- Dominant standard in datacenters and telecoms
- Compatible with SFP/SFP+ modules and LC patch cords
- Available in UPC and APC, single-mode and multimode
SC — universal connectivity
- 24 SC duplex ports = 48 fibers in 1U
- Robust connector, ideal for field and FTTH
- Compatible with older equipment
- Only single-mode OS2 (APC duplex)
2) Fiber type & polarity
OS2 UPC
Long-distance networks, patch connections, return loss >50 dB. Ideal for datacenters.
OS2 APC
FTTH, PON, GPON — return loss >60 dB. Required on carrier networks.
OM3/OM4
Short-distance multimode, 10G/40G/100G up to 100 m. Internal LAN, campus.
Decision matrix — 30 seconds
- Datacenter, server room → LC/UPC OS2 (Ref 22149)
- FTTH / GPON / PON carrier network → LC/APC OS2 (Ref 22165)
- Existing SC connection or field FTTH → SC/APC OS2 (Ref 15858)
- Internal 10G/40G short-distance LAN → LC/UPC OM3/OM4 (Ref 22164)
- Limited budget, all-rack compatible → all models, standard 19" rack
- Multi-bay deployment → LC (48-port density vs 24-port SC duplex)
Optical drawers — all models
All models are 1U 19" rack format, equipped with 48 terminated fibers and delivered ready for installation. Pre-spliced pigtails included.
LC Single-mode OS2 drawers

FAQ — Optical drawer & ODF
Answers to the most frequent questions from fiber installers and network managers.
1How to choose between an LC and SC optical drawer ?
The choice depends on your existing cabling and active equipment:
- LC: compact (1.25 mm), dominant standard in datacenters. 48 ports per 1U. Compatible with SFP/SFP+/SFP28 LC modules. Ideal for maximum density.
- SC: larger (2.5 mm), 24 duplex ports = 48 fibers in 1U. Robust, common on older equipment and field FTTH networks. Compatible with SC simplex or duplex patch cords.
2What is the difference between UPC and APC ?
The difference is in the polishing angle of the ferrule:
- UPC (Ultra Physical Contact): right angle, return loss >50 dB. Suited for data networks (Ethernet, dark fiber, datacenter).
- APC (Angled Physical Contact): 8° angle, return loss >60 dB. Required on PON, GPON, xWDM networks where reflections disturb the optical signal.
3Is this optical drawer compatible with my 19" rack ?
Yes. All 4 ELFCAM models comply with the EIA-310 / DIN 41494 standard for 19" racks. M6 mounting brackets are included. The drawer occupies exactly 1U (44 mm) in height. It is compatible with network cabinets from all brands: Digitus, Lanberg, Navepoint, APC, Schneider, Rittal, Eaton, Legrand, Nexans, etc.
4Are pigtails included and already spliced ?
Yes. Each drawer is delivered fully equipped and fusion pre-spliced at the factory. You don't need a splicer to install the drawer. All you need to do is:
- Mount the drawer in your rack
- Route your multi-fiber optical cable through the cable glands
- Splice the cable fibers to the drawer pigtails (on site)
- Connect your patch cords on the adapter side
5What is the typical insertion loss of the adapters ?
ELFCAM adapters use a zirconia ceramic sleeve (carrier grade):
- Typical insertion loss: ≤ 0.2 dB
- Maximum guaranteed insertion loss: 0.3 dB
- Lifetime: ≥ 500 cycles of mating/unmating
6Does the SC/APC drawer 15858 accept SC/UPC patch cords ?
Not without reservation. The Ref 15858 drawer is equipped with SC/APC adapters (8° angle, green color). Plugging an SC/UPC patch cord (right angle) into an SC/APC adapter is mechanically possible, but return loss will degrade to ~26 dB instead of >60 dB.
For GPON/xPON networks where reflection disturbs the OLT laser, this combination should be avoided. For simple data links without return loss requirements, insertion loss remains acceptable.
Recommendation: always use the same polarity (APC+APC or UPC+UPC) across the entire link.

7Can I use this drawer outdoors or in non-climate-controlled rooms ?
The ELFCAM optical drawer is designed for indoor cabinet installation (rack in server room, technical room, network cabinet). It tolerates temperatures from -20°C to +75°C, which covers unheated technical rooms.
For outdoor installation or humid environments (IP protection required), we recommend using a weatherproof IP55+ cabinet and integrating this drawer inside. The drawer itself is not IP-certified.

8Delivery time and stock availability ?
All 4 models are in stock in France. Delivery is shipped next business day after order (order before 2 p.m.). Delivery via Colissimo or carrier depending on weight. Shipping is free above a certain order amount.
