanwha SKY-SWSFP-001 eliminates a whole category of power-distribution and EMI headaches.
